Sural Nerve Retrograde Island Flap To Repair Distal Leg Soft Tissue Defect

Objectives Explore the sural nerve nutrient vessels of the retrograde island flap in repairing skin and soft tissue defect of lower limbs distal clinical therapeutic effect. Analysis of application of sural nerve and damaged cut flap pedicled with sural nerve repair distal lower limb soft tissue defect of the clinical curative effect.Methods 52 patients were treated with this sural nerve nutrient vessels skin flap Between November 2009 and Jun 2014. Use of them have damage taking flap of sural nerve in 21 cases. The involved cases included 46 males and 6 females, aged range from 6 to 60 years old, average of 32.7. The size of soft tissue defect varied from 3.0 cm×5.0 cm to 8.0 cm×15.0 cm. The size of flap area varied from 5.0 cm×7.5 cm to 10.0 cm×17.0 cm. Intact sural nerve flap cut to, As the principle for. Application damage sural nerve flap harvest, design improvement for the blood supply area, district, flap area. Injury to operating time is 9-45 days. 52 cases of flap pedicle division are not ligatured small saphenous vein.Results Postoperative 52 cases all transplanted tisssues survived 44 cases, distal skin or superficial necrosis in 5 cases, distal part necrosis in 3, the dressing or skin graft treatment of wound healing. The appearance and functional resultswere satisfactory with following up for 8 to 24 months. The color and texture of the flaps were good. The appearance and the function were satisfactory. Application of statistical analysis to repair distal skin and soft tissue defect of lower limbs.Taking flap and intact sural god the application taking flap of sural nerve damage the average length and there was no difference in the average disc one long(P>0.05);More intact sural god and application taking flap of sural nerve injury but there was no difference in the average area, average length and average width(P>0.05);Compare the application in good condition and application of sural nerve injury sura god postoperative survival rate of skin flap, flap flap harvest, there was no difference in the quality of a material with a flap, shape(P>0.05).Conclusions Using the sural nerve retrograde island flap to repair distal leg soft tissue defect in the clinical application effect is satisfied, is ideal for distal leg soft tissue defect area, and sural nerve damage or not are available.
