  • RECONSTRUCTION OF AVULSED INJURIES OF HEEL WITH A SENSORY PREFABRICATED FLAP

    ObjectiveTo investigate the effectiveness of using a sensory prefabricated flap to repair the heel avulsion injury. MethodsBetween August 2012 and August 2013, 6 cases of heel avulsion injury were treated. There were 4 males and 2 females, aged 16-54 years (mean, 29 years). The causes were crush injury in 4 cases and wheel twist injury in 2 cases. The injury to admission time was 2-6 hours (mean, 4 hours). The size of skin avulsion ranged from 5 cm×3 cm to 15 cm×8 cm. Avulsion skin had no replanted condition. At one stage operation, the avulsed heel skin soft tissue was made the full thickness skin graft which was fostered on the anterolateral thigh with lateral circumflex femoral artery perforator, and the lateral femoral cutaneous nerve was put beneath the skin to prefabricate the prefabricated flap; at two stage operation, the prefabricated skin flap pedicled with lateral circumflex femoral artery was used to repair the wound, and the lateral femoral nerve was anastomosed with the calcaneal nerve to reconstruct the feeling. ResultsSix prefabricated flaps all survived, and re-plantation flaps survived after operation. The wounds healed by first intention at donor site and recipient site. The patients were followed up 1-2 years (mean, 1.5 years). The flaps had satisfactory appearance and soft texture. At 1 year after operation, the sensation of the flaps was S3, with two-point discrimination of 22-27 mm (mean, 24.3 mm). According to ZHANG Ming's evaluation standards, the results were excellent in 5 cases, and good in 1 case. The patients could walk normally or with weight-bearing; only linear scar formed at the donor site. ConclusionFor patients with heel soft tissue avulsion injury without replantation qualification, a sensory prefabricated flap by the avulsed heel skin soft tissue can transplanted to repair the heel defect. Satisfactory effectiveness can be obtained in heel appearance and function recovery.

MethodsBetween March 2009 and September 2012, 29 cases of dorsal skin and soft tissue defects were treated with improved interosseous dorsal artery reversed island flap. Of 29 cases, there were 17 males and 12 females, aged 23-71 years (mean, 47 years); and the left hand was involved in 12 cases and the right hand in 17 cases. There were 11 cases of avulsion injury, 9 cases of crushing injury, 5 cases of strangulation injury, and 2 cases of traffic accident injury; the interval of injury and admission was 1-7 hours (mean, 4 hours). Two patients had scar contracture. The locations of soft tissue defects were dorsal hands in 21 cases, first webs in 5 cases, and dorsal thumb in 3 cases. The size of soft tissue defects ranged from 4 cm×3 cm to 10 cm×8 cm. One-stage repair was performed in 11 cases, and two-stage repair in 18 cases. The size of flaps ranged from 5.5 cm×4.5 cm to 12.0 cm×10.0 cm. The donor sites were sutured directly or repaired by skin grafting. ResultsAll flaps survived, and wounds healed in first stage. And the grafted skins at donor sites all survived, and incisions all healed in first stage. Twenty-six patients were followed up 3 months-3 years (mean, 19.5 months). Bulky flap was observed in 3 cases, and defatted operation was performed after 6 months; the other flaps had good appearance and texture, and wrist function was normal. According to total angle of motion (TAM) systematic evaluation, the results were excellent in 17 cases, good in 6 cases, and fair in 3 cases at 3 months after operation. ConclusionImproved interosseous dorsal artery reversed island flap has the advantages of easy-to-obtain, simple operation, and high survival rate of flaps, so it is an effective method to repair dorsal skin and soft tissue defect of the hand.

  • APPLICATION OF VENOUS Flow-through FLAP IN FINGER REPLANTATION WITH CIRCULARITY SOFT TISSUE DEFECT

    ObjectiveTo investigate the treatment outcome of applying venous Flow-through flap in the replantation of severed finger with circularity soft tissue defect and vascular defect. MethodsBetween January 2010 and December 2012,11 cases (11 fingers) of severed finger with circularity soft tissue defect and vascular defect underwent replantation with venous Flow-through flaps.There were 8 males and 3 females,aged 18-42 years (mean,24.6 years).The cause of injury was squeeze injury in 6 cases,crush injury in 3 cases,and strangulation in 2 cases.Combined injuries included nerve defect in 3 cases (1.0,2.0,and 3.5 cm in length),and tendon defect in 2 cases (2.0 and 6.5 cm in length); cyclic skin and soft tissue defect was 3.0-4.5 cm in width,was 1/2-1 finger circumference in length,and was 2.0 cm×1.0 cm to 7.0 cm×4.5 cm in size.Six cases had complete circular defect (both finger artery and vein defects),and 5 cases had incomplete circular defect (only finger artery defect),and vascular defect was 1.0-4.5 cm in length.The time from injury to operation was 1.5-4.5 hours. ResultsVenous crisis occurred in 1 case at 2 days after operation,was cured after vein graft; flap edge necrosis was observed in 2 cases and was cured after dressing change and skin grafting respectively; flap edema and blister occurred in 2 cases and relieved spontaneously.The other 6 flaps and replanted fingers survived completely,with primary healing of incision.Ten cases were followed up 12-18 months (mean,15.5 months).Only a linear scar was seen at the donor sites,with no functional limitation.The flaps had similar color and texture to adjacent skin.The two-point discrimination was 6.5-13.0 mm (mean,8.6 mm).According to replanted finger function scoring system of Society of Hand Surgery of Chinese Medical Association,the results were excellent in 6 cases,good in 3 cases,and poor in 1 case at last follow-up,and the excellent and good rate was 90%. ConclusionVenous Flow-through flap can repair both vascular defect and soft tissue defect,so it has good outcome in increasing the survival rate of replanted finger for severed finger replantation with circularity soft tissue defect and vascular defect.
