  1. Note: For patients who underwent conversion to total hip arthroplasty, the survival time is the period between the time of fracture occurrence and the time of total hip arthroplasty. Survival events were defined in patients who did not undergo total hip arthroplasty and had a Harris score higher than 80 points at the last follow-up
