OBJECTIVE: To explore the clinical effect of bone cement-enhanced Asian proximal femoral anti-rotation intramedullary nail (APFN) internal fixation in the treatment of elderly osteoporotic intertrochanteric fractures of the femur and provide it as a more robust treatment to elderly patients with osteoporotic intertrochanteric femoral fractures.

PATIENTS AND METHODS: Between January 2017 and January 2019, 42 patients with osteoporotic intertrochanteric fractures in our hospital were selected. All patients were randomly divided into the proximal femoral anti-rotation intramedullary nail (PFNA) group and APFN group. The PFNA group received conventional PFNA internal fixation, and the APFN group received bone cement-enhanced APFN internal fixation. The operation time, intraoperative blood loss, average fracture healing time, weight bearing time, and hip function recovery of the two groups of patients were evaluated.

RESULTS: All patients were followed up. There was no significant difference in intraoperative blood loss between the two groups. Compared with the PFNA group, the weight-bearing time and hospital stay of the APFN group were significantly shorter. According to the Harris score of hip joint function, the excellent and good rate of the APFN group was better than that of the PFNA group.

CONCLUSIONS: Compared with conventional PFNA internal fixation, cement-enhanced APFN internal fixation has the advantage of early functional reconstruction in the treatment of osteoporotic femoral intertrochanteric fractures. It can significantly shorten the time required for patients to get out of bed and bear weight. It is an effective method for the treatment of osteoporotic femoral intertrochanteric fracture.
