Comparative Results of Percutaneous Calcaneal Osteotomy in Correction of Hindfoot Deformities

Abstract

Background: Calcaneal osteotomies are often required in the correction of hindfoot deformities. The traditional open techniques, which include a lateral or oblique incision, are occasionally associated with wound healing problems and neurovascular injury. Methods: A total of 122 consecutive patients who underwent a calcaneal osteotomy for hindfoot realignment treatment were included. Fifty-eight patients were operated using an open incision technique and 64 patients (66 feet) using a percutaneous technique. Clinical and radiologic assessments were performed preoperatively, at 6 weeks, and 1 year postoperatively. Results: The American Orthopaedic Foot & Ankle Society scale scores and visual analog scale pain scores improved in both groups postoperatively. The difference between the groups was not significant. The results of the radiologic measurements pre- and postoperatively were not significantly different. No pseudarthrosis occurred in either group. The comparison of both groups showed a significantly lower risk for wound healing problems in the percutaneous group. The hospitalization time was significantly shorter in the percutaneous group. Conclusion: Because of the excellent results with the percutaneous calcaneal osteotomy, the authors feel encouraged to establish this procedure as a standard technique for calcaneus osteotomy, especially patients at high risk for wound healing problems. Level of Evidence: Level III, comparative series.
