Hallux valgus correction by the method of Bösch: a new technique with a seven-to-ten-year follow-up.

Subcapital osteotomy of the first metatarsal is used as the treatment of choice for the correction of hallux valgus. The advantages are a short operation time, no soft tissue procedures, secure union, avoidance of metatarsal head (MTH) necrosis and a varus malalignment. An alternative temporary fixation of hallux valgus also having an arthrosis is performed with a specially developed angle plate (Synthes-Stratec, Austria) with the skin incision lengthened to 1-cm. Adequate displacement of the MTH over the sesamoid bones provides a permanent satisfying result even without an operation on the abductor or the adductor. This article reviews 98 feet of 64 patients who were examined in a follow-up study from the initial 114 cases that were operated. The mean follow-up time was 8 years and 9 months.
