Management of chronic calcaneal osteomyelitis with pull-through abductor hallucis muscle flap -a report of three cases

Abstract

Three patients who had chronic osteomyelitis of the calcaneus were treated with radical debridement of all involved soft tissue and bone and obliteration of dead space with a pull-through abductor hallucis brevis muscle flap. Two patients had calcaneal osteomyelitis without soft tissue loss resulting from previous comminuted calcaneal fractures while a third patient had a large soft tissue defect and calcaneal osteomyelitis resulting from a destructive infection. All of the patients had undergone several surgical procedures for treatment of the osteomyelitis with histories ranging 18 months to 30 months. Following treatment with the pull-through muscle flap there has been no recurrence over the longterm (>two years). We believe that radical removal of all contaminated tissue and immediately coverage with a muscle flap provides an effective single stage treatment of chronic calcaneal osteomyelitis.
