Clinical Study On Repair Of Soft Tissue Defect Of Foot And Ankle With Free Anterolateral Femoral Flap And Sural Neurovascular Flap

Objective:To provide a theoretical basis for the better repair of the ankle function of patients with the anterior lateral flap and the cutaneous nerve nutrient vascular flap.Method:In this paper,16 cases of soft tissue defects in the ankle tissue defect of the first affiliated hospital in xinjiang were selected in the first affiliated hospital of xinjiang.According to the operation method,7 cases of free anterolateral femoral flap group（group A）and 9 cases of sural nerve nutrient vessel flap group（group B）were divided into two groups.According to Boyden ankle function evaluation,ankle function score（AOFAS）,sensory recovery,etc.,and by reference to the intraoperative operation time,the amount of blood loss,the area of the flap can be cut for comparative analysis.Results:The average age of group A was 40.8 years（4⁵9 years）,and that of group B was 40.8 years（11⁷0 years）.There was a significant difference in operative time between group A and group B（P<0.05）.The mean operative time in group A was6.67h（4.5⁸.5h）,and the mean operative time in group B was 3.43h（2.2⁷h）.There was no significant difference in intraoperative blood loss（P>0.05）.In postoperative ankle function score,the excellent and good rates of both groups were above 90%.The average area of the flap was 164.6cm²（9cm×9cm²6cm×14cm）in group A and 69.8cm²（3cm×3.5cm¹3cm×18cm）in group B.The sensory recovery of the flap in the operative area of group A and group B was between S₁ and S₂,and the sensory recovery was poor.Conclusion:The flap design of group A was flexible,with high selectivity,and the flap area was large,but the operation time was long,which required high microscopic technique for clinicians.The flap design of group B was simple,the operation time was short,the blood vessels of the flap were relatively constant,and the requirements for the microscopic operation of the surgeon were not high.There was no significant difference in the overall evaluation of ankle function and rehabilitation time between groups A and B.The skin flap appearance of group A was more advantageous than that of group B.If the wound surface is large,it is recommended to repair with free anterolateral femoral flap;if the wound surface is small,sural nerve nutrient vascular flap is an ideal operation.
