为了探索人工圆韧带植入术治疗犬髋关节脱位远期疗效降低的解决办法，选择体重6．5 kg～7．5 kg、年龄1岁左右的3只本地家犬，在使用外科丝线替代圆韧带植入髋关节后，使用医用骨水泥填充和封闭髋臼和股骨孔道，术后通过运动姿态观察、负重力测试、常规 X 线摄片、血清生化项目检测和病理剖检几个方面，分析评估人工圆韧带植入术使用医用骨水泥的效果。结果显示，随着犬肢运动状态逐渐改善，术肢负重力增加；但随着丝线断开或出现退行性关节病，术肢运动肢势改变和负重力降低；骨水泥填充、封闭人工圆韧带孔道效果可靠，关节滑液保持良好，血清重要生化指标均在参考范围。在动物试验基础上，选择医用人工韧带植入和将骨水泥用于犬髋关节脱位临床病例1例，经过9个月的动态观察，术肢运动状态、负重力和髋关节 X 线影像与健肢相比无任何异常。动物试验与临床疗效表明，联合使用医用骨水泥和人工韧带能够很好地重建髋关节结构和功能，维持人工圆韧带植入术治疗犬髋关节脱位的远期疗效。%To explore the solution for the lower long-term effects of the ligamentum teres implantation for canine hip joint dislocation,three hybrid dogs of about 1 year old,6.5 kg~7.5 kg body weight were select-ed.After surgical silk thread instead of the ligamentum teres was implanted into a hip joint,the acetabular and femoral holes were filled and closed with medical bone cement.Effect of the bone cement was analysed and evaluated by the observation of motion state,weight-bearing gravity test,conventional X-ray radio-graph,detection of serum biochemical items and pathological dissection.The results showed that the limb weight-bearing gravity increased with motion state gradually improved.But as the silk thread was discon-nected or degenerative joint disease appeared,the limb motion gesture was not good and weight-bearing gravity reduced.The effect of bone cement filling and closing artificial ligamentum teres pores is reliable, and serum biochemical items in the reference range.On the basis of animal experiments,an medical artifi-cial ligament and bone cement were used to a case dog′s right dislocated hip joint.During the period of dy-namic observation for 9 months,the limb motion posture,weight-bearing gravity and hip X-ray image were exactly the same as another healthy limb.The animal experiments and the clinical curative effects showed that combined use of the medical bone cement and the artificial ligament can well reconstruct the hip joint structure and function,and effectively maintain the long-term curative effect of artificial ligament implantation for canine hip joint dislocation.
