Stabilization of the Chevron procedure for hallux valgus deformity with a capsuloperiostal flap.

This article reports on the use of a Chevron procedure in the treatment of hallux valgus for better stabilization of the osteotomy. This procedure was performed on 31 feet of 24 patients, Twenty-two of the patients were female and two were male. The average age was 41 and average follow-up time was 14 months. The average correction of the 1-2 intermetatarsal angle was 3.8 degrees and average correction of the hallux valgus angle was 15.3 degrees. On the follow-up, 93.5% of the feet were pain free and 81% did not have any discomfort with shoewear. There were two cases of superficial infection, and two patients complained of dysesthesia or hypoesthesia after the operation. Results revealed less correction loss, shorter union time, less metatarsophalangeal stiffness, and more postoperative patient tolerance. The authors attached the distally based "V"-shaped medial capsuloperiostal flap to the metatarsal shaft and, because of obtained stability, used no internal fixation or postoperative cast but only night splint, allowed weightbearing on the heel as soon as the patient tolerated it, and encountered no displacement of fragments, malunion, or recurrence of the deformity.
