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。[ Objective] To compare the effect of surgical operation and non-operation therapeutical effect of acute damnifica- tion of the ulnar collateral ligaments of elbow joint of the rabbits. [ Method] Eighty-one New Zealand rabbits were randomly divid- ed into 3 groups. Twenty-seven ulnar collateral ligaments of right elbow joint were only enclosed, they were named group A ,27 ul- nar 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 werent sutured yet, they were named group C. They were killed to de- tect 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 ± O. 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 non-operation in deeling with a- cute damnification of the ulnar collateral ligaments of elbow joint.
