Bunionectomy (Chevron Bunionectomy) is an outpatient procedure performed to correct a bunion, a common deformity of the foot. Researchers believe the following conditions contribute to the formation of bunions:
Bunions typically develop when pressures of bearing and shifting weight are spread unevenly throughout the joints and tendons in your feet. The imbalance in pressure causes instability in your big toe joint, forcing the joint into a ‘knob’ that juts out beyond the natural shape of your foot.
The surgeon will begin by positioning you for optimal visibility. A regional anesthesia may be administered to prevent any pain during surgery. The surgical area will be sterilized prior to an incision.
An incision will be made alongside the toe to expose the bunion. Your bunionectomy surgeon may remove excess bone at this point, although in many cases this alone is not enough to correct the deformity altogether. Most commonly the bones require realignment in the toe.
The surgeon will carefully cut just below the head of the first metatarsal, allowing the head of the bone to be repositioned. Tendons attached to the toe forcing it out of position may also need to be released.
The head of the first metatarsal is shifted to improve the alignment. Next, the head is stabilized using screws, pins or other fixation devices.
Your surgeon will close the incision and bandage the area. After being monitored briefly you will be permitted to leave. You will also be required to wear a walking cast, splint or surgical shoe before resuming normal activity anywhere between 6-8 weeks.
