A Chevron osteotomy is a common bunion correction surgery. The orthopaedic surgeon cuts the end of the long bone leading to the big toe (metatarsal) and slides it toward the outside of the foot to correct the misalignment. This procedure may also be performed in conjunction with soft tissue tightening or loosening around the joint. This osteotomy is mostly performed for mild to moderate bunion deformity.
Correcting a Failed Bunion Repair
Most bunions can be treated without an operation, but sometimes surgical procedures are needed to relieve pain and deformity. Unfortunately, in some cases bunion repairs fail and the bunion returns. Bunions can recur because of medical conditions or non-healing of the bone. Sometimes bunions recur when patients do not follow post-operative instructions.
First MTP Cheilectomy
The first MTP, also called the first metatarsophalangeal joint, is the big toe joint. A first MTP cheilectomy removes bone spurs on the top surface of the big toe joint bones. Bones spurs develop with arthritis (hallux rigidus) of the big toe, and spurs act as a mechanical block to motion, which causes pain.
First MTP Joint Fusion
Arthritis of the first metatarsophalangeal or MTP joint (the big joint of the big toe) can cause pain and swelling. This can lead to difficulty with shoewear and mild activity such as walking. Arthritis develops when the cartilage in the joint wears away and the two bones that make up the big toe joint rub against one another.
First MTP Joint Interposition Arthroplasty
A first metatarsophalangeal (MTP) joint interposition arthroplasty treats arthritis of the big toe. This procedure stops pain by preventing the surfaces of the big joint of the big toe from rubbing together.
First MTP Joint Replacement
A first metatarsophalangeal (MTP) joint replacement treats arthritis of the big toe. The joint is removed and replaced with metal, plastic or a combination of both.
First MTP Joint Resection Arthroplasty (Keller Procedure)
A first metatarsophalangeal (MTP) joint resection arthroplasty treats arthritis of the big toe. This procedure stops pain by preventing the surfaces of the big joint of the big toe from rubbing together.
First MTP Medial Capsulorrhaphy
First metatarsophalangeal medial capsulorrhaphy (MTPMC) is a procedure to tighten the soft tissue envelope that surrounds the big toe joint. This procedure is done to help correct a bunion deformity. Bunions can cause the soft tissue around the joint to stretch out over time, which allows the big toe to turn inward toward the second toe.
Flexor Hallicus Longus Tendon Transfer to the Proximal Phalanx of the Big Toe
A flexor hallicus longus (FHL) tendon transfer to the proximal phalanx of the big toe is used to treat clawing of the big toe. Small muscles in the foot help to stabilize the big toe. When those muscles are weakened by disease, an imbalance occurs that leads to clawing. The clawing results in abnormal pressure to the ball of the foot and can result in the formation of an ulcer. In addition, clawing may lead to pressure on top of the toe from shoewear. Clawing is associated with a variety of underlying disorders, including Charcot-Marie-Tooth disease, diabetic neuropathy, head injury, polio and stroke.
Flexor Hallicus Longus to Peroneus Brevis Transfer
The FHL to PB brevis tendon transfer is a surgery to improve the function of the foot. The FHL is passed behind the ankle to the outside of the foot to either assist or replace the damaged PB tendon.
