Evaluation of treatment results of the intertrochanter femural fracture with gamma union nail at Tay Nguyen Regional General Hospital

Abstract

Intertrochanteric femoral fractures are commonly seen in the elderly due to osteoporosis, in which the trochanteric region becomes a weakened area, most frequently from falls. In younger patients with preserved bone quality, these fractures typically result from high-energy mechanisms. A variety of treatment methods are currently available, each with its own advantages and limitations. The choice of treatment depends on the facility’s resources, the surgeon’s preference, and the patient’s general condition. This prospective descriptive case series included 35 patients with intertrochanteric femoral fractures treated with internal fixation using the GAMMA UNION intramedullary nail. Closed reduction was performed on a traction table under fluoroscopic guidance at Tay Nguyen Regional General Hospital from May 2021 to October 2022. Results: Patients ranged from 19 to 97 years of age, with a predominance of females (74.3%). The most common mechanism of injury was low-energy falls (77.1%). A majority had associated medical comorbidities (74.3%). According to the AO/OTA classification, type 31A2 fractures accounted for the largest proportion (57%). Anatomical restoration was satisfactory, with bone union achieved in 97.1% of patients; 77.1% regained normal limb length postoperatively. The average hospital stay was 3 days. Most patients achieved hip flexion >90° (94.3%). Functional outcomes were good to excellent in 65.7% of cases according to the Harris Hip Score. Most patients had no early or late complications. No mortality was recorded.
