clinical evaluation of patients with pertrochanteric fractures treated with gamma nail in 5th azar educational and therapeutic center

Background and objectives: due to the high incidence of intertrochanteric fractures in the elderly, their significant morbidity, and the lack of consensus regarding the optimal treatment method, we decided to evaluate the clinical status of patients treated with gamma nail fixation. methods: in this cross sectional study, out of 67 patients with pertrochanteric fractures treated with a gamma nail between 2018 and 2020, about 43 cases were included. patients were followed monthly until callus formation was observed on radiographs. at the final follow-up, the harris hip score (hhs) was determined, and radiographic and clinical outcomes were assessed according to the ao classification. results: the mean age of the patients was 60.7 ± 21 years, and the mean time to union was 15.1 ± 8.9 weeks. the mean hhs was 76.1 ± 24, of which 12 patients (28.1%) had excellent, 19 patients (44.1%) good, 2 patients (4.6%) fair, and 10 patients (23.2%) poor results. there was no significant difference in hhs among different ao fracture types (a1, a2, a3) (p = 0.16). the mean pain score in the hhs was 35.5 ± 10.69. no significant difference in pain score was found among the a1, a2, and a3 groups (p = 0.25). the mean hhs for fractures near the base of the femoral neck was 67.33, for intertrochanteric fractures 81.81, and for intertrochanteric–subtrochanteric fractures 63.5. conclusion: the use of gamma nail is an effective treatment method for pertrochanteric fractures, resulting in good to excellent clinical and functional outcomes (based on hhs) in more than 70% of cases.
