  • CLINICAL APPLICATION OF LINK-PATTERN LATERAL POPLITEAL ARTERY PERFORATOR FLAP IN REPAIR OF POPLITEAL FOSSA SCAR

    ObjectiveTo discuss the feasibility and effectiveness of link-pattern lateral popliteal artery perforator flap in repairing popliteal fossa scar contracture in children or teenagers. MethodsBetween January 2009 and January 2013, 12 patients with popliteal fossa scar were admitted. Of them, 7 cases were male and 5 cases were female, aged from 3 to 17 years (median, 12 years). The disease duration was from 6 months to 5 years (median, 3 years). Wound was repaired with link-pattern lateral popliteal artery perforator flap after remission of popliteal fossa scar. The wound ranged from 6 cm×4 cm to 10 cm×7 cm, and the flap size ranged from 7 cm×4 cm to 12 cm×9 cm. The flap was with lateral sural cutaneous nerve in 5 cases, and lateral sural cutaneous nerve was retained at the donor area of 7 cases. The donor site was repaired using split-thickness skin graft. ResultsAll pedicled flaps and skin graft survived smoothly after operation. The wound at donor site healed by first intention. All the cases were followed up 12-36 months, with an average of 18 months. The flaps had good color, texture, and shape; scar obviously became softened, without hyperplasia or ulceration. The patients were free from lameness with knee range of motion of 0-180°. The squatting function was normal. Grafting skin was smooth in the donor area of the calf, without depression or scar hyperplasia. The senses of posterior-inferior calf and lateral of foot decreased or disappeared in 5 cases of flaps with lateral sural cutaneous nerve; at 6 months after operation, two-point discrimination was 12-14 mm (mean, 13 mm). The posterior-inferior calf was numb and discomfort in 7 cases of flaps with retained lateral sural cutaneous nerve; but after 3-6 months, the sense was obviously recovered, with no sense loss; at 6 months after operation, two-point discrimination was 5-7 mm (mean, 6 mm). ConclusionLink-pattern lateral popliteal artery perforator flap has reliable blood supply and the operation was simple. The cutaneous nerve can be retained in donor area. It is an ideal method for repairing wound after remission of popliteal fossa scar in children or teenagers.

    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.

    ObjectiveTo explore the application value of digital subtraction angiography (DSA) in repairing foot and ankle wounds with posterior tibial arterial perforator flaps. MethodsBetween January 2010 and May 2014, 12 cases of foot and ankle wounds were repaired using posterior tibial arterial perforator flaps. There were 7 males and 5 females with an average age of 36 years (range, 22-54 years). The causes were machine injury in 2 cases, falling injury in 3 cases, and traffic accident injury in 7 cases. The disease duration ranged from 7 to 45 days (mean, 16 days). The size of wound ranged from 6 cm×4 cm to 10 cm×5 cm. Preoperative DSA was performed to observe the orientation and distribution of the posterior tibial arterial perforator and the relationship between perforator vessels. Correspondently, the flaps were designed and harvested. The size of flap ranged from 7 cm×5 cm to 11 cm×6 cm. The donor sites were repaired with skin grafts. ResultsPosterior tibial arterial perforator vessels send out ascending branches and descending branches while going down in the superficial layer. All branches were connected to form vertical chain-form anastamosis, and its orientation was consistent with limb vertical axis. According to DSA results, the flaps were designed and harvested easily. All flaps survived after operation. Meanwhile, wounds healed by first intention. All skin grafts at donor site survived. All patients were followed up 6 months. The flaps had good appearance, color, and texture. No ulcer was found. Affected feet had normal walking function. ConclusionThe size, distribution, and chain-form anastamosis condition of the posterior tibial arterial perforator vessels can be accurately observed by DSA, which provides imaging evidence for harvesting posterior tibial arterial perforator flaps and improves the success rate for repairing foot and ankle wounds.

    ObjectiveTo study the effectiveness of surgical treatment of congenital type V thumb syndactyly. MethodsBetween March 2010 and May 2015, 12 cases of congenital type V thumb syndactyly were treated. There were 7 males and 5 females, aged from 1 to 25 years (mean, 8 years). The right thumb was involved in 8 cases, and the left thumb in 4 cases. There were 2 cases of radial type, and 10 cases of ulnar type. The basement of polydactylism was far away from the carpometacarpal joint in 7 cases, and was close to the carpometacarpal joint in 5 cases (slight ulnar deviation in 1 case). X-ray films showed that the main first thumb metacarpal bone and trapezium fitted well, and 2 cases had the first metacarpal bone deformity. Preoperative individualized treatment plan was made, and polydactylism was excised by the "S" or "Z" incision and simultaneous reconstruction of thenar muscle insertions or adductor muscle insertions was performed; if necessary, wedge osteotomy was used for correction. ResultsAll incisions healed by first intention with no complication. All cases were followed up 6 to 24 months (mean, 12 months). The thumb appearance, flexion and extension, the function of opposition, abduction function were improved significantly in 11 cases with no scar contracture deformity, small first web space, and deviation deformity. One case had slightly narrow first web space. According to hand function criterion, the results were excellent in 10 cases, good in 1 case, poor in 1 case; excellent and good rate was 91.7%.
