Abstract：BACKGROUND:Doubld-action hemiarthroplasty and total hip arthroplasty are reliable methods to treat intertrochanteric fracture of femur in the elderly, but which is better remains controversial in the clinic. OBJECTIVE:To observe the practical effect of prosthetic replacement with different methods in treatment of intertrochanteric fracture of femur in the elderly, and to assess the clinical value. METHODS:A total of 54 elderly patients with intertrochanteric fracture of femur at the age of over 65 years old were randomly assigned to two groups. In the observation group (n=27), patients underwent graded cement double-action arthroplasty. In the control group (n=27), patients received cementless total hip arthroplasty. They were folowed up for 2 years. Harris scores were recorded in the two groups so as to assess the therapeutic effects. Folow-up recurrence rate, adverse events and host response to materials were analyzed. RESULTS AND CONCLUSION: The therapeutic effects were similar between the observation and control groups (89%, 81%;P > 0.05), but recurrence rate of 2-year folow-up was significantly lower in the observation group than in the control group (4%, 30%;P < 0.05). Moreover, dislocation, acetabular wear and loosening were not found. Results indicate that the midterm effects were similar between graded cement double-action arthroplasty and total hip arthroplasty in treatment of intertrochanteric fracture in the elderly, but graded cement double-action arthroplasty significantly decreases the recurrence rate.
