The surgical effect of applying reverse sural neuro-fasciomusculocutaneous flap to rehabilitate limb parenchyma wound

Abstract

Objective To evaluate the surgical effect of applying reverse sural neurofasciomusculocutaneous flap to rehabilitate limb parenchyma wound.Methods Assess the size of wound on limb,cut incisor flap from posterior crus,then use sural nerve and nutrient vessel as pedicel.The flag was reversely transfened to rehabilitate limb wound.There are 31 cases with parenchyma wounds,include in lower 1/3 crus wound,ankle wound,heel wound,and foot wound.The size of flap is range from 5cm×6cm to 12cm×17cm.Observe survival rate of surgical flap.Results 26 cases(83.9%)of surgical flag are alive,while 5 cases occurred necrosis on distal superficial flag or part of the flag.The five cases finally healing through secondary suture and skin-grafting.Conclusion As a new surgery therapy,applying reverse sural neuro-fasciomusculocutaneous flap to rehabilitate limb parenchyma wound is effective.It is character with simple,available,do not need to anastomose vessel,reserve main vessel and high survival rate.So it is worth recommend to widely use in clinical practice.
