Abstract

Intertrochanteric fractures are rising in frequency due to increasing average life expectancy. According to statistics by Eastell and Lambert¹, there are estimated to be over 1.5 million cases of femoral head fractures in the world, and it is predicted that by 2025, there will be 2.6 million cases. Currently, there are many methods of treating intertrochanteric fractures; conservative treatment has poor results, and surgical treatment is accepted. Implant options for intertrochanteric fracture surgery using proximal femoral intramedullary nails are recommended by the AAOS². The study aims to evaluate the treatment results of intertrochanteric fractures using PFNA at Saint Paul General Hospital, with 90 patients meeting the selection criteria. Results: the average age of the study subjects was 78.04 ± 10.98; The female-male ratio is approximately 2.7 to 1. Fractures are mainly due to daily life accidents, accounting for 82.2%. TAD Index group ≤ 25mm accounts for 88.9% with an average value of 19.19 ± 2.48mm, group > 25mm accounts for 11.1% with an average value of 26.14 ± 0.76mm. Cleveland Index zone 5: Center - Center accounts for 61.1%; the average femoral neck-shaft angle after surgery is 129.32⁰, and after six months, the average is 126.75⁰. Postoperative hip function results at six months, according to the modified Merle d'Aubigné - Postel score, were excellent and good at 72.2%, fair at 26.7%.
