摘要:

人体去细胞异体神经拥有广泛的供体来源,可以有效避免对供区神经的损伤,但是急诊一期重建指神经缺损的报道目前还鲜有报道,试验观察了人体去细胞异体神经在伤后6h内重建缺损长度小于5cm的手指神经缺损的可行性和有效性。观察对象为急诊15例18指神经损伤伴缺损,彻底清创后以人体去细胞神经移植重建指神经。重建后随访6-24个月。Mackinnon-Dellon 静态两点辨别觉结果优良率为89%,Semmes-Weinstein尼龙单丝实验轻触觉正常和明显改善率为78%。提示人体去细胞神经移植一期重建手外伤指神经缺损临床操作可行,为缺损周围神经的重建提供了新趋向。

Abstract:

Human acellular nerve allografts have a wide range of donor origin and can effectively avoid nerve injury in the donor area. Very little is known about one-stage reconstruction of digital nerve defects. The present study observed the feasibility and effectiveness of human acellular nerve allograft in the reconstruction of < 5-cm digital nerve defects within 6 hours after injury. A total of 15 cases of nerve injury, combined with nerve defects in 18 digits from the Department of Emergency were enrolled in this study. After debridement, digital nerves were reconstructed using human acellular nerve allografts. The patients were followed up for 6–24 months after reconstruction. Mackinnon-Dellon static two-point discrimination results showed excellent and good rates of 89%. Semmes-Weinstein monofilament test demonstrated that light touch was normal, with an obvious improvement rate of 78%. These findings confirmed that human acellular nerve allograft for one-stage reconstruction of digital nerve defect after hand injury is feasible, which provides a novel trend for peripheral nerve reconstruction.
