Distal first metatarsal chevron osteotomy

The distal chevron osteotomy is a popular, reliable, effective procedure for correcting hallux valgus deformity and bunions. The procedure has been refined to produce and maintain satisfactory correction and repair. Significant modifications to the original procedure include alteration of the bone cuts and more thoughtful soft tissue releases to improve correction of sesamoid positioning. The most significant improvement involves a change in the osteotomy plane and angle, combined with internal fixation to maintain the correction. Finally, the sharp edge of the superior medial corner of the metatarsal head, identified as a source of excess pressure in shoewear, can be removed and beveled to a smooth rounded surface.
