Clamp-assisted reduction and InterTan nailing with limited incision for Seinsheimer V subtrochanteric femoral fractures / 中华骨科杂志

ABSTRACT

Objective:To describe the surgical technique and explore clinical and radiological outcomes of Seinsheimer V subtrochanteric femoral fractures treated by clamp-assisted reduction with limited incision and InterTan nailing fixation.Methods:Data of 22 patients with Seinsheimer V subtrochanteric femoral fractures who were treated by clamp-assisted reduction and InterTan nailing fixation with limited incision in our hospital from January 2015 to June 2018 were retrospectively analyzed. There were 14 men and 8 women with an average age of 62.95±12.44 years (range, 36-81 years). Among them, 7 cases with a big butter-fly fragment were fixed by one cable. After the reduction, the fractures were fixed with InterTan nailing. The operative time, intraoperative blood loss and postoperative complication were recorded. The reduction quality was assessed by postoperative radiography according to the criteria proposed by Baumgartner. The function of the hip joint was assessed by the Harris score and VAS score.Results:All patients were followed up for 18±5.33 months (range, 12-30 months). According to the Baumgartner criteria of reduction quality, anatomic reduction was obtained in 20 cases, and satisfactory reduction was gained in 2 cases. All fractures healed in 4.36±1.36 months (range, 3-8 months). At latest follow-up, the mean Harris scores was 89.05±7.75 (range, 71-100 points), including 11 cases of excellent, 8 cases good, and 3 cases fair (satisfactory rate=86.4%). The mean VAS score was 0.64±0.85 (range, 0-3 points). Two patients had limb length discrepancy which was less than 10 mm. There were no significant complications such as infection, deep vein thrombosis, nonunion, nail cut out and implant failure.Conclusion:Clamp-assisted reduction and InterTan nailing with limited incision for Seinsheimer V subtrochanteric femoral fractures is simple and easy to manipulate, which can achieve anatomic reduction and has good clinical effects.
