Complications on Percutaneous Hallux Valgus Surgery: A Systematic Review.

Lately there has been a growing interest in the use of percutaneous surgery for the correction of hallux valgus (HV). The purpose of the present study was to systematically review the published data about this topic and establish the efficacy and safety, stressing the complication rates found on this percutaneous technique. A systematic review of the literature available in PubMed was performed. The radiological and clinical outcomes were evaluated as well as complication rates. A total of 16 studies were included and 1157 procedures reported for percutaneous HV on 1246 patients. The mean angle correction of HV deformity improved postoperatively. Reported complications vary among the studies. The highest complication rate was joint stiffness in 18.47% of cases, followed by HV recurrence and shortening of M1, both in 15.2%, material intolerance in 10.1%, osteoarthritic changes in 9.1%, infection in 7.6%, and transfer metatarsalgia in 5.4%. There is a lack of randomized control trials and insufficient comparative case control studies to assess whether one technique is more effective than another or if the percutaneous surgery is recommended rather than open surgery with respect to complications.
