Objective To study the method and effect of free rectusabdominis muscle flaps with intermediate split thickness skin graft in repairing defects on legs and ankles.Methods From May 1998 to December 2002, 11 cases of defects on legs(2 cases) and on ankles( 9 cases) were repaired by use of unilateral free rectus abdominis flap with skin graft. The soft tissue defects were accompanied by osteomyelitis or the exposure of bone or tendon.The disease course was 1 month to 10 years. The defect size ranged 3 cm×4 cm to 8 cm×14 cm. The area ofrectus abdominis muscle flaps was 4 cm×6 cm to 8 cm×15 cm. Results All patients were followed up 6 months to 4 years after operation. All rectusabdominis flaps survived with good appearances and functions.The primary healing was achieved in 8 cases, intermediate split thickness skin graft necrosed in 3 cases and the wound healed after skin re-graft.Conclusion Free rectus abdominis flap is a proper option for repair of the soft tissue defects or irregular woundson legs and ankles. It has the advantages of abundant blood supply, b anti-infection ability, good compliance and satisfied appearance.
A study was carried out to observe the application of microsurgical technique in the repair defects of soft tissue and infected wounds of extremities. Eighty-three patients with soft tissue defects and infected wounds of extremities were treated by either transferring of vascularized cutaneous flap or transplantation of myocutaneous flap with vascular anastomosis. The result showed that eighty-three patients had gained success after a follow-up of 6 months to 4 years. It was concluded that soft tissue defects and infected wounds of extremities should be repaired as early as possible. Selecting the donor flap near the recipient site was of first choice. The method used for repair should be simple and easily applicable rather these very complicated one. The success depended on the correct treatment of local conditions, resonable design of donor flap and close monitoring after operation.
Objective To investigate the effect of transplantation of the cutaneous iliac flap on repairing bone and soft tissue defect of metatarsal. Methods From October 1999 to December 2003, the cutaneous iliac flap was designed for the repair of bone and soft tissue defect of metatarsal in 4 male patients, whose ages ranged from 26 to 47, with skin graft for the coverage of the iliac flap. The duration of injury ranged from 1 to 5 months. The length of the defect ranged from 4 to 7 cm and the defect area ranged from 5 cm×3 cm to 9 cm×5 cm. Results One week after transplantation, complete survival of iliac flap was observed in 3 cases and partial survival in 1 case (but later proved survived). Callus was seen 1 month after transplantation and Kwires were removed 4months after transplantation. Patients were followed up for 5 to 24 months. There were no ulcers. The ability of walking and bearing was satisfying as well asthe function and shape. Conclusion With satisfying restoration of function and shape, transplantation of the cutaneous iliac flap with skin graft is an alternative to treat bone and soft tissue defect of metatarsal with one stage surgery.
ObjectiveTo evaluate the effectiveness of different flaps for repair of severe palm scar contracture deformity. MethodsBetween February 2013 and March 2015, thirteen cases of severe palm scar contracture deformity were included in the retrospective review. There were 10 males and 3 females, aged from 14 to 54 years (mean, 39 years). The causes included burn in 9 cases, hot-crush injury in 2 cases, chemical burn in 1 case, and electric burn in 1 case. The disease duration was 6 months to 6 years (mean, 2.3 years). After excising scar, releasing contracture and interrupting adherent muscle and tendon, the soft tissues and skin defects ranged from 6.0 cm×4.5 cm to 17.0 cm×7.5 cm. The radial artery retrograde island flap was used in 2 cases, the pedicled abdominal flaps in 4 cases, the thoracodorsal artery perforator flap in 2 cases, the anterolateral thigh flap in 1 case, and the scapular free flap in 4 cases. The size of flap ranged from 6.0 cm×4.5 cm to 17.0 cm×7.5 cm. ResultsAll flaps survived well. Venous thrombosis of the pedicled abdominal flaps occurred in 1 case, which was cured after dressing change, and healing by first intention was obtained in the others. The mean follow-up time was 8 months (range, 6-14 months). Eight cases underwent operation for 1-3 times to make the flap thinner. At last follow-up, the flaps had good color, and the results of appearance and function were satisfactory. ConclusionSevere palm scar contracture deformity can be effectively repaired by proper application of different flaps.
Objective To investigate the method, effectiveness, andclinical application of the anterolateral thigh perforator free flaps for reconstruction of the soft tissue defects in the head and the four limbs after tumorresection. Methods From April 2004 to April 2006, 16 patients (13 males, 3 females; aged 26-72 years) with the soft tissue defects in the head (9 patients) and the four limbs (7 patients) underwent reconstructive operations with the anterolateral thigh perforator free flaps after their tumor resection. The defects ranged in area from 8 cm×6 cm to 20 cm×13 cm in the head with the process of diseases from 6 to 24 months, and the defects ranged in area from 10 cm×7 cm to 21 cm× 12 cm in the four limbs with the process of diseases from 2 to 18 months.The technique for the anterolateral thigh perforator flap freegrafting, the degree of the injury in the donor sites, and the appearance of the donor and recipient sites, and the influence on the anatomy and function in the both local sites were analyzed. Results In the 16 patients with the soft tissue defects in the head and the four limbs after tumor resection, 14 had a primary wound healing (Stage Ⅰ), and 2 had a delayed wound healing (Stage Ⅱ) . Fifteen flaps survived completely but two flaps had a partial failure. Theflap appearance was good and smooth without any severe scarring, and there was a minimal effect on the function at the donor and recipient sites. Conclusion Because of the less morbidity at the donor site, the better result at the recipient site, and the use of the anterolateral thigh perforator flap free grafting, this kind of the technique for reconstruction of the head and fourlimb soft tissue defects after tumor resection is well acceptable.
Objective To establish a new operative method to repair defects of palm and proximal fingers with double vascular pedicle flaps. Methods From August 1992 to June 2000, 20 cases of soft tissue defects of palm and fingers were repaired with double vascular pedicle flaps. Twenty patients included 9 males and 11 females, aged 17-35 years. The causes were crush,avulsion, and so on. The interval between injury and operation was 3-11 hours.The wound area ranged from 8 cm×12 cm to 10 cm×20 cm. We devised the two side flaps on pectoral-umbilical place with well-known blood vessel to cover flexion and extension regions of palm and the multi-lobes skin flap to cover defect of fingers simultaneously. Results Out of 20 patients, 19 were followed up 8-12 months with an average of 9.8 months. All the flaps survived completely. The skin colour and the contour of the palm and digits were good. Conclusion The double vascular pedicle flap is one of the best choices torepair soft tissue defect of the palm and proximal fingers; the procedure is simple and the operation is extended easily.
OBJECTIVE: To investigate the clinical effect of free vascularized thoracoumbilical flap with reversal flow in repairing the soft tissue defect in leg with tibia exposure. METHODS: Forty-four casting mould specimens of leg arteries were studied firstly. Then 25 cases with soft tissue defect and tibia exposure in the proximal-middle segment of leg were adopted in this study. Among them, 18 cases had long distance thrombosis of the anterior tibial vessels or posterior tibial vessels due to traumatic lesion. The maximal size of defect was 28 cm x 11 cm and the minimal size of defect was 11 cm x 9 cm. In operation, the thoracoumbilical flap which was based on the inferior epigastric vessels was anastomosed to the distal end of the anterior tibial vessels or posterior tibial vessels. RESULTS: Anterior tibial artery, posterior tibial artery and fibular artery had rich communication branches in foot and ankle. All the flaps survived, the color and cosmetic result of them were good. CONCLUSION: The free vascularized thoracoumbilical flap with reversed flow is practical in repairing the soft tissue defect of leg with tibia exposure. Either the anterior tibial vessels or the posterior tibial vessels is normal, and the distal end of injured blood vessels is available, this technique can be adopted.
Between 1988 and 1991,27 cases of open fractures of shank bones complicated by soft tissue defect were repaired with fasciocutaneous flaps. The wound surfaces in 11 cases were closed in the first stage and in 16 cases the repair was delayed. The wounds of all the 27 cases had good healing, In fasciocutaneous flaps the blood supply was sufficient and this contributed to subsequent healing. The operation was simple, regardless of the postion of the wound and not damaging the blood vessels. An accurate estimation of the degree of contusion of the soft tissues surrounding the wound was prerequisite to select immediate transposition of fasciocutaneous flapsor delayed transposition.
ObjectiveTo investigate the feasibility of the free descending branch of lateral circumflex femoral artery perforator tissue flap (fascia flap plus skin flap) to repair large soft tissue defects of the extremities and its impact on the donor site. MethodsBetween January 2013 and February 2015, 9 cases of large tissue defects of the extremities were repaired with the free descending branch of lateral circumflex femoral artery perforator tissue flap. There were 8 males and 1 female, aged from 13 to 56 years (median, 36 years). The causes included traffic accident injury in 6 cases and crushing injury by heavy object in 3 cases. Soft tissue defect located at the lower limbs in 7 cases and at the upper limbs in 2 cases, including 2 cases of simple tendon exposure, 2 cases of simple bone exposure, and 5 cases of tendon and bone exposure. After debridement, the soft tissue defect area ranged from 13 cm×7 cm to 20 cm×18 cm. The tissue flaps ranged from 14 cm×8 cm to 23 cm×19 cm. The donor site was directly sutured, scalp graft was used to cover the fascia flap. ResultsAfter operation, partial necrosis of the skin grafting on the fascia flap occurred in 2 cases and healed after dressing change. Arterial crisis occurred in 1 case and the flap survived after anastomosis. The other tissue flaps survived and wounds healed by first intention. The skin grafting healed by first intention in 7 cases, by second intention in 2 cases. The patients were followed up 4-24 months (mean, 10 months). The appearance and function of the tissue flaps were satisfactory, only linear scar was observed at the donor site, which had less damage and no effect on walking. ConclusionFree descending branch of lateral circumflex femoral artery perforator tissue flap can repair large soft tissue defect of the extremities. The donor site can be sutured directly, which reduces damage to donor site and is accord with the principle of plastic surgery.
Objective To introduce the experience of the cl inical appl ication of vertical trapezius myocutaneous flap in repairing soft tissue defects after head and neck tumor resection. Methods Between June 2008 and February 2010, 12 cases of soft tissue defect caused by head and neck tumor resection were repaired with vertical trapezius myocutaneous flap.There were 9 males and 3 females with an age range from 32 to 76 years (median, 54 years). Twelve cases including 2 cases of basal cell carcinoma of orbital skin, 2 cases of squamous cell carcinoma of the parotid gland, 2 cases of submandibular gland mal ignant mixed tumor, 2 cases of metastatic lymph nodes of nasopharyngea carcinoma after radiotherapy, 1 case of squamous cell carcinoma of tongue, and 3 cases of squamous cell carcinoma of occipital skin, and all were classified as TNM stages T3 or T4. The area of soft tissue defect ranged from 13 cm × 6 cm to 25 cm × 13 cm. The vertical trapezius myocutaneous flap ranged from 14 cm × 7 cm to 26 cm × 14 cm and was transfered to repair defect tissue in the homolateral wounds after tumor resection and neck dissection homochronously. The donor sites were sutured directly. Results All incisions healed primarily without infection. Eleven flaps survived except 1 flap with edge necrosis, which was cured after dressing change. Subcutaneous hematocele and effusion occurred in 2 cases on the back after tube was removed at 7 days postoperatively, and they were cured by sucted and pressured dressing. Eleven patients were followed up 1-3 years (mean, 2 years). Nine cases had no tumor recurrence and the flaps had statisfactory appearance; the abduction function of shoulder joint were normal. One case of orbit basal cell carcinoma occurred 3 months after operation and 1 case of nasopharyngeal carcinoma died of brain metastasis 12 months after operation. Conclusion It is an easy and simple therapy to repair head and neck soft tissue defect using the vertical trapezius myocutaneous flap, which can meet the needs of repairing tissue defect of head and neck.
