OBJECTIVE: To observe the clinical results of proximal femoral nail anti-rotation (PFNA) combined with zoledronic acid injection in the treatment of osteoporotic intertrochanteric fractures in the elderly. METHODS: 60 elderly patients with osteoporotic intertrochanteric fractures were diagnosed using a dual energy X-ray bone density instrument. Patients were randomly divided into treatment or control groups (30 cases in each group). Patients in both groups were treated by closed/open reduction and internal fixation using PFNA. In the treatment group, patients received one zoledronic phosphonic acid injection of 5 mg/100 ml via intravenous drip, in addition to 600 mg of Caltrate D (qd) and 0.25 mg of alpha ossification alcohol (qd). The control group received 600 mg of Caltrate D (qd) and 0.25 mg of alpha ossification alcohol (qd). The oral drugs were administered for 12 months. Bone pain relief was observed, and changes in the bone mineral density (BMD) of the lumbar and health-side hip were recorded. Clinical results were evaluated using the Visual Analogue Scale (VAS), Harris joint function score, and Osteo- porosis Quality of Life Scale (OQOLS). RESULTS: Compared with the control group, bone pain symptoms were significantly alleviated (p < 0.05) in the treatment group. In the treatment and control groups, both between-group and within-group differences in BMD were significantly increased in L1e4, femoral neck and trochanter (p < 0.05). No significant differences were found...
