I am an accidental authority on metal-metal complications. I observed my first hip replacement in 1979, started assisting on the procedure in 1982, and performed my first as primary surgeon in about 1985.

 I started practice in Alaska in 1992. I was the first up here that had interest in revising failed hips. That interest drove a collaboration with Dartmouth Biomedical Engineering Center (DBEC). DBEC analyses hip explants, I have sent them about a hundred over the years (including my own). They are likely as independent of industry as any academic lab that does this work. They are best known for work that was seminal to the improvements in the polyethylene use in the “Gold Standard” metal-on-plastic and ceramic-on-plastic hips. This work will likely be eclipsed by their evolving analysis of the mechanisms of failure of metal-metal hips.

 I have been captured by why hips fail since training. My first publication was about femoral fractures around hip replacements (periprosthetic fractures), this was my training research topic. It won the big prize at a regional US orthopedic meeting in 1992 and saw print about then in CORR.

 Early in my Alaskan hip revision experience I stumbled over four catastrophic failures of thin XLPE acetabular liners of one design (Zimmer, Longevity, Trilogy). The analysis of those liners by DBEC lead to a podium presentation at the Annual AAOS meeting in 2006 and publication later that year in JBJS-American. Ironically, this experience lead to my selection of the ASR XL as my primary THA several months later. This JBJS paper likely influenced the redesign of the implant systems that use XPLE and relatively large femoral heads (32 mm and greater). This technology, either as Metal-on-Plastic or Ceramic-on-Plastic (CoP) is what I exclusively use now in both primary and revision hip replacement.

 I will not dwell here on my own ASR XL experience as it is well described in my JBJS-American (December 2010) publication that you have a link to on your site. I was the index case and the author of this paper that found that and approximate million metal-metal hip implantees are at risk for cobaltism (systemic cobalt poisoning). The collaboration of DBEC was critical to this work.

Once I realized at the end of 2009 that I had been poisoned by my ASR it was clear that many others might be baffling their surgeons and primary medical providers with a litany of unexplained mental, neurologic, cardiovascular, and thyroid maladies that might be falsely attributed to normal aging or just madness.

This realization stimulated a collaboration with the Alaska State Epidemiologist (Dr. Joseph McLaughlin) that resulted in a May 2010 publication in the Alaska State Epidemiology Bulletin, “Arthroprosthetic Cobaltism (APC) in two Alaskan men.” The June 2010 edition of “Alaska Medicine” featured a paper on the description and diagnosis of Arthroprosthetic Cobaltism (APC) that predated my JBJS publication by 6 months.

The Ak Epi BULL attracted the attention of CDC Atlanta that wished to summarize it for their Weekly Morbidity and Mortality Report. This was nixed by the FDA because a turf issue. The WMMR has national circulation, publication there the summer of 2010 might have saved thousands the grief of metal-metal implantation and tens of thousands the delay in the diagnosis of a progressive multi-organ-system illness.

I was surprised by the FDA’s response. I was naive, I believed the primary mission of the FDA was to protect the public. I started a campaign to educated the FDA about the perils of metal-metal.

At a certain point I was curtly dismissed by the physician in charge of the FDA investigation, “Dr. Tower you do not understand, when the FDA thinks their may be a problem with a device we gather representatives of industry to define the problem, you are not affiliated with industry, you have no standing with us.”

This occurred in the fall of 2010 just before my JBJS publication. Fortunately, to its credit, two years later the FDA is showing interest in metal-metal complications.

My ASR was implanted in March of 2006, within a year it was clear that something about the hip was not right. I had my first metal levels drawn.

My blood cobalt and chromium levels were about 200 times mean normal and 40 times the Biologic Exposure Index (BEI).

The BEI is used as a marker for industrial hygiene, levels below the BEI and thought not likely to be harmful. This peaked my curiosity.

I started to call DePuy design surgeons, distributors, and engineers. I was reassured not to be alarmed, they asserted that such levels were not known to be a problem. I also made inquires to my surgeon and other prominent American hip surgeon authorities on arthroprosthetic design and technique, same story, no worries. I was naive, I believed them, they were the authorities on the topic, they ought to know.

Water over the bridge, but seven years later I am still have difficulties in getting the topic addressed at the annual meeting of the American Academy of Orthopedic Surgeons. The officers of the Academy and the officials that control the Academy’s educational efforts have been closely tied to industry. I was allowed an editorial piece in the AAOS’s monthly newsletter a year ago, “Bad Bearings.” It was sadly prescient.

Frustrated in my efforts to educate surgeons, the FDA, and industry about the risks of the metal-metal hip technology I allowed an interview with Consumer Reports hoping to educate patients directly. Since then I have been contacted by patients from all corners of the world that believe that they might be in trouble. Many have a plausible story for Adverse Local Tissue Response (ALTR) or Arthroprosthetic Cobaltism (APC) but many of those concerned are not at risk (they do not have metal-metal hips).

Getting Dr Steve’s help:

In order for me to make sense of the case history of a concerned individual I need to know the following.

  1. What is the brand and type of hip. This information can be acquired from the surgeon or the hospital, it is best to get the actual implant inventory. All hip components come with duplicate stickers that are placed in the hospital record, copies are often given to the surgeon for the clinic chart. If this is not available the critical factor is the materials of the opposing sides of the hip bearing. If the material mating with the head is plastic their is no risk of cobaltism a long as the hip was not a revision operation for a fractured ceramic socket or head.

  2. If your hip is known to be a metal-metal (all “resurfacings” done over the past decade are metal-metal) the next most important information is a serum or whole blood cobalt level. Your GP can organize that if your surgeon is reluctant.

  3. Your problems at the hip and any decline in mental or general health then needs to be known.The case reports of cobaltism to date suggest that serious mental or general health decline are unlikely if your serum cobalt level is less than 10 micrograms/Liter (mcg/L). Parts per Billion (ppb) are equivalent to mcg/L. If your report returns in nano-moles per liter (nm/Liter) a bit of math will be required to convert to mcg/L. Your metal levels is less helpful in excluding an ALTR problem. Some individuals react to minute levels of chrome-cobalt debris based on an immune mechanism. Several to the most severe cases of tissue destruction that I have seen at revision surgery were in patients with serum or whole blood cobalt levels of less than 1 mcg/L.

If you are concerned that you may have a metal-metal hip related problem contact Earl with the following information.

 The brand, model, and bearing type of your hip.

  1. The date of implantation.

  2. Your serum or whole blood cobalt level.

  3. Any problems that you might be having at the hip.

  4. Any decline that you have experienced in your mental or general health since your hip replacement.

  5. JPEG or DICOM copies of the x-rays of your hip. It is helpful to have those that were done after the operation and the most recent.

Earl will pass that information along to me I will help as best I can. It is important to realize that my advice will be general and should supplement but not supplant the recommendations of your treating physicians.

If your surgeon seems indifferent to your concerns you might be better served by involvement of your primary medical provider.

If you do require revision of your metal-metal hip request that your surgeon send the explants to DBEC for analysis. This is the path to understanding the metal-metal hip debacle and it is this understanding that will prevent future arthroprosthetic misadventures.


Denise asks about Stryker ABG 11 modular stem recall 22 August 21012

Have a question for Dr. Steve. What are your thoughts on the stryker ABG 11 modular stem recall and possible metal issues. I have this stem with a ceramic head and stryker dual mobility ADM cup. It seems to me stem is titanium, neck is co-cr and head is ceramic so not really a metal on metal problem. ADM has the ceramic head on poly shell, titanium cup. This stem was recalled with the rejuvanate which I bleiev has a metal ball which seems to be more of a problem. It seems to me the ABG was just bundled with the rejuvanate due to they are both modular. Thoughts on this? Can it be a problems. Your thought via email would be appreciated.

Dr Steve’s Reply – 25 August 2012

Styker (to my knowledge) never offered a metal-metal bearing hip other than marketing Corin’s resurfacing product in the US but their Rejuvatate stem is a problem with chrome-cobalt debris generated apparently at the modular connection between the stem body and the base of the femoral neck. At this junction the mated surfaces are both chrome-cobalt alloy. It is possible that similar debris might be generated at the modular head neck junction were the mated surfaces might be either chrome-cobalt on titanium or chrome-cobalt on ceramic. The potential problems at both junctions is likely increased if a larger head diameter is used, a longer neck is used, or if a “plus” head is used.

The mechanism by which metal debris is generated at these junctions can be both fretting (micro-motion) or galvanic corrosion. These problems are likely common stems of other brand that have stem/neck modularity (a handful of models and brands) or neck/head modularity with a head diameter of > 36 mm ( many ). Patients that have hips that generate this type of wear likely will not have the markedly high blood cobalt or chrome level that might result in outright systemic toxicity (cobaltism) manifest by damage to the mind (affective, memory, and learning problems ), hypothyroidism, or heart and vessel issues ( cardiomyopathy and hypertension ) but might have problem with tissue inflammation and tissue damage around the hip ( Adverse Reaction to Metallic Debris or ARMD).

ARMD reaction can be serious and might result in a difficult salvage situation for the patient that requires revision surgery and the surgeon that performs the revision. The major problem being the loss of ligaments, tendons, muscle, and bone. Many patients with severe loss of tissue will be condemned to a less than ideal result from their revision surgery with the most common problem being hip instability (dislocations). Most but not all patient with ARMD reactions will note pain and will have increased fluid or soft tissue masses about the hip – cystic (fluid) or solid psuedotumors -. These problem might not be apparent on plain X-ray but are usually found by ultrasound or metal suppression MRI, or CT exam.

Not all of the Rejuvanate stems had a modularity between the neck and the stem body, in the smaller sizes the stem body and the neck are one piece.

I am bothered by the Class Two recall designation. The product is silently removed from the market and surgeons that implanted the devices are notified by letter that there is a potential problem with the device that the surgeon should be aware of but it is not recommended that patients be notified and systematically brought in for review. I think many surgeons will be content to let sleeping dogs lie and not contact their patients and that some might have a smoldering problem in which the symptoms are not bad enough to cause them to contact their surgeon.

This type of recall seems to transfer the liability and responsibility from the manufactureur to the surgeon, to the determent of the patient. In my experience with this type of recall the representative of the company that made the implant is usually present at the time of revision surgery and will request that the explants be surrendered to him or her to be sent to the company’s lab for analysis. When this happens the surgeon and patient never see the explants again and if an inquiry is made as to the results of the “analysis” the answer is typically, “we could not find a problem with the device, the surgeon must have installed it wrong.”

I have been revising hips for twenty years and found and published on defects on implant designs (the combination of the Zimmer Trilogy acetabular shell with a thin cross-linked liner made of Longevity plastic). Though published this information never lead to a recall of any sort, this implant combination was quite common and likely hundreds of patients required revision because of failure of the liner (rim cracking). My paper may have contributed to the design of this product.

These flaws in implant design and the delayed nature of their discovery is being experienced now on a much larger scale with the resurfacing and modular bearing surface metal-metal hips. One system has been formally recalled (the Johnson and Johnson –DePuy – ASR), two others have had class 2 recalls, the Zimmer Durom (transient), and the modular Smith and Nephew metal-metal liners in their R-3 line.

It has been recommended by the British Orthopedic Association that surgeons stop implanting the modular metal-metal hips but most are still no the market. I think this is in essence a “silent recall” and is indicative of unbalanced industry influence on orthopedic professional organizations.

The FDA (US) and MHRA (UK) generally only accept input from orthopedic professional organizations, largely the same surgeons that are consultants to industry. For this reason I believe their response the complications of these devices is emblematic that these “regulatory agencies” are more protective of industry that of patients. This is not overt corruption, these agencies do not have the budgets to do independent pre or post market research. Almost all research on orthopedic devices is funded directly or indirectly by industry,

WOW! Glad to see this question/article. Had a rejuvenate put in on 11/29/2011 and was doing great until April 2012 when I started having some pain with walking and hip flexion. Went to see surgeon and he said xray looks fine just take it easy with the exercising. I am only 35. Things never got better only more pains and issues. Stumbled upon the recall while googling hip/thigh pain after 8 mos post op and went to see surgeon first of August only to be told I probably have muscle weakness and no reason for pain because xray looks good it was not from the rejuvenate at all. He agreed to do lab work at my request. Well, lab work came back this week and chromium was 0.5mcg and Cobalt was 3.9 mcg and he assured me that it was all normal even though it was a “little high”. I asked about an MRI and he told me it wouldn’t show anything because of the metal implant same thing with CT. He offered physical therapy for the “muscle weakness” and popping in my hip and do xrays every 6 months instead of every two years now and watch my levels every 6 months or so. He assured me that the rejuvenate was not my problem and my leveld were not “toxic” and no need to worry. I know that I was doing great right after the replacement and had no pain and now I am going backwards as far as recovery and he thinks the recall has made me “hypersensitive” to the pain. I had synovial chondromatosis for three years before being diagnosed and worked every single day, I am not being hypersensitive. Thanks for the great articles!

Hi Christy

here is Dr Steve’s reply to the points you raised:

Christy ought to request a “Metal Suppression MRI” (MSMRI) and get her implant inventory from her surgeon or from the hospital to confirm that her Rejuvenate stem has a modular connection between the neck and stem body.
New and progressive groin pain with flexion of the hip is common in patient with Adverse Reactions to Medal Debris (ARMDs), this is because the tendon that flexes the hip runs directly over the joint such that increased fluid in the joint or inflammation of the tissues this tendon gets involved and that generates the pain.

I have seen patients with(ARMD) in patients with blood cobalt level of < 3 mcg/L. That Christy’s metal levels are elevated at all suggests that her hip is generating debris somewhere and given that she has a metal-plastic or metal-ceramic bearing couple it is likely that the debris is generated the modular junctions, either at the head neck couple, or at the neck body couple.The metal products generated at the couples tends to be more reactive that that generated at metal-metal bearing surfaces.

Christy can also request her X-rays, I can review them in the context of her implant inventory.

If Christy does get a MSMRI she ought to do some research that the machine and the imaging protocol at the imaging center are current, otherwise the study may be a waste of money. Dr. Hollis (radiologist) is the authority on imaging protocols for hip implants, her work will come up with a “Google Scholar” search. Within my community some imaging centers produce excellent images and some do not. I have found the high quality studies to be very helpful. The imaging time is significantly longer to get a proper study (upward of 45 minutes), a good opportunity to take a nap. There is no exposure to radiation with an MRI, just a magnetic field.

My suggestions are consistent with the recommendations that Styker sent to all of the surgeons known to use Stryker’s implants..Her surgeon’s attention should be directed towards the letter that Stryker likely sent him. If Christy’s surgeon remains reluctant to pursue the recommended imaging she might try to find another surgeon with a specific interest in revision hip arthroplasty. Surgeons that put the Rejuvenate stems in my be in a state of denial, it is human nature not to go out of ones way to find trouble. Addressing premature failure of a hip implant is a time consuming and painful process for the surgeon, the patients are (understandably) distressed about the prospects of a possible early revision surgery and the added hassle and expense of the metal level determinations and the MSMRI. The Stryker stems used with the modular necks can be difficult to extract, particularly if they have been in for a while because the bone grows into the implant surfaces very well with this design (a desirable thing unless one needs to be removed). The last one I took out, just removing the stem took several hours, so the entire time to revision the hip took about four hours (twice the time of a typical first time artificial hip operation) and I am very experienced with this type of operation. If Christy needs to have the hip revised she ought to find a surgeon that is experienced at doing hip revisions, her surgeon may or may be her ideal surgeon to do the revision.

  1. Hi, I have a bit of a question for you, I figured you may be more ‘honest’ than my own doctors!
    In 2006 I received a smith and nephew hip resurfacing, metal on metal, to cut a long story short, finally in september 2011 it was acknowledged I had a big problem! My cobalt and chromium were very high and I had pseudo-tumours around the joint including a large one on my femoral artery. It was also discovered that I had a very slow heartbeat, my pulse sits around 38 – 40 throwing the odd ectopic in for good measure! The cardiologist did various tests, including an echo scan and said he thinks it could be as a result of the cobalt. In addition to this, my hearing loss, tinnitus and allergy type symptoms from 2010 were acknowledged as being connected! I had a ceramic on ceramic revision along with all the nasty bits removed in February of this year.
    The revision never really settled, I eventually had an MRI in september and I am booked in to have another operation this month as I have a pseudo-tumour in the joint measuring 5×1.5. My question initially is whether this is likely to be a recurring thing? They’re going to open me up, hopefully remove the nasty bits again by dislocating the joint rather than taking it right out (all being well) and give it a good clean out, then put me back together again! I am concerned about the psedo-tumours returning!
    Also for the last couple of weeks I’ve been under the weather with flu like symptoms. GP has just given me my second lot of antibiotics, has said I’m presenting with an infection. Could this be as a result of the hip? My hip is very painful, more so than normal! For medication I take Pregablin 300mg 8 2 a day, 30/500mg CoCodamol 2×4 a day and 10mg Oramorph 8 4 a day! In addition to this I take 125mg Fexofenadine as a result of my allergy symptoms from previous. To be honest I shouldn’t function on what I take but I do! My concern is whether my op will be cancelled if I’m still like this, and if they do and my symptoms are connected then I’m in a never-ending circle!
    Sorry for the waffle, just wanted to give you as much info as possible. Incidently, I am in the UK. My solicitor has said after this op he’d like me to see Mr Treacy in Birmingham for a thorough check-up!
    Many thanks for your time

      Hi Tracey,

      It would be very helpful to know how high your blood cobalt got. I think the effects of cobalt on the heart might be common depending on how hard the doctor looks for problems. The most common effect on the heart from high blood cobalt is likely how well the heart relaxes between beats, this is best evaluated by an echocardiogram, when it is present this stiffening of the heart is called “diastolic dysfunction.” Most of our cobalt poisoned patients have had this finding, often it is asymptomatic, but an athletic person might note unaccustomed breathlessness with exercise.

      Has either your hearing or tinnitus improved after your BHR come out? Did you come to require hearing aides? Did you have an audiograms. The case report to date of severe cobaltism have generally noted partial improvement over the course of several years.

      Sounds like some of your problems might be due to peripheral neuropathy (numbness or weakness in the extermities). Electrical nerve studies can document this. The major nerves supplying the leg run close to the hip so that they are particulary prone to damage either by pressure or by high concentrations of metal ions.

      As far as repeat surgery I think you ought to consider the advice of your surgeons, a second opinion might put you at ease.

      As far as your other issues I hope one of your medical doctores has taken and interest in writing up your case for the literature.

      Sincerely,
      Dr. Steve

      Me again,

      I forgot to add that in severe cardiac cobaltism outright heart failure, arrythmias, and fliud in the sac around the heart are common. There was just a case report of fatal arthroprosthetic cobaltism in a Canadian patient. His cobalt level was the highest ever reported (< 1000 mcg/L). I have seen the less severe effects on the heart with blood cobalt levels as low as 23 mcg/L.

    Tracey helloo… I too am in the UK and had a resurfacing in 2006 and have just today found this website… thankfully it has given me lots of information that I can understand..it can be a lonely place when the medical profession look at you as though you crazy when trying to explain how you feel.. I had a revision August 2011 in Birmingham and since before during and after have suffered countless horrid symptons that affect my whole quality of life. Recently had tests done after being referred to a rheumatologist just waiting for results. My hip seems to be ok but the rest of my body is in panic !! I just want to send shed loads of wishes to you of a successful outcome and hope you get back on track soon as … Kind regards Stephanie..

    • stephen tower said:

      Hi Stephanie- I can image that you had a very lonely experience in getting doctors to realize that some of your medical issues might have been related to your BHR. We are learing more but it take time to do studies to sort out what problems might be related to metal-metal hips.

      One way that you can further the understanding is to summarize your problems with your metal levels with a post on Earl’s site. The only way I figured out my ASR was poisoning me was be observing one of my patients in whom I had implanted an ASR.

      I do not think that surgeons realize that they are turning a blind eye to their patients. It is very difficult to reconcile that a therapy has a toxic effect. We are quite human in our weakness for marketing and our ability to rationalize.

      The full extent of the metal-metal hip complications will more likely be documented in the general medical literature rather than in the orthopedic literature. Surgeon-industry conflict of interest is rife in American orthopedics. The FDA relies on organized orthopedics for expert opinion, so there is not likely to be much help from that quarter.

      Earl’s site is a vital resource for patients with concerns and is a great source of the literature to date on metal-metal problems. The big challange for the poisoned or potentially poisoned patient is to find a medical provider that will consider cobaltism to be a possibility. Often that will be a general provider, a neurologist, a cardiologist, a physciatrist, a rhematologist, or an endocrinologist because it is those fields that the problems occur.

        Any thoughts on chromium toxicity and levels that fail to continue to decrease after revision?

  3. Hi, I contacted you in early April about the possibility of metal poisoning being the cause of my optic nerve degeneration, and I just came back from my surgeon’s visit – he had blood work done for me prior to this visit – at the time of my August surgery to remove the metal ball and socket, my chromium was 19.and my cobalt was 63.! Today, he told me my chromium is 1.4 and my cobalt is something like 6.7 (can’t quite remember) but a significant difference in levels at any rate. I have Dr.’s appointments in May for my optic nerve degeneration and a 4th nerve palsy, which we do not know if it is being caused by the metal poisoning, but it is becoming nearly impossible to drive with the double vision and blurring. Just thought I’d touch base.
    Thanks. Corinne Miller

  4. Thank you!!! I’m getting my serum cobalt levels drawn tomorrow, as I have pain, limping, and 20 months after bi-MoM DePuy THRs, I still am not 65% better, plus I have added sadness, depression, anxiety and mood disturbances, plus tinnitus and visual disturbances including double vision that I have NEVER had. My BP is high, though it’s been low for a lifetime, I went to Urgent Care last month for tachycardia last month, which the doc said came from hypothyroidism that was out of control. If all this has been brought on by MoM hips I will gladly endure revision with ceramic/plastic TOMORROW to make it all stop, but my question is… will my insurance company agree to pay for a $90,000+ surgery plus therapy as a way to prevent me from going blind/deaf/crazy/into heart failure? It doesn’t seem to be the insurance companies’ ways, you know? Wouldn’t they want to wait until I am blind and suicidal and in a wheelchair again from pain? I will keep in touch. Your work should be on 60 Minutes. I know people. Want me to reach out? P.S. I DON’T have the DePuy ASR, but do have the MoM that J&J announced Thursday it would no longer produce. I had two of them installed with two HUGE acetabular cups on 9/16/11 at the age of 39.

    I have the Depuy Ceramic on Metal that will no longer be produced or sold. I am 3 1/2 years out and have had the same symptoms as above…only add episodes of headaches with fogginess, paleness (according to my children) and flu-like symptoms, during these episodes BP is way up, otherwise BP is normal. MARS MRI showed hemipelvic cysts that I was told were normal variances. I continue to have pain in the groin and outside hip area, even behind my leg where the top of my leg meets the bottom of my rear. I was so frustrated with the specialist that I told him I wished I had never had the THR and I meant it!! He offered to replace the ceramic head and metal liner with a more traditional metal on plastic, but was quick to say he did not know if that would solve my problems. I, of course, declined his offer and became very emotional at the thought of having to live this way. He then said to have my metal ions rechecked in 3 months and ordered a nerve conduction test too. He said if my ions were up even a little, then that would indicate a problem. However, he is implying that it’s my back and weight that’s causing the problem.

  6. Karen Eichenbaum said:

    Did I mention the specialist my OS referred me to was in a medical group that sits on the board of DePuy?? No wonder he didn’t recommend a revision or listen to my complaints. “He who takes the Kings coins whistles the Kings tune”

    I am preparing for revision surgery in Feb….FINALLY!! I’ve been so sick off and on for the last 4 years, can’t wait to feel some relief. I’ve cut back on the pool exercise because I noticed the more I used the hip the worse my symptoms are. My question is, because I have the Pinnacle ceramic on metal hip, how can I make sure I get this explant? I have an attorney in my family that I thought about asking to help me out, however, do you think that’s necessary? Thank you so much for all your help getting to this point. I wouldn’t have done as much research if it wasn’t for you and Earl. You both are a godsend and my family and I will be forever grateful.

    Thank you, thank you, thank you! You have no idea what it means to me to hear someone else discuss the same problems medically as I do. I’m a 46 year old female, very active prior to my hip resurfacing in 6/2007. I had years of pain & discomfort & was told the resurfacing could only help so much so I carried on. Of course so much more was going on inside my body. I have all of the symptoms,; pseudo tumor, clanking & clicking, exhausted, elevated chromium & cobalt levels in the high 40’s for both. I had revision surgery on 1/10/2014 & was wheeled out of the hospital VOMITING, literally! I had been for the last 14 hours prior yo my discharge! I’m sure now looking back it was because the metal ions were being messed with in my body! I have dropped to 92 lbs & I’m 5’8, the orthopedic surgeon will not even discuss metallosis with me going forward. My heart rate is high @ 120 plus & of course so is my blood pressure. I take potassium daily & have been hospitalized for low potassium levels. The orthopedic doctors response was he will retest my blood levels again in 6 months. I’m so perplexed as to what to do next! Because my prosthetic has not been recalled, no attorney will even talk to you after they find out its not been recalled! There are individuals with NO symptoms that have court cases, but here I sit with life threatening concerns! I pray daily this nightmare will not get worse, I’m only a few weeks from my revision surgery. I’m terrified it could get worse with possible additional surgeries & or permanent disabilities! So far I’ve been instructed that my only recourse is to complete a consumer report with the FDA & I will also contact my insurance company to see if they want to pursue some type of report too. My insurance paid a lot of $ to this doctor & pharmaceutical company! Please, if you have anything you could share with about my journey going forward I would be eternally grateful. I have 3 beautiful children that no longer have their mother & a husband so frustrated because we are so helpless in all of this! I’m not a believer in unnecessary litigation but I can’t believe we can’t even be compensated for what we have spent & our medical costs going forward!  Thank you for taking the time to educate others.

  8. Dr Steve-
    This is a long overdue apology- I should have contacted you earlier. We had a discussion on the blog on my story tims horror story about what kind of hip my depuy pinnacle was.
    You said it was a ceramic on plastic, and I being a trained social worker,,,,,lol of course argued it was ceramic on metal. Looking back I am embarrassed by even questioning you. I can only claim a new DSM disorder called TMHD syndrome- too many hip dislocations syndrome….lol – ok I made it up.
    I really don’t know why I debated with you, but again, I apologize.

    My case is with the other 6000 cases in the bellwether trials in Texas.

    sincerely.

    • I spoke to Dr Steve and his comments were:

      The two are quite equivalent as long as a ceramic head is utilized. I would likely make the decision base on his surgeon’s preference. If the patient is Indonesian he is likely to be relatively small bone, if so the Zimmer MLT stem might “fit” better than the Summit.

    What is the probability of cracking if the ceramic femural head if I have ceramic on crosslinked polyetylene? Thanks

  11. Wow- years later and I am still limping around after my recent THR on my left hip, which was my 5th hip surgery after my 10 dislocations following the initial implant – My pinnacle lawyer of 2 years , now that the bellweather trials will actually start in Texas, has bailed out on me without explanation. My surgeon who removed the damaged pinnacle featured on this blog (Tims horror story) today has denied that the pinnacle was damaged, and stated he does not remember any problem with the implant when he removed it. When I reminded him of his post operative report which stated ” Failed Depuy Pinnacle ” he became irritated. When I reminded him that pictures of the part as he handed it to me in my hospital bed are all over, and it doesn’t take Columbo to see the chunks and chinks of titanium missing form all of the failures and scraping in me. I don’t know what is happening, but people seem to be scattering now that the trials are approaching- I do know that my surgeon is on board with Depuy and likely is well compensated for using their parts. I found this out by pulling the entire staffing list for my surgery, and I was surprised to see that while I was in surgery, 3 DePuy reps were in the OR alongside my surgeon. At any rate, I don’t know if my case will be ok with the metal on metal pinnacles, even though it is a ceramic on poly part, or if I need to find a lawyer to take it as a one off case . I suffered 10 dislocations, and although I did not have a metal on metal liner, it was a Pinnacle. It failed. I have been out of work for 4years, diagnosed with major depression, anxiety, insomnia, and high blood pressure, been turned down for disability because I have a degree, and my family has been homeless for 3 years. MY latest surgery was 6 weeks ago. I need help and cannot find a damn thing in the way of financial support for someone in my position.Any ideas? My email is tjpetri16@gmail.com Thanks
