Abstract:
Objective:To explore the surgical techniques and outcomes of closed reduction for geriatric subtrochanteric femoral fractures with certain radiological characteristics.Methods:A retrospective analysis was conducted in the 38 aged patients with subtrochanteric femoral fracture who had been treated at Department of Geriatric Orthopedics, Guangdong Provincial Hospital of Chinese Medicine from January 2015 to December 2019. There were 24 females and 14 males, aged from 62 to 95 years (average, 80.9 years). According to the Seinsheimer classification, there were one case of type ⅡB, 7 cases of type ⅡC, 18 cases of type ⅢA, 9 cases of type Ⅳ, and 3 cases of type Ⅴ. The time from injury to operation averaged 2.3 days (from 0.5 to 8.0 days). The fractures of this cohort were characterized by: ①The starting point of the medial fracture line was at the proximal end and the lesser trochanter separated. ②The fracture end was shortened and overlapped on the medial side and angled outward, showing a varus deformity. ③The alignment returned to normal after traction, with only partial lateral displacement left. Before fixation with proximal femoral nail antirotation (PFNA), all these patients were treated by closed reduction in a supine traction bed. In those whose reduction was unsatisfactory, a main nail was inserted or after the main nail was inserted reduction by leverage was performed through the screw blade incision. Intraoperatively, the quality of fracture reduction was evaluated according to the modified Baumgaertner assessment. Recorded were the patients’ operation time, intraoperative blood loss, fracture healing time, hip function and complications.Results:All the fractures achieved 100% of good to excellent reduction (38/38). The operation time ranged from 25 to 120 min (average, 55.6 min) and the intraoperative blood loss from 10 to 150 mL (average, 42.9 mL). This cohort of 38 patients was followed for 10 to 20 months (average, 15.3 months). All the fractures united after 3 to 8 months (average, 4.8 months). The Harris hip scores at the last follow-up ranged from 70 to 94 (average, 81.5). The follow-ups revealed no such complications as internal fixation failure, fracture re-displacement, malunion or nonunion.Conclusion:Closed reduction and PFNA fixation in a supine traction bed can lead to satisfactory clinical effects for the subtrochanteric femoral fractures with certain radiological characteristics in the aged patients.
