Does Hip Resurfacing Restore The Normal Range Of Motion Of The Hip Joint?
Poster Presentation Number: P062 Location: Venetian/Sands EXPO Hall D Adult Reconstruction Hip Justin C Hamaker Houston TX Matthew Thompson, MS Houston TX Sarah Muirhead-Allwood FRCS London United Kingdom Philip C Noble, PhD Houston TX Sean D Doherty Houston TX In this study, we evaluate the efficacy of these procedures in restoring the normal range of motion of the hip joint. Hip resurfacing is becoming a popular alternative to THR because it is perceived as being more physiologic and bone-sparing. In this study, we evaluate the efficacy of these procedures in restoring the normal range of motion of the hip joint. 3D computer models of the pelvis and femur were generated from CT scans of six individuals. CAD models of standard resurfacing components were virtually implanted in each hip. Each femoral component was implanted in 5 degrees more valgus than the native neck shaft angle and positioned without notching of the neck. The range-of-motion (ROM) of each patient was measured before
