What is a proximal osteotomy?
A proximal metatarsal osteotomy is a cut made in the first metatarsal bone, near one end of the bone called the base of the first metatarsal bone which is the one that is near the midfoot. After this cut is made, the rest of the bone is manipulated or pushed inwards and rotated to correct the bunion deformity.
What is Akin osteotomy?
The Akin osteotomy is a medially based closing wedge osteotomy of the proximal phalanx described by OF Akin1 in 1925. It is usually performed for the correction of a hallux valgus deformity in conjunction with a first metatarsal osteotomy, hallux interphalangeal deformity, and long proximal phalanx.
What is a hallux proximal phalanx?
The big toe (known as the hallux) and the thumb each have two phalanges, while the other fingers and toes each have three. The phalanx bones of the toe are shorter than those in the hand. This is particularly true of the proximal phalanx.
What is Crescentic osteotomy?
A proximal crescentic osteotomy can be an effective procedure for triplane correction of a moderate-to-severe hallux valgus deformity with expected improvement in pain and function.
What is distal metatarsal osteotomy?
Abstract. Distal osteotomies are the original osteotomies performed in the first metatarsal for bunion surgery. Many of these can be fashioned to improve an abnormal DMAA. Correction of an abnormally wide first-second IM angle is a goal of the newer procedures.
What is a Cotton osteotomy?
Cotton Osteotomy (Medial Cuneiform Opening Wedge Osteotomy) This surgical procedure helps to create an arch in the foot. It is commonly performed to help correct the condition of pes planus (commonly called flat foot or fallen arch).
What is a metatarsal osteotomy?
A metatarsal osteotomy is a surgical procedure performed to treat a foot deformity. This surgery involves cutting the metatarsal bone of the big toe and realigning the bone to correct the deformity.
How do you make an osteotomy scarf?
Open Surgery – SCARF Osteotomy It involves shaving the prominent bone and realigning the bones with an osteotomy (cut) of the metatarsal combined with a repair of the joint capsule and ligaments. This will produce a narrow foot and a straighter hallux (big toe).
When to use an osteotomy of the proximal phalanx?
Osteotomy of the Proximal Phalanx of the Hallux (Akin Procedure) Metatarsophalangeal (MTP) arthritis with valgus (as primary treatment) The procedure also should be used with caution in a patient with incongruent hallux valgus, a round metatarsal head, and an unstable MTP joint because of the risk of progression or recurrence of the deformity.
Can a phalangeal osteotomy correct a distal articular set angle?
For instance, osteot- omy of the proximal phalangeal base, the original pro- cedure presented by Dr. Akin, has been proposed as a correction for an abnormal distal articular set angle (DASA) (Fig. 8-2) while osteotomy in the distal me- taphysis will predictably correct for an abnormal hal- lux abductus interphalangeus (HAI)3-5(Fig. -3).
Can a phalangeal osteotomy derotate a frontal plane deformity?
However, rotation of the hallux is not present, causing the illu- sion of an asymmetric proximal phalanx. Soft tissue realignment at the metatarsophalangeal joint may very likely derotate the frontal plane deformity and elimi- nate the need for phalangeal osteotomy.
When to get a phalangeal osteotomy for hallux valgus?
Although a painful hallux, often with accompanying pressure against the second digit, is usually the chief complaint, certain reoperative criteria will lead thep practitioner to selection of the phalangeal osteotomy.
