Abstract
Objective To evaluate the effectiveness of the treatment with long intramedullary nail and osteosynthesis with plate systems to reconstruct the medial buttress for the subtrochanteric fractures. Methods A retrospective analysis including 26 patients with subtrochanteric fractures was conducted from September 2014 to January 2017. The data of patients: 16 males and 10 females aged 22-70 (40.5±3.5) years. All patients were treated with proximal femur long intramedullary nail and osteosynthesis with plate systems to reconstruct the medial buttress for the subtrochanteric fractures. According to the Seinsheimer type of the subtrochanteric fractures. There were 3 cases of type ⅢA, 2 cases of type ⅢB, 16 cases of type Ⅳ, and 5 cases of type Ⅴ. The postoperative X-ray showed that all subtrochanteric fractures of the femur were well restored. The assessment of the Hip function result was obtained according to the modified Harris hip score. It includes pain, function(gait and activities), relative strength and relative range of movement. Results All of the 26 patients were followed up from 12 months to 36 months (20.5±4.6). All patients obtained good fracture union. The time of the fracture union ranged from 2 to 6 months (3.0±0.8). No fracture displacement, fixation failure varus mal-reduction and femoral head necrosis occurred after follow-up for 12 months. The modified Harris hip scores were 115.5±10.7 (range, 90-120), in which 21 were good, 5 were fair. Conclusions The treatment with long intramedullary nail and osteosynthesis with plate systems to reconstruct the medial buttress for the subtrochanteric fractures could obtain biomechanically stability, reliably fixation and highly fracture union.
