OBJECTIVE: Due to a growing number of lateral fragility fractures, and their high economic and social impact, we evaluated the combined drug therapy effectiveness in lateral fragility femur fractures treated by intramedullary nailing surgery comparing the clinical and radiological results of two groups of patients. PATIENTS AND METHODS: From May 2019 to March 2020, we carried out a prospective observational study comparing the results of patients with femoral lateral fractures treated by the same intramedullary nail (PFNA Synthes®) using Clodronic acid and Vitamin D (study group, 25 patients) compared to patients with the same fractures treated with Vitamin D alone (control group, 25 patients). The evaluations were based on bone biochemical markers (serum calcium level, serum phosphate level, parathyroid hormone, Vitamin D, serum C-terminal telopeptide), Visual Analogic Scale and HHS (Harris Hip Score) score, and femur densitometric views. In order to evaluate the femur neck mineral bone density (BMD), two areas have been identified on the Anterior-Posterior view: the Region of Interest (ROI)1 (under the head screw) and the ROI2 (above the femoral screw). The BMD has been calculated using femur densitometric views at T0 (1st day post-surgery) and at T1 (12 months later). RESULTS: As far as the BMD average of ROI1 is concerned, we found a significant statistical increase at T1 in the study group (0.93±0.07 gr/cm2) vs. control group (0.88±0.08 gr/cm2), p=0.04. Both biochemical and densitometric values were statistically increased in the study group from T0 to T1 (p<0.05), while control group showed an improvement in the biochemical values only. CONCLUSIONS: Thanks to a one year follow-up, we are able to demonstrate that the administration of an adequate drug therapy after surgery can lead to a better control of the bone remodeling and reabsorption process.

Abstract

OBJECTIVE: Due to a growing number of lateral fragility fractures, and their high economic and social impact, we evaluated the combined drug therapy effectiveness in lateral fragility femur fractures treated by intramedullary nailing surgery comparing the clinical and radiological results of two groups of patients. PATIENTS AND METHODS: From May 2019 to March 2020, we carried out a prospective observational study comparing the results of patients with femoral lateral fractures treated by the same intramedullary nail (PFNA Synthes®) using Clodronic acid and Vitamin D (study group, 25 patients) compared to patients with the same fractures treated with Vitamin D alone (control group, 25 patients). The evaluations were based on bone biochemical markers (serum calcium level, serum phosphate level, parathyroid hormone, Vitamin D, serum C-terminal telopeptide), Visual Analogic Scale and HHS (Harris Hip Score) score, and femur densitometric views. In order to evaluate the femur neck mineral bone density (BMD), two areas have been identified on the Anterior-Posterior view: the Region of Interest (ROI)1 (under the head screw) and the ROI2 (above the femoral screw). The BMD has been calculated using femur densitometric views at T0 (1st day post-surgery) and at T1 (12 months later). RESULTS: As far as the BMD average of ROI1 is concerned, we found a significant statistical increase at T1 in the study group (0.93±0.07 gr/cm2) vs. control group (0.88±0.08 gr/cm2), p=0.04. Both biochemical and densitometric values were statistically increased in the study group from T0 to T1 (p<0.05), while control group showed an improvement in the biochemical values only. CONCLUSIONS: Thanks to a one year follow-up, we are able to demonstrate that the administration of an adequate drug therapy after surgery can lead to a better control of the bone remodeling and reabsorption process.
