Abstract
Purpose: In this study, we evaluated the results of proximal crescentic metatarsal osteotomy performed in patients with for hallux valgus deformity.
Patients and methods: Between July 1999 and November 2002, 14 patients (19 feet) underwent modified McBride procedure and a proximal crescentic metatarsal osteotomy for hallux valgus deformity. All patients were women with a mean age of 41 (range 26-54). A walking cast was applied until the union at the osteotomy site was seen on radiographs, and K-wires used for internal fixation were removed at 6 weeks postoperatively. The mean follow-up was 22 months (5-40 months).
Results: The mean preoperative value of the hallux valgus angle was 38° (34°- 44°), and that of the intermetatarsal angle was 15° (14°-17°). The postoperative values averaged 12° (10°-16°) and 8° (6°-10°) respectively. The mean time for union at the osteotomy site was 6 weeks. At the latest follow up visit, the average AOFAS clinical score was 89 (74-100) and all of the patients but one were satisfied with the appearance.
Conclusion: Crescentic proximal metatarsal osteotomy combined with distal soft tissue reconstruction is an effective technique in correcting hallux valgus deformity with intermetatarsal angle greater than 14°.
