title: Management of complex open fracture injuries of the midfoot with external fixation.
abstract: Ten patients (11 feet) with severe, high-velocity, open injuries to the midfoot were treated with uniplanar external fixation. The mean patient age was 38 years. Five wounds measured >10 cm, and 3 had extensive degloving of the foot extending into the lower leg. All had grossly comminuted fractures of the tarsal and metatarsal bones: 9 patients had a fractured cuboid; 6 had a fractured navicular; 7 had a fractured cuneiform; and all had metatarsal fractures. Lisfranc joint dislocations were present in 7 feet, and intertarsal dislocations were seen in 3 cases. Six patients underwent split-thickness skin grafting, and 1 required a myocutaneous flap. The average duration of fixator use was 9 weeks (range, 6-15 weeks). Clinically, patients were evaluated 1 year after fixator removal for any residual pain in the foot, ability to stand on tiptoe, presence of a limp, deformity of an arch, and range of motion at the ankle, subtalar, and metatarsophalangeal joints. Each parameter was graded as good, fair, or poor. All patients had sensate plantigrade feet, with 2 patients who experienced pain on weight bearing, 5 who had difficulty standing comfortably on tiptoe, and 2 who limped because of pain. Three patients exhibited flatfoot deformity, whereas 4 had cavus deformity. All demonstrated stiffness at the midfoot and restriction of subtalar and forefoot motion, with 5 also having restricted ankle motion. Radiographically, all fractures were healed at the time of follow-up; 4 were malunited, with 1 demonstrating ankylosis across the tarsometatarsal joint. These results suggest that crush injuries to the midfoot often result in persistent morbidity despite early comprehensive management with external fixation.
