The Effectiveness of Cross-regional Flap in Repairing Large Tissue Defect in Limbs

Abstract：Objective:To explore the effectiveness of cross-regional flap in repair of ultra-long complex tissue defects in limbs.Method:The cases of large area of composite tissue defect in limbs in the past five years were summarized.The wound of 16 cases were covered firstly by the VSD then repaired in the second stage,13 cases were repaired by combined piece of skin flap in installment,5 cases were repaired by cross-regional joint flap.A total of 34 cases. Result:The average length of stay was 69 days when using the way of skin graft or skin flap to repair after VSD covering.What’s more,the scar hyperplasia was serious in the later period and function reconstructive became more difficult.The average days in hospital were 45 days when using two series free flaps or parallel free flap to repair.There was a flap necrosis in 2 cases,and abdominal pedicle skin flap was performed to repair,the reconstructive function and recovery were satisfied.The average hospitalization was 23 days when using cross-regional flap to repair and the functional recovery and appearance were the best in these three kinds of operation.Conclusion:It could get a good clinical effect when using free cross-regional flap transplantation to repair large area of composite tissue defect and reconstruct function of limbs.
