【精品】兔肘关节尺侧副韧带急性损伤手术与非手术治疗后生物力学中位移和 兔肘关节尺侧副韧带急性损伤手术与非 手术治疗后生物力学中位移和 [真诚为您服务] 作者:杨路德，张先龙，王以进，席平昌，高生 【摘要】 ,目的,比较兔急性肘关节尺侧副韧带损伤后手术修复与非手术治疗的 差异。,方法,选取新西兰兔81只，随机分为3组，27只暴露出右尺侧副韧带 后，但不切断，作为正常对照组(A);27只为切断右肘尺侧副韧带后随即缝合韧 带，称为韧带缝合组(B);27只切断尺侧副韧带后不缝合，称为韧带不缝合组 (C)。分别在术后3、6、12周三个阶段取材，进行生物力学检测。,结果,术后 12周，韧带缝合组断裂时的位移与不缝合组比较，差别有统计学意义,B(6. 06?0. 44)mm，C(7. 72?0. 44) mm，P<0. 05,;缝合组位移接近正常 组，差别无统计学意义,A(5. 87?0. 46)mm，P>0. 05,;韧带缝合组应变率 与不缝合组比较，差别有统计学意义\[B(1. 25?0. 16)，C(1. 60?0. 07)，P<0. 05\]，亦与正常组相近\[A(1. 19?0. 13)，P>0. 05\]。,结 论,肘关节尺侧副韧带急性损伤后手术治疗明显优于非手术治疗。 【关键词】 肘关节; 尺侧副韧带; 手术修复; 非手术修复; 生物力学 Abstract:,Objective,To compare the effect of surgical damnification of the ulnar collateral ligaments of elbow joint of the rabbits.,Method, ulnar collateral ligaments of right elbow joint were only enclosed,they were named group A,27 ulnar collateral ligaments of right elbow joint were severed and sutured,the ligaments sutured group were named group B,27 ulnar collateral ligaments of right elbow joint were severed ,they weren't sutured yet,they were named group C.They were killed to detect the biomechanics at time intervals of three,six and twelve weeks.,Result,On the day of 12 week after transplantation,the displacement of the ligaments was significantly different between group B and C ,B ( 6.06?0.4) mm,C ( 7.72?0.44) mm,P<0.05,,and near to the normal control group A ,A (5.87?0.46)mm,P>0.05,.The straining of the ligaments had significant difference between group B and C[B(1.25?0.16),C(1.60?0.07),P<0.05],and also near to the group A[A(1.19?0.13),P>0.05].,Conclusion, The effect of the surgical operation is more effective than the ulnar collateral ligaments of elbow joint.
