对比分析以自体神经和聚乳酸-羟基乙酸管吻接修复后的特性，为临床坐骨神经损伤吻接术提供生物力学参数。实验取死后24 h 内的新鲜尸体坐骨神经腰段标本12条，切取20个试样，形成10 mm 缺损，分别以自体神经和聚乳酸-羟基乙酸管吻接修复后进行蠕变实验。聚乳酸-羟基乙酸管移植坐骨神经组7200 s 应变上升量大于以自体神经移植组。聚乳酸-羟基乙酸具有很好的蠕变性特性，其蠕变特性符合坐骨神经损伤移植修复生物材料的要求。

To compare and analyze the autologous nerve and PLGA tube kiss repair after connected with theoperation characteris-tics,to provide biomechanical parameters for clinical injury of sciatic nerve kiss.We took a fresh corpse within 24 h after the death of sciatic nerve of 12 lumbar specimens,cut off 20 specimens,the formation of 10 mm defect,and then the creep experiment with autolo-gous nerve and PLGA tubeanastomosis after repair were tested respectively.At 7 200 s,the strain increasing of polylactic acid glycolic acid tube following sciatic nerve transplantation group was greater than that in the autograft group.Polylactic acid -glycolic acid has good creep properties,the creep properties are consisted with the injury of sciatic nerve transplantation for the repair of biological mate-rial requirements.
