What is a phalangeal osteotomy?
An oblique proximal phalangeal osteotomy is introduced as an alternative to the Akin procedure for the treatment of hallux valgus. It consists of a single oblique osteotomy directed from proximal-dorsal to plantar-distal.
What is Wilson’s osteotomy?
Wilson’s osteotomy, first described by Wilson in 1963, is an oblique osteotomy of the first metatarsal with lateral transpositional displacement of the distal bony fragment, resulting in correction of the deformity and shortening of the first metatarsal (26).
What is osteotomy for hallux valgus?
Scarf osteotomy is for moderate to severe hallux valgus deformities. The metatarsal bone of the first foot ray is visible on the inside of the foot following a skin incision. During the osteotomy it is cut in a Z-pattern (repositioning of the bone). It is then secured in a new direction using small screws.
What is a Hohmann osteotomy?
OSTEOTOMY. The Hohmann osteotomy was originally described as an extra-articular osteotomy, although today it is usually performed in conjunction with other procedures, for example, capsule tendon balance of the first metatarso- phalangeal joint (MPJ) and resection of the medial eminence.
What is a proximal phalanx?
The proximal phalanges (hand) are the bones that are found at the bottom of the finger. They are named proximal because they are the closest phalanges to the metacarpals. There are fourteen phalanges in each hand. Three are located in each long finger, and two are located in the thumb.
Where is your proximal phalanx?
The proximal phalanx of the fingers is the proximal, or first bone, in the fingers when counting from the hand to the tip of the finger. There are three phalanges in each finger. The proximal phalanx is the largest of the three bones in each finger; it has joints with the metacarpal and with the middle phalanx.
What type of bone is the proximal phalanx?
The phalanges of the hand are the group of small bones that comprise the bony core of the digits (fingers) of the hand. Even though the phalanges are small in size, they are classified as long bones because of their structural characteristics; each phalanx consists of a shaft, distal head and a proximal base.
What causes a hallux valgus?
Causes of hallux valgus Women are affected more often due to the weaker connective tissue. Splayfoot or skewed foot encourage hallux valgus. An accident can be the cause for hallux valgus. Arthritic changes to the joints can be the cause for hallux valgus.
