ABSTRACT
A patient who suffered soft tissue defects of all 5 digits of left hand was referred to the Department of Hand and Foot Surgery, Affiliated Nanhua Hospital, University of South China in January 2020. A quadruple paddled posterior interosseous artery flaps was used to cover the defect in index, middle, ring and little fingers and a free hallux nail flap was used to repair the defect in thumb. Two years after operation, the appearance and texture of the flaps of all digits in the left hand were good. The function of the digits was good as well. There were slightly noticeable scars left in both the donor sites of left forearm and right foot.
ABSTRACT
Objective To explore the method of sensory reconstruction after the operation of reversed island pedicled sural flap and evaluate its therapeutic effect of clinical application. Methods Thirteen clinical cases with traumatic soft tissue defects in heel had recepted the treatment of reversed island pedicled sural flap. All flaps were innervated by anastomosing the distal end of the sural nerve in the flaps and the recipient nerve (superficial peroneal nerve) in end to end or end to side. All patients were evaluated at 9-15 months on the postoperative follow-up parameters, including flap contour, flap stability, locomotor activity,touch sensation, pain sensation, static two-point discrimination, thermal sensibility, and the skin sensory recovery level in lateral dorsutn of foot. Results Thirteen cases flaps had good blood supply and primary healing. All cases were followed up 9-15 months, the rate of good sensory recovery was 53.85%. All pa tients had protective sensory in lateral dorsum of foot, the rate of good sensory recovery was 61.54%. Conclusion Anastomosing the proximal end of sural nerve and superficial peroneal nerve together will be good for the sensory recovery in flap and lateral foot in repairing soft tissue defects in heel with reversed island pedicled sural flap.
