Total Hip Arthroplasty: Using clinical performance to guide implant selection
This supplement features studies and registry data related to Corail and Pinnacle THA components.

Introduction

As the population ages and total hip replacement devices and materials continue to evolve, more young patients will undergo total hip arthroplasty (THA). There are numerous options available for both femoral and acetabular components, including the Pinnacle Acetabular Cup System and Corail Hip System (DePuy Orthopaedics, Inc.).

From results presented in 2007 involving 1,183 hips, the overall survival of the Pinnacle cup acetabular component was 99.9%.1 Updated results of this study (May 31, 2011) indicate an all cause (any component) survivorship of 96.1% at 8 years in 1,582 THAs with Pinnacle Cups.2 Importantly, there is data on the specific combination of Corail and Pinnacle. The Joint Registry from England and Wales showed that among 40,879 patients with a Corail and Pinnacle combination, the 5-year survival was 97.7%.3

Surgeons have 25 years of experience with the Corail stem. The Norwegian registry indicates greater than 97% survivorship at 15 years.4 In another study, the 10-year outcomes demonstrated low rates of aseptic loosening and a total reoperation rate below 3%.5

This supplement features studies and registry data related to Corail and Pinnacle THA components. I would like to thank the faculty members for their expertise, as well as DePuy Orthopaedics for sponsoring this Orthopedics Today supplement.
