To investigate the clinical effect of distally pedicled peroneus brevis muscle flaps and retrograde neurocutaneous flaps on treatment of bone and soft-tissue 3-dimensional defects of the lower leg and foot, the authors retrospectively studied all the patients admitted in their center in 3 consecutive years with bone and soft-tissue defects from March 2008 to February 2011; 21 patients suffering from traumatic and osteomyelitis were treated with peroneus brevis muscle flaps, for obliterating the hole-shaped bony defects after osteomyelitis debridement, and neurocutaneous flaps, for repairing associated soft-tissue defects. After thorough debridement, the average size of soft-tissue defects was 2 cm × 2 cm to 13 cm × 9 cm and that of bony defects was 2 cm × 2 cm × 2 cm to 6 cm × 3 cm × 3 cm. Neurocutaneous flaps completely survived in 20 cases, and the wounds healed at stage I; 1 case developed necrosis in the distal part of the peroneus brevis muscle flap and sural nerve flap, and the wound healed with a saphenous nerve flap. The flaps maintained good texture and shape during a follow-up of 6 to 24 months. Recurrence of osteomyelitis was not observed in any of the patients. In conclusion, distally pedicled peroneus brevis muscle flaps and retrograde neurocutaneous flaps are simple, safe, reliable, and suitable for clinical treatment of hole-shaped bony defects and reconstruction of soft-tissue defects within a single stage, especially when the 2 defects are located in different 3-dimensional spaces.
