A minimally invasive modified reverse sural adipofascial flap for treating posttraumatic distal tibial and calcaneal...

Our aim was to report a modified reverse sural adipofascial flap for treating posttraumatic distal tibial or calcaneal osteomyelitis. We retrospectively reviewed the records of 15 patients with posttraumatic distal tibial or calcaneal osteomyelitis treated with modified reverse sural adipofascial flaps between 2005 and 2010. The flap was raised through 2 short incisions in the posterior aspect of the lower leg. The raw surface of the flap was covered with a full-thickness skin graft. Donor sites were closed primarily. Lower Extremity Functional Scale (LEFS) scores and 2-point discrimination (TPD) were recorded preoperatively and postoperatively. There were 12 males and 3 females, with an average age of 39 years (range = 18-55 years). Twelve lesions were in the distal tibia and 3 in the calcaneus. The flap ranged in size from 11 × 5 cm to 16 × 7 cm. All flaps survived, and skin grafts healed without complications. Recipient sites had an anatomic contour, and all patients were able to ambulate without the assistance of special shoes or orthoses. No infections recurred, and no ulcers of the grafted skin occurred with the regular wearing of shoes. The follow-up duration was 18.7 ± 6.8 months (range = 12-36 months). The mean LEFS score increased from 22.4 ± 8.3 preoperatively to 53.0 ± 11.2 postoperatively (P = .001). TPD markedly recovered at 24 months postoperatively. The modified reverse sural adipofascial flap provides good outcomes in treating distal tibial and calcaneal osteomyelitis with minimal donor site morbidity.
