Inclusion Criteria: * 60 years of age or older undergoing surgery due to a minimally displaced femoral neck fracture * The patient has a health condition affecting physical mobility. * Complete fracture of the femoral neck (AO/OTA 31B) confirmed with anteroposterior and lateral hip radiographs, computed tomography, or magnetic resonance imaging. * Minimally displaced fracture that could be, in the judgment of the attending surgeon, managed with either arthroplasty or in situ internal fixation without reduction. * Low energy injury mechanism. * Surgeons with expertise in internal fixation and total hip arthroplasty or hemiarthroplasty are available to perform surgery. Exclusion Criteria: * The patient is not clinically suitable for either compared treatment. * Expected injury survival of less than 12 months. * Terminal illness with expected survival of less than 12 months. * Incarceration. * Unable to obtain informed consent due to language barriers. * Unable to obtain informed consent because the legally authorized representative was unavailable. * Problems, in the judgment of the study personnel, with maintaining follow-up with the patient. * Currently enrolled in a study or intervention domain that does not permit co-enrollment. * Prior enrollment in the specific platform trial intervention domain. * Patient or legally authorized representative did not provide informed consent (declined participation). * Eligible patient or legally authorized representative was not approached within the screening window (missed participant). * Other reasons to exclude the patient, as approved by the data coordinating center. * Associated lower extremity injury that prevents post-operative weight-bearing. * Retained hardware around the hip that precludes either study treatment. * Infection around the hip (soft tissue or bone). * Pathologic fracture with a lytic lesion in the femoral neck that precludes internal fixation. * Injury did not occur within 21 days of screening. * Patient is too ill, in the judgment of the attending surgeon, for internal fixation. * Patient is too ill, in the judgment of the attending surgeon, for arthroplasty.
