Lengthening of the midfoot in a case of lower-extremity hemimelia.

Hemimelia of the lower limb belongs to the group of congenital deficiency disorders. The clinical spectrum ranges from minimal shortening of the long bones to severe deficiencies of the extremities. Several etiologies, such as X-rays or drugs, have been implicated to be responsible for hemimelia. In the present report the clinical course and the long-term follow-up of a patient with transverse terminal hemimelia of the left foot at the level of the basis of the metatarsals is described. Due to frequent episodes of pain, development of pressure sores, and an increasing psychological burden, operative intervention consisting of a lengthening procedure using an Ilizarov fixator was indicated. Long-term outcome was good; the patient is now able to painlessly wear conventional shoes and displays a normal gait pattern.
