Background: Although percutaneous surgery for the treatment of hallux valgus is popular in Europe, there is sparse English written literature documenting its efficacy. This study described the operative techniques using percutaneous basal closing wedge osteotomy of the first metatarsal in correction of moderate to severe hallux valgus (HV) and its short-term clinical outcomes. We postulated that satisfactory correction of hallux valgus (HV) angle, intermetatarsal (IM) angle, and patients' clinical outcomes could be achieved with this technique. 2) degrees postoperatively (P < .05). IM angle improved from 14.9 (range, 6.7-22.4) degrees to 6.6 (range, 0.9-14.8) degrees (P < .05). The average absolute shortening was 3.8 (range, 0.27-12.91) mm and the relative shortening was 0.8 (range, 0.05-1.91) mm. There was no delayed union or malunion at the osteotomy site. The average AOFAS score improved from 39 (range, 12-50) to 81 (range, 70-93) (P < .05). Conclusions: Satisfactory hallux valgus deformity correction and patients' outcomes were achieved with this technique. Our results are similar to results reported in other studies using open techniques. There was no malunion or delayed union of the osteotomy. Level of Evidence: Level IV, case series study.
