Plantar Partial Pressure Analysis in a Patient with Reverse Extensor Digitorum Brevis Flap for the Treatment of Hallux Injury.

Introduction: An extensor digitorum brevis (EDB) flap can be used to cover a small soft-tissue defect and has been widely used as pedicled flap to cover defects around the ankle and foot. However, its post-operative functional recovery is unknown. Few reports have evaluated gait after foot flap surgeries, although gait assessment is considered to be necessary for functional evaluation after foot reconstruction. We performed a reverse EDB flap to treat a right hallux injury and conducted a plantar partial pressure (PPP) analysis as a postoperative functional evaluation.
