Comparing Total Hip Arthroplasty and Hemi-Arthroplasty on Secondary Procedures and Quality of Life in Adults With Displaced Hip Fractures

Inclusion Criteria: * Adult men or women aged 50 years and old (with no upper age limit) * Fracture of the femoral neck, as confirmed with either anteroposterior or lateral hip radiographs, computed tomography, or magnetic resonance imaging (MRI) * Displaced fracture that is not, in the judgment of the attending surgeon, optimally managed by reduction and internal fixation * Operative treatment is planned within 72 hours of the patient being medically cleared for surgery * Patient was ambulatory prior to the fracture, though they may have used an aid such as a cane or a walker * Anticipated medical optimization for arthroplasty of the hip * Provision of informed consent by patient or proxy * Low energy fracture (defined as a fall from standing height), with no other trauma * Assurance from site that surgeons with expertise in both total hip arthroplasty and hemi-arthroplasty are available to perform surgery (Note: Surgeons do not need to be experts in both techniques) Exclusion Criteria: * Not suitable for hemi-arthroplasty (i.e., inflammatory arthritis, rheumatoid arthritis, pathologic fractures (secondary to cancer), or severe osteoarthritis of the hip) * Associated major injuries of the lower extremity (e.g., ipsilateral or contralateral fractures of the foot, ankle, tibia, fibula, knee, or femur; dislocations of the ankle, knee, or hip; or femoral head defects or fracture) * Retained hardware around the affected hip that will interfere with arthroplasty * Infection aro…
