Microsurgical technique combined with free grafting in repairing soft tissue defect of foot and ankle

Objective To observe the application effect of microsurgical technique combined with free grafting in repairing soft tissue defect of foot and ankle.Methods 60 patients with soft tissue defect of foot and ankle treated at our hospital from January,2012 to December,2014 were selected as study objects and were randomly divided into a control group and an observation group,30 cases for each group.The control group were treated with routine pedicled cross-leg flap prosthesis while the observation group microsurgical technique combined with free flap transplantation repair regimen.The repair effects and general indicators of surgery in the 2 groups were compared.Results The hospitalization time was (19.3±4.1) d and the treatment costs was (15 000±3 000) yuan in the observation group,with statistical differences from those of the control group (P＜0.05);The survival rate of flaps and recovery rates of sensory and two-points discrimination were 96.7％,86.7％,90.0％,respectively,the infection rate was 3.3％,and the satisfaction rate of flap shape recovery was 86.7％ in the observation group,with statistical differences from those of the control group (P＜0.05).Conclusions Microsurgical technique combined with free grafting in repairing soft tissue defect of foot and ankle is effective.The recovery of appearance,sensory,and function of flaps is good.The incidence of infection is low.It is worth being generalized.
