RÉSUMÉ

Objective To approach the design and clinical application of large anterolateral thigh flap and its effect in wound repair.Methods The flaps were designed according to the anatomical features of perforating branches in the anterolateral thigh flaps.When a flap was chipped,a thick branch or a terminal branch of original vessel was reserved,another suitable perforating branch was selected in the proximal or distal end of the flap,and then the two vessels were anastomosed to enlarge the range of blood supply.If the vessel pedicle of a flap was a musculocutaneous perforating branch,the perforating branch of anastomosis was cut at out-point of muscle.If the vessel pedicle of a flap was a intermusclar branch or a direct skin artery,the perforating branch of anastomosis was cut widely.From May 2006 to May 2012,the technique was applied in 28 patients with large skin defect of limbs.The diameters of perforating branches obtained at out-point of muscles were measured during surgery.The survival of flaps was observed after surgery and complications in donor sites were checked during follow-ups.Results There were 18 flaps whose vessel pedicle were musculocutaneous perforating branches.The branches were cut at outpoint of muscles.The diameters of these vessels were measured during surgery.They ranged from 1.3 mm to 1.8 mm with an average of 1.45 mm.All of the vessels could be anastomosed.All 28 flaps survived.All flaps survived.The areas of the flaps ranged from 22 cm × 15 cm to 42 cm × 14 cm.Artery crisis happened in 2 flaps whose vessel pedicle were musculocutaneous perforating branches.The second look operation found that the areas of artery anastomosis of perforating branches and vessel pedicles were compressed by hematoma and thrombus formed.The 2 flaps survived after the hematoma was cleared away and the vessels were reanastomosed.There were no infections.Both the donor and recipient site healed by first intention with no necrosis of flap margin.All 28 patients were followed up by 4-13 months with an average of 8 months.There were no apparent collapse deformities,muscle necrosis,declines of muscle strength and muscle hernia in the donor sites.The appearance of flaps was flat,the color was close to normal and the quality was fine.Conclusion It is a safe and effective method to repair wound surface by large anaterolateral thigh flap obtained by the modus operandi of perforating branch anastomosis.

RÉSUMÉ

OBJECTIVE: To investigate the effects of arc-track private lock pedicle orthopedic fixation system Ⅱ (ALPF Ⅱ) on treatment of spinal diseases. METHODS: A total of 86 patients with spinal diseases were treated using self-made ALPF in the Wendeng Orthopaedic Hospital and were included in this study. Of these patients, 14 suffered from cervical spinal stenosis complicated by cervical vertebral destabilization, 29 from thoracolumbar fractures and dislocations, 15 from lumbar spinal stenosis complicated by lumbar vertebral destabilization, 2 from lumbar spondylolisthesis, 8 from spinal tuberculosis, 6 from ankylosing spondylitis, 9 from idiopathic scoliosis, and 3 from congenital scoliosis. According to conditions, different therapeutic regimens were selected. Postoperatively, regular follow-up was performed to observe vertebral healing, intervertebral height, spinal column sequence, and neurological function recovery. RESULTS: All patients were followed up for 9-30 months (average 12 months). The improvement rate of neurological function, spinal mobility, back pain, and melosalgia was 94.1%, 65.9%, 92.1%, and 87.4%, respectively. The postoperative anterior and posterior vertebral heights were apparently recovered, and kyphotic angle was well corrected. No screw, rod loosening or breakage was found. CONCLUSION: Self-made ALPF Ⅱ is an internal fixation method for treatment of spinal diseases. It provides good reduction, reliable curative effects, less complications, and no biocompatibilities.
