Primary Total Conventional Hip Replacement
Demographics
There have been 171,104 total conventional procedures reported to the Registry, an additional 23,682 procedures compared to the last report.
Osteoarthritis is the principal diagnosis of total conventional hip replacement (88.3%), followed by avascular necrosis (3.7%), fractured neck of femur (3.6%), rheumatoid arthritis (1.3%) and developmental dysplasia (1.3%).
Total conventional hip replacement is more common in females (55.4%). This proportion has remained constant since 2003 (Figure HT1).
There has been a small increase in the proportion of patients aged 55‐64 years (21.9% in 2003 to 24.9% in 2009). There has been no increase in the proportion of patients younger than 55 years during the same period (Figure HT2).
The use of cementless fixation has increased from 51.3% in 2003 to 62.7% in 2009. During the same period, cemented fixation has declined from 13.9% to 6.3% and hybrid from 34.8% to 31.0% (Figure HT3).
The Exeter V40 and Corail remain the most used femoral stems for total conventional hip replacement. In 2009 these were followed by the Secur‐Fit,
Accolade and CPT (Table HT4).
The percentage of procedures using the ten most used stems has increased from 63.2% in 2003 to 69.3% in 2009. The ten most used cemented and cementless stems are separately listed in Tables HT6 and HT7.
The Trident remains the most used acetabular prosthesis. There has been no change in the five most used prostheses in the last 12 months (Table HT5).
The percentage of procedures using the ten most used acetabular prostheses has increased from 74.9% in 2003 to 77.8% in 2009. The ten most used cemented and cementless acetabular prostheses are separately listed in Tables HT8 and HT9.
