Abstract

Purpose

Nail insertion is the treatment of choice for subtrochanteric femoral fracture, but displacement of proximal bone fragment makes it difficult to find an ideal entry point. Therefore, in this study we aimed to determine the usefulness of treatment of subtrochanteric femoral fracture using Steinmann pin assisted reduction, internal fixation, and insertion of intramedullary nails.

Materials and Methods

We evaluated 33 patients who were followed-up more than a year with a displaced subtrochanteric femoral fracture treated with closed reduction and intramedullary nail fixation between January 2008 and March 2013. In addition, we studied postoperative bone union time, postoperative reduction status, change of the femur neck shaft angle, evaluation of hip joint function, return to daily life, and complications.

Results

All fractures with Steinmann pin assisted reduction were united but they included three cases of delayed union. In Fogagnolo classification, all cases were up to acceptable states and the varus change of femur neck shaft angle was 0.94°±3.1°; no significant difference in Harris hip score was observed between preoperative and last follow-up (p>0.05).

Conclusion

There were satisfactory results in bone union and reduction state with Steinmann pin assisted reduction. Therefore, Steinmann pin assisted reduction is a useful surgical technique for subtrochanteric femoral fracture.
