This surgery is used to treat flexible hammertoe deformity. A hammertoe deformity is one in which the toe is bent and looks like a hammer. A flexible deformity is one in which the toe can be manipulated into a straight position. This deformity can cause shoe problems, corns, and pain with walking.

The flexor hallicus longus (FHL) is the primary flexor muscle of the big toe. It originates at the back of the leg, transitions into a long tendon as it enters the foot and attaches on the bottom of the big toe.

The peroneus brevis (PB) muscle starts in the leg and continues along the outside of the ankle. It then takes a sharp turn and ends on the outside of the foot. The peroneus brevis works with the peroneus longus (PL) to turn the ankle and foot outward. 

A flexor hallicus longus (FHL) tendon transfer to the proximal phalanx of the big toe is used to treat clawing of the big toe.

The flexor digitorum longus (FDL) is one of the tendons responsible for bending the toes down to the floor. The goals of a FDL tendon transfer surgery are to relieve pain and to help restore the arch in patients with painful fallen arches. A fallen arch occurs when the foot loses its support and flattens out, generally due to weakening of tendons and ligaments in the foot.

Adult flatfoot is a condition that is characterized by the collapse of the arch of the foot. Surgery will improve alignment of the foot and restore more normal pressure during standing and walking. A combination of procedures often is needed to repair the ligaments and tendons that support the arch. Bone cuts are made to help restore the arch. Proper correction of flatfoot deformity can help reduce pain and improve walking ability.

First MTP medial capsulorrhaphy is a procedure that tightens the soft tissue on the inner side of the big toe joint. This procedure is done along with other procedures to help correct a bunion deformity. It should not be performed alone due to the likelihood of the bunion returning. Bunions involve both an altered position of the bones of the foot as well as a stretching of the soft tissue around the joint, which allows the big toe to turn inward toward the second toe. Both of these should be addressed to allow long-term correction of a bunion.

The first MTP, also called the first metatarsophalangeal joint, is the big toe joint. A first 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. 

The first MTP, also called the first metatarsophalangeal joint, is the big toe joint. A first MTP joint replacement treats arthritis of the big toe. The bone on either side of the joint is partially removed and replaced with metal, plastic or a combination of both. First MTP joint replacement lessens pain, retains motion, and improves the position of the big toe.

The first MTP, also called the first metatarsophalangeal joint, is the big toe joint. A first MTP joint interposition arthroplasty is a surgical procedure to treat arthritis of the big toe. The treatment can stop pain at the base of the big toe by preventing the surfaces of the bones from rubbing together. It also can preserve some motion in the big toe.

The first MTP, also called the first metatarsophalangeal joint, is the big toe joint. A first MTP joint fusion is a surgical procedure to treat arthritis of the big toe. This condition can cause pain and swelling and lead to difficulty walking, running, and wearing shoes. Arthritis develops when the cartilage on each bone wears away and the two bones that make up the big toe joint rub against one another.

In a first MTP joint fusion, the bones are joined (fused) together permanently so they cannot rub against each other and cause pain.
