Osteotomy

Surgery to change the alignment of, or shorten or lengthen, a bone, by cutting it. Osteotomy is used to correct a hallux valgus that has caused a bunion; coxa vara (a hip deformity); or deformity due to congenital hip dislocation (see hip, congenital dislocation of). The procedure is also used to straighten a long bone that has healed crookedly after a fracture, or to shorten the uninjured leg if a fractured leg has shortened during healing (see leg, shortening of).
