[Intermediate results following subcapital metatarsal osteotomy in the therapy of hallux valgus with metatarsus primus varus].

71 feet were investigated after subcapital modified osteotomy of the metatarsus according to Kramer for an average follow-up period of 19 months. Mean improvement of the Hallux valgus angle was 10 degrees whereas the intermetatarsal angle was improved by 4 degrees on average. The high degree of satisfaction of patients (83%) with the outcome of this surgical method suggest its application in cases of medium metatarsus primus varus within hallux valgus deformations when the metatarso-phalangeal joint is not affected. In patients aged 50 years and older as well as in cases of MT I varus exceeding 18-20 degrees this operation should strictly be limited to the cases indicated above.
