[Percutaneous distal metatarsal osteotomy for the correction of hallux valgus].

OBJECTIVE To evaluate the experience acquired in hallux valgus correction with percutaneous distal metatarsal osteotomy. MATERIAL AND METHODS Retrospective study including patients who underwent percutaneous distal metatarsal osteotomy between May 2005 and May 2007. The age, sex, and number of feet operated on were recorded. The clinical evaluation of results 6 months after surgery using the AOFAS scale, the intermetatarsal angle and the hallux valgus angle were also recorded. RESULTS A total of 40 patients were included; 38 females and 2 males; mean age was 49 years (28-73 years). Fifty-eight osteotomies were performed. According to the AOFAS scale, 28 patients (41/58 feet) had no pain. The mean functional capacity score was 41 points, and an excellent alignment was achieved in 74% of cases. The mean intermetatarsal angle was 7.5 degrees. Complications occurred in 2 patients (2 feet). CONCLUSIONS The appropriate treatment for the correction of hallux valgus consists of minimally invasive procedures, except for the cases in which the metatarsophalangeal joint shows signs of arthrosis.
