【摘要】：目的:通过生物力学测试研究腰椎间盘纤维环切口不同修复方法的生物力学强度。方法:选取小牛腰椎标本制成50个脊柱功能节段,每个节段均在纤维环上作一10mm横切口。按照不同修复方法随机平均分为5组:粘合剂组(A组,选用DermaBond粘合切口)、简单缝合组(B组,采用常规U型缝合法处理切口)、MPSS组(C组,采用改良荷包缝合法处理切口)、粘合剂+简单缝合组(D组)及粘合剂+MPSS组(E组),然后进行纤维环抗静水压强度测试及疲劳测试,根据各组的泄露压力和极限转数来评价其修复效果。结果:A~E组的泄露压力分别为(0.76±0.11)MPa、(1.66±0.11)MPa、(1.84±0.15)MPa、(1.88±0.13)MPa、(2.16±0.24)MPa。E组泄露压力明显高于其他组,差异有显著性(P0.05)。在疲劳测试中,从A~E组各组最后的极限转数分别为(4.42±0.59)万次、(8.06±0.75)万次、(8.44±1.01)万次、(9.76±0.23)万次、(9.88±0.21)万次。E组与D组比较差异无显著性(P0.05),与其他各组比较差异均有统计学意义(P0.05)。结论:应用粘合剂+改良荷包缝合法处理纤维环切口,具有较高的生物力学强度。
[Abstract]:Objective: to study the biomechanical strength of different repair methods of lumbar disc fiber ring incision by biomechanical test. Methods: 50 spinal functional segments were made from calf lumbar vertebrae, each of which made a 10mm transverse incision on the annulus fibrosus. According to different repair methods, they were randomly divided into 5 groups: adhesive group (group A, DermaBond adhesive incision was selected), simple suture group (group B, conventional U-shaped suture method was used to treat incision), MPSS group), group C, simple suture group (group B), simple suture group (group B). The incision was treated by modified bag seam method, the adhesive simple suture group (group D) and adhesive MPSS group (group E) were used, and then the hydrostatic strength and fatigue test of fiber ring were carried out. The repair effect was evaluated according to the leakage pressure and limit rotation of each group. Results: the leakage pressure of group A 鈮，
