Background: The present study aimed to assess the impact of teriparatide therapy on Bone Mineral Density, serum Bone Turnover Markers and Radiographic Union Score for Hip (RUSH) in a surgically stabilized osteoporotic intertrochanteric femur fractures and provide a foundation for future research in this domain. Methods: We conducted a prospective study of 40 patients diagnosed with osteoporosis and intertrochanteric fractures, divided into two groups: one managed with proximal femur nailing alone, and the other receiving teriparatide therapy in addition to standard treatment after obtaining informed consent. A comparative analysis was performed between the teriparatide-treated group and the control group receiving calcium supplementation alone. We assessed the influence of teriparatide on fracture union time, bone mineral density (BMD), bone turnover markers (BTMs), and other postoperative complications. Radiographic healing was evaluated using the Radiographic Union Score for Hip (RUSH). Results: All patients were followed for a 6-month period, during which complete fracture union was observed. However, the teriparatide group demonstrated a significantly accelerated fracture union, shortening the healing time by approximately 2 weeks compared to the control group. Additionally, the teriparatide group showed greater improvements in BMD and radiographic union scores. Conclusion: Our findings suggest that teriparatide therapy may promote faster fracture union and improve BMD outcomes in osteoporotic patients with surgically treated intertrochanteric fractures. Nonetheless, further high-quality randomized controlled trials are warranted to substantiate these preliminary findings.
