Study Summary
Each year, hip fracture, an injury that can impair independence and quality of life, occurs in about 280,000 Americans and 36,000 Canadians. By the year 2040, the annual healthcare costs associated with hip fractures are expected to reach $9.8 billion in the United States and $650 million in Canada. It is important to have in place optimal practice guidelines for the surgical handling of this injury. One type of hip fracture, called a displaced femoral neck fracture, is often treated with a hip replacement surgery. Patients undergoing a hip replacement may receive either a total hip replacement, in which the head of the femur and the hip joint socket are replaced, or a partial hip replacement, in which only the head of the femur is replaced. This study will compare the two different hip replacement procedures to determine which one results in better outcomes after surgery in adults aged 50 and older.
Primary Outcome
The primary outcome is any unplanned secondary procedure within 2 years of the initial joint replacement surgery.
Interventions
- DEVICE Total hip arthroplasty
