[The results of treatment of hallux valgus with subcapital osteotomy of the first metatarsal bone].

This paper presents results of wedge subcapital osteotomy of the first metatarsal bone with lateral and plantar translation of the distal fragment in 47 feet (44 women age 37-72) operated for hallux valgus deformity. Bone fragments were stabilized with Kirschner wire introduced obliquely from lateral side of the head to the shaft. Protruding out of the skin part of the wire between I and II toe was shaped parallel to the lateral side of hallux preventing from valgisation. The mean AOFAS score improved from the preoperative value of 49 points to 86 points postoperatively. Hallux valgus angle improved from the mean preoperative value of 38 degrees to 17 degrees after operation. The mean postoperative AOFAS score in the group with major deformity (over 40 degrees valgity and 14 degrees intermetatarsal angle) was 76 points. Proposed method of stabilization allows limited activity without fear of correction loss during bone healing. Clinical and radiological results are similar to other authors' results, indicating that subcapital osteotomy gives satisfactory results in correction of medium grade deformity and disappointing results in severe deformities.
