Abstract

PURPOSE: The authors intended to analyze the operative results of moderate hallux valgus with proximal chevron metatarsal osteotomy and distal soft tissue procedure.
MATERIALS AND METHODS
Seventy feet of fifty-seven patients were followed for more than 1 year after the proximal chevron metatarsal osteotomy. The mean age was 47.2 years, and the mean follow up period was 2 years and 3 months. Clinically preoperative and postoperative AOFAS MP-IP scale and satisfaction after the surgery were analyzed. Radiologically hallux valgus angle, hallux valgus interphalangeal angle, the intermetatarsal angle and sesamoid position before and after the operation were analyzed.
RESULTS
Additional Akin osteotomy was performed 48 out of 70 feet. Clinically AOFAS MP-IP scale was increased from 60.4 points preoperatively to 89.8 points postoperatively. Ninety-four percents of the patients were satisfied with the results. Radiologically hallux valgus angle was decreased from 34.8 degrees preoperatively to 12.8 degrees postoperatively. The intermetatarsal angle was decreased from 15.7 degrees preoperatively to 8.0 degrees postoperatively. Hallux valgus interphalangeal angle was increased from 7.4 degrees preoperatively to 9.8 degrees postoperatively. There were 3 recurrences, 1 hallux varus and 3 minor wound infections. There were no nonunion or malunion of the 1st metatarsal.
CONCLUSION
Proximal chevron metatarsal osteotomy with distal soft tissue procedure and additional Akin osteotomy appears to be safe and satisfactory procedure.
