Patients receiving hip arthroplasty may undergo either a total hip arthroplasty or a hemi-arthroplasty. Which surgical method is best for the patient is unknown. Advocates of total hip replacement claim better improvements in patient function and quality of life. On the other hand, advocates of hemi-arthroplasty, which include most orthopaedic surgeons, claim reduced rates of dislocation and deep vein thrombosis, shorter operating times, less blood loss, and a technically less demanding surgical procedure. This study will compare total hip arthroplasty and hemi-arthroplasty on rates of revision surgery 2 years after patients aged 50 and older sustain femoral neck fractures and undergo surgery. The study will also compare the impact of the two different surgical procedures on function, quality of life, and post-surgical complications. Results from this study may impact current orthopaedic practice.
