Effectiveness of Reverse Sural Artery Flap in the Management of Wheel Spoke Injuries of the Heel.

Objective: Soft tissue injuries at the level of lower extremities, plantar, and dorsal foot pose a surgical challenge for reconstructive surgeons. This kind of injury commonly occurs when lower limbs get stuck in between the spokes of the wheel. Reverse sural artery flap has been proven to be an effective option to cover such defects. The aim of this study is to analyze the demographic variables of affected individuals, technical aspects of reverse sural artery flap, quantify the effectiveness of reverse sural artery flap among various treatment options available, and to study the outcome of injury.

Methods: A total of 49 patients who presented during a period of six years from January 2010 to January 2016 were included in the study. The data was collected using patient's charts, by interviewing the patients, and from hospital records. The patients' wounds were prepared, examined, and the injury was graded depending upon the extent of tissue damage. Tendon and bone defects were repaired, and wounds were closed by either split thickness skin graft or reverse sural artery flaps.

Results: Children were the most commonly affected with no conclusive gender trend. The posterolateral part of the heel of the right foot was the most frequently injured part (69%). Surgical interventions together with proper postoperative care and follow-up produced very good results overall.

Conclusion: Wheel spoke injuries of the heel can be managed without significant morbidity if the patient presents early, the wound is assessed properly, suitable surgical technique is utilized, and good postoperative care is provided.
