A Chevron osteotomy is used for the correction of a mild to moderate hallux valgus deformity. The osteotomy reduces the angle between the first and second metatarsal.

The chevron osteotomy is a commonly performed surgical procedure used to correct mild to moderate hallux valgus deformities, more widely known as bunions. The surgery involves making a V-shaped (chevron-like) cut in the distal portion of the first metatarsal bone, usually near the metatarsal head. By shifting the metatarsal head laterally, the surgeon can realign the joint, reduce the angle between the first and second metatarsals, and improve the overall biomechanics of the big toe. The procedure is generally less invasive compared to more proximal osteotomies and is especially effective when the deformity is not severe.
One of the main advantages of the chevron osteotomy is its relative simplicity and reliable correction in properly selected patients. It allows for good restoration of the metatarsophalangeal (MTP) joint alignment, pain relief, and improved cosmetic appearance. Fixation is often achieved with small screws or pins, and the recovery process typically includes protected weight-bearing in a surgical shoe or boot. Complications are relatively rare but can include recurrence of deformity, stiffness, or, less commonly, avascular necrosis of the metatarsal head if the blood supply is disrupted.
In terms of outcomes, most patients experience significant reduction in pain and improved function, making the chevron osteotomy a preferred technique for younger, active individuals with mild-to-moderate bunions. However, it is less suitable for severe deformities or in cases with significant arthritis of the MTP joint. In such scenarios, more proximal osteotomies, Lapidus procedures, or even joint fusion may be considered. Careful patient selection and precise surgical technique are key factors in achieving optimal results with this method.
