Third generation versus fourth generation percutaneous hallux valgus correction: A radiographic analysis of outcomes

Abstract

Percutaneous hallux valgus correction is gaining popularity with foot and ankle surgeons. Various studies have found that the percutaneous approach has increased patient satisfaction and outcomes. The technique of the procedure has some variability with the geometry of the distal osteotomy being the most scrutinized. As of this publication, there has been no comparative studies on the geometry of the distal metatarsal osteotomy. This is a retrospective study of 50 patients who underwent percutaneous correction of a hallux valgus deformity with either a percutaneous transverse or modified chevron osteotomy. The two groups were compared radiographically, preoperatively, and postoperatively using both the intermetatarsal and hallux valgus angles. There is no difference in radiographic outcomes when comparing pre and post-operative IM and HAV angles, and it is the surgeon's comfort levels with a particular geometry of the osteotomy that should determine the approach.
