Résumé
Objective@#To report our clinical application of free fibular composite tissue flap with peroneus longus and brevis in the treatment of complicated extremity trauma.@*Methods@#From August 2014 to September 2017, 5 patients with complicated extremity trauma were treated using a free fibular composite tissue flap with peroneus longus and brevis at Department of Orthopaedics, The Sixth People's Hospital of Shanghai. They were 4 men and one woman, aged from 23 to 52 years (average, 35.1 years). All of them had tendon defects; one had a radius defect, one an ulnar defect and three a tibial defect. The length of bone defects ranged from 8 cm to 18 cm; the size of soft tissue defects ranged from 10 cm × 5 cm to 18 cm ×8 cm. A fibular composite tissue flap was designed according to the soft tissue condition and defect area to repair and fixate the bone defect after thorough debridement and cover the wound before functional reconstruction. Postoperatively, survival of the flap and functional recovery of the corresponding tendon at the recipient site, healing time of the tibia, and wound healing, ankle motion and complications at the donor site were all observed.@*Results@#The 5 patients were followed up for 18 to 38 months (average, 25.2 months). All flaps survived without any vascular crisis or infection. The union time for the fibular graft ranged from 4 to 16 months (average, 8.4 months). In the 3 patients with a tibial defect, the maximum angle of dorsal extension ranged from 0° to 10° and no foot drop was observed. Thumb and digital flexion was reconstructed in the patients with a forearm bone defect only to achieve opposition of index finger and thumb but we failed to make them have a fist. At the 5 flap donor sites, the wound was sutured by the second stage after vacuum suction and healed well; obvious scar formed in one of them. No obvious foot varus was observed at the donor site. The patients were satisfactory with their ankle joint motion. No refracture of the fibular graft occurred during follow-up.@*Conclusion@#A free fibular composite tissue flap with peroneus longus and brevis is a good choice for complicated extremity trauma.

Methods@#To explore the transplantation of flow-through anterolateral thigh flap combined with fibular flap for reconstruction of composite tissue defect at leg.@*Method@#12 cases with leg composite tissue defects were reconstructed by flow-through anterolateral thigh flaps combined with fibular flaps. The skin defects ranged from 6 cm×12 cm to 12 cm×20 cm. The bone defects were 4-10 cm in length.The size of flow-through anterolateral thigh flaps was 14 cm×8 cm to 23 cm×13 cm and the fibular osteocutaneous flaps were 6 cm×4 cm to 12 cm×6 cm. The fibular bone was harvested as 7 cm to 13 cm in length.@*Results@#All the flaps survived in 12 cases. Bony reunion was achieved in all the cases. Vascular crisis happened in 2 cases 1 day after operation. Margin necrosis occurred in distal end of one flap, which healed after dressing. All the flaps had soft texture with satisfactory cosmetic and functional result . There was no complication in donor sites.@*Conclusions@#Flow-through anterolateral thigh flap combined with fibular flap can reconstruct soft tissue defect and bone defect simultaneously. It is the ideal method for leg composite tissue defects.

Objective To investigate the clinical efficacy of using the tissue engineering bone loaded with adipose derived stem cells (ADSCs)and perforator flap in the treatment of composite tissue defects.Methods From April,2013 to June,2015,there were 9 cases of traumatic bone and skin composite tissue defects,including 7 males and 2 females,with an averaged age of 43 years old.The ADSCs were isolated,induced and co-cultured with demineralized bone scaffold.The tissue engineering bone and deep inferior epigastric artery perforator (DIEP) flap were adopted for reconstruction of composite tissue defects.Results All 9 patients were followed up for 12-36 months,averaged of 18 months.The bone growth was obviously for 5 cases with bone defects at the middle and lower part of the tibia.They tolerated full weight bearing walking.One case of middle humeral bone defect demonstrated normal bone tissue growth,and the 2/3 of cross section had been restored.One case of humeral bone defect and 1 case of radial bone defect reached bone union.The remaining 1 with skull defect showed new bone growth,but it had not yet achieved complete bone healing.Conclusion The combination of tissue engineering bone and perforator flap is a minimally invasive,easy accessible and effective method for reconstruction of composite tissue defects.

Objective To determine the outcome of the combined use of flaps transfer and ilizarov technique reconstruct the large soft tissue defects and bone lose in the lower leg.Methods Sixteen patients were identified from a retrospective review from July,2008 to July,2013,who suffered the large soft tissue defects and bone lose in the lower leg and underwent single-stage soft tissue and osseous reconstruction using the flap technique and Ilizarov method.There were 12 males and 4 females aged from 22 to 62 years old (average 42.6 years old).The size of soft tissue defect ranged from 8 cm×9 cm to 30 cm×20 cm.The length of the bone discrepancy ranged from 2 to 14 cm.According to the local condition of the lower leg and the size of the composite tissue defects,10 patients received the free flap covering,6 patients repaired by the saphenous neurocutaneous perforator flap (3 cases) and sural nerve neurocutaneous flap (3 cases).Daily monitoring the skin temperature postoperative.Distraction was commenced on postoperative day 10 to 14 at the rate of 1 mm/day and continued in 4 equal increments.Results The follow-up time ranged from 18 to 36 months.Sixteen flaps survived completed,only 1 flap was observed the venous congestion in postoperative day 2.The duration of ilizarov application ranged from 3.5 to 18.0 months.All patients achieved final union.All patients were satisfied with the outcome of the surgery.Conclusion The combined use of neurocutaneous flap and Ilizarov technique for reconstruction of large composite soft tissue defect in the lower leg.Significantly reduce patient treatment time,improving traction osteogenesis of long bones and the ability of resistance to infection.
