Hallux valgus correction using a modified Hohmann technique

Abstract

In 181 patients presenting with hallux valgus (247 toes), we performed a modified Hohmann procedure with Kirschner wire fixation of the osteotomy. Follow-up by a questionnaire was possible in 159 patients representing 217 operated toes (21 reoperations), and roentgenograms of bony healing were assessed in all these patients. The questionnaire was returned by 91% (145/159) of the patients. The average observation time was 52 months (25-97 months). The average correction of the hallux valgus angle was 10 degrees, ranging from 31.4 degrees before surgery to 21.4 degrees after surgery. Eighty-eight percent of the patients stated that they had an excellent or good/fair result, and 12% had pain or problems with footwear. We found a positive correlation among the correction of the valgus angle, the lateral displacement, shortening of the first metatarsal, and the overall result. No correlation was found among the plantar displacement, correction of the intermetatarsal angle and the result. The modified Hohmann procedure is, in our opinion, a safe and reliable procedure for treating hallux valgus deformity of the foot.
