Abstract
Objective: To discuss the effectiveness of intramedullary nail fixation with selective cable wiring in the treatment of ipsilateral femoral neck fracture and subtrochanteric fracture. Methods: Between June 2012 and December 2015, a total of 19 patients with ipsilateral femoral neck fracture and subtrochanteric fracture underwent closed reduction of femoral neck fracture and intramedullary nail fixation combined with selective cable wiring. There were 5 males and 14 females with a median age of 52 years (range, 35-77 years). The cause of injury included traffic accident injury in 17 cases and falling injury in 2 cases. According to Garden classification for femoral neck fractures, 7 cases were rated as type Ⅱ, 8 as type Ⅲ, and 4 as type Ⅳ. Femoral subtrochanteric fractures were classified by Seinsheimer classification, with 9 cases as type Ⅱ, 5 as type Ⅲ, 3 as type Ⅳ, and 2 as type V. The interval from injury to operation ranged from 2 to 7 days with an average of 3.7 days. Results: The operation time was 58-125 minutes (mean, 82.4 minutes) and the intraoperative blood loss was 225-725 mL (mean, 289.5 mL). All incisions achieved healing by first intention and no early complication such as infection was observed. All patients were followed up 12-18 months (mean, 13.9 months). At 1 month after operation, the tip apex distance was 9-23 mm (mean, 15.2 mm). All patients achieved bone union with the healing time of 18-42 weeks (mean, 27.4 weeks). One case of hip varus and femoral neck re-displacement (femoral neck shaft angle was 122°) occurred at 3 months after operation, which achieved bone union at 42 weeks after operation. Five patients complained of postoperative pain with the visual analogue scale (VAS) score of 1-3 (mean, 1.8), which did not influence normal life. A total of 16 patients recovered preoperative hip function. During follow-up, no fracture nonunion, femoral head necrosis, implant failure, screw cut-out, and loosening of cable wiring was observed. The Harris hip score (HSS) was 72-92 (mean, 82.8) at last follow-up and 15 patients (78.9%) achieved good hip function. Conclusion: Intramedullary nail fixation combined with selective cable wiring was effective in the treatment of ipsilateral femoral neck fracture and subtrochanteric fracture.
