  • FREE VASCULARIZED POPLITEAL ARTERY CUTANEOUS BRANCH FLAP FOR REPAIR OF WOUND ON FOOT AND ANKLE

    ObjectiveTo investigate the feasibility and effectiveness of free popliteal artery cutaneous branch flap anastomosed with lateral tarsal artery and vein for the repair of wound on the foot and ankle by anatomical observation and clinical application. MethodsLatex was poured into the blood vessels of 8 cadavers, then perforator vessel of posterolateral upper calf was dissected, and the popliteal artery cutaneous branch flap was designed with a pedicle of 2.5 cm in length; the lateral tarsal artery of the foot was dissected, could be freed to 6 cm in length; the diameter of these vessels was measured, and the number of the accompanying veins was counted. Between March 2010 and January 2013, 13 cases of foot and ankle wounds were repaired with popliteal artery cutaneous branch flap anastomosed with lateral tarsal artery and vein. The size of flaps ranged from 6.0 cm×4.0 cm to 7.5 cm×5.5 cm. There were 11 males and 2 females, aged from 41 to 65 years (mean, 47.3 years). The causes of injury included traffic accident in 8 cases, crushing in 4 cases, and twist by machine in 1 case. The size of wounds, ranged from 5.0 cm×3.5 cm to 7.0 cm×5.0 cm. The donor sites were sutured directly. ResultsAccording to anatomical observation, the popliteal artery cutaneous branch flap was designed by using the lateral popliteal artery perforator for shaft. The vessel of the pedicle perforator flaps from the popliteal artery cutaneous branch flap matched well with the lateral tarsal artery. Clinical results: vascular crisis occurred in 2 flaps, which survived after symptomatic treatment; the other flaps survived, with primary healing of wound and incision at donor site. The patients were all followed up 5-18 months (mean, 11 months). The flap had normal color and good elasticity. Second stage operation was performed to make the flap thinner in 3 female patients because of bulky flaps. The remaining patients had no obvious fat flap. According to American Orthopaedic Foot and Ankle Society (AOFAS) score for evaluation of the ankle function at 6 months after operation, the results were excellent in 7 cases, good in 5 cases, and fair in 1 case, with an excellent and good rate of 92.3%. ConclusionFree popliteal artery cutaneous branch flap anastomosed with lateral tarsal artery and vein for the repair of wound on the foot and ankle is simple and effective. The donor site is hidden.

  • TREATMENT OF LEG, FOOT, AND ANKLE WOUNDS WITH SAPHENOUS NEUROCUTANEOUS VASCULAR FLAPS COMBINED WITH ASSEMBLY EXTERNAL FRISKET FOR FIXATION IN PARALLEL-LEG POSITION

    ObjectiveTo explore the effectiveness of a new method to repair severe soft tissue defects of the leg, foot, and ankle with contralateral saphenous neurocutaneous vascular flaps combined with assembly external frisket for fixation in parallel-leg position. MethodsBetween August 2009 and August 2013, 29 cases with leg, foot, or ankle wound were treated. There were 18 males and 11 females, with an average age of 37.6 years (range, 11-65 years). The interval of injury and operation was 14-36 days (mean, 22.3 days). The locations were the planta pedis and heel in 5 cases, the dorsal foot in 2 cases, the ankle in 4 cases, middle and lower leg in 14 cases, and upper leg in 4 cases. The area of trauma ranged from 5 cm×3 cm to 19 cm×9 cm. The assembly external frisket was used for fixation in parallel-leg position; a bridge flap was transplanted to repair defects, and the area of flap ranged from 6 cm×4 cm to 22 cm×11 cm. The donor sites were directly sutured or repaired with skin graft. The pedicle of the bridge flap was cut off and the assembly external frisket was removed after 3-4 weeks. ResultsThe flaps in all patients survived completely; primary healing of wound and incision at donor site was obtained. The patients were followed up 6-18 months (mean, 13.2 months). The appearance of flaps was satisfactory, and the sensation of the heel recovered. Moreover, the patients had a comfortable feeling, and the ankle and knee joints can move freely, and had good function. ConclusionThe assembly external frisket in parallel-leg position instead of cross-leg can make patients comfortable position, and achieve reliable fixation. The saphenous neurocutaneous vascular flap has the advantages of no need for anastomosis vein and for sacrifice of the main vein. Contralateral saphenous neurocutaneous vascular flap combined with assembly external frisket for fixation in parallel-leg position is a favorite method to repair severe soft tissue defects of the leg, foot, and ankle.

  • Application of perforator propeller flap of lower limb in the treatment of foot and ankle defect in children

    Objective To investigate the effectiveness of perforator propeller flap of lower limb in the treatment of foot and ankle defect in children. Methods The clinical data of 28 children with foot and ankle defect treated with perforator propeller flap of lower limb between January 2018 and January 2021 were retrospectively analyzed. There were 18 boys and 10 girls with an average age of 7.3 years (range, 6-14 years). There were 8 cases of traffic accident injury and 20 cases of chronic infection wound. The disease duration was 2-4 months, with an average of 2.8 months. After thorough debridement, the residual wound size ranged from 5 cm×4 cm to 9 cm×5 cm. Repairing was performed after 7-28 days of the infection in control. According to the location, size, and shape of the wound, the perforating vessels were located by ultrasonic Doppler, and the perforator propeller flap (area ranged from 6 cm×5 cm to 11 cm×6 cm) was designed and harvested to repair the wound. Flap transfer combined with free split-thickness skin graft covered the wound in 2 cases. The donor site was sutured directly (22 cases) or repaired with skin graft (6 cases). Results Twenty-six flaps survived, of which 20 cases were in primary healing, and 6 cases had epidermal necrosis at the end of small paddle, which healed after dressing change. Necrosis occurred in 2 cases due to venous crisis which healed after anterolateral femoral flap free transplantation. Primary wound healing was achieved in donor site. All 28 children were followed up 6-24 months (mean, 10.5 months). The texture, shape, and motor function of the lower limb was satisfactory. At last follow-up, the American Orthopaedic Foot and Ankle Association (AOFAS) score was 89.8±8.0, which was significantly different from the preoperative score (79.6±10.4) (t=−11.205, P<0.001); 20 cases were excellent, 6 cases were good, and 2 cases were poor, and the excellent and good rate was 92.8%. ConclusionThe perforator propeller flap of lower limb in children has its own characteristics. It is a reliable method to repair the foot and ankle defect in children.
