【Abstract】 Objective To study the method to reconstruct the sensation of the sural island skin flap by the way of end-to-side neuro-anastomosis and to observe the effects. Methods Sural flaps from posterior tibial were used to repair soft tissue defects around heel in 8 patients and their esesations were reconstructed by the way of end-to-side neuro-anastomosis with nerves around heel.The effects wre observed at 2,4,8,16,24 weeks. Results After 4～18 months follow-up,the walking and weight bearing functions of the affected limbs were good.The sensation of the flaps recovered in different degree by 4 week after operation and the extent and range gradually increased.The function of the donor nerve was not affected. Conclusion The sensation of the sural island skin flap could be restored by the way of end-to-side anastomosis,and the effects were satisfactory in repairing the soft tissue defects around the heel and the proximal part of foot.更多还原
