자가골이식을 이용한 단중족골증의 수술적 교정

Abstract

Brachymetatarsia, one of the rare congenital foot anomalies, is due to abnormally short metatarsal. It frequently affects the fourth toe and is more common in females. It may be produced by premature closure of the epiphysis of a matatarsal but the exact etiology is unknown. Most patients want correction of brachymetatarsia because of the cosmetic problem rather than the functional one.

Though both conservative treatment and surgical correction can be used, lengthening of the abnormally short metatarsal with autogenous bone graft is the treatment of choice.

We experienced 4 cases of brachymetatarsia, 3 cases are bilaterally affected and 1 case unilateral. We lengthened the skin and soft tissue with V-Y plasty, lengthened the extensor tendon with Z-plasty and, performed horizontal osteotomy of the metatarsal and interposing autogenous iliac bone graft. Postoperative result showed excellent outcome in aethetic as well as functional aspect.

We would like to present the detailed operative techniques and related bibliographical review.
