Acute management of major trauma involving the foot and ankle with Hoffmann external fixation.

Massive trauma involving the foot was treated by external fixation in 33 cases and followed for 1 to 3 years. Amputations were performed in seven (21%) because of uncontrollable deep sepsis in two and massive injury in five. The other 26 (79%) had functionally acceptable feet at follow-up, but all had some stiffness and cosmetic deformity. Complications attributed to the Hoffman external fixation were limited to three pin tract infections. We recommend Hoffmann external fixation when it is necessary to: 1) stabilize major open fracture dislocations; 2) maintain length where bone is lost or extensively comminuted; 3) prevent soft tissue contractures; 4) control joint position for delayed ankle arthrodesis; and 5) provide easy access for soft and bone tissue reconstructions.
