Abstract

The purpose of this study was to describe and assess the feasibility of a new intra-articular approach in the treatment of cranial cruciate ligament deficiency in dogs using an artificial ligament and a new bone-anchor system. Twelve canine cadavers weighting 26 to 45 kg were used in this ex-vivo study. Special tibial and femoral screws, two helicoils, and a high resistance artificial fiber compose the implant. Surgery was performed using the cranio-lateral approach to the stifle joint. Helicoil and tibial screw, connected to the fiber, were inserted in the center of the tibial insertion area of the cranial cruciate ligament. The fiber was passed over-the-top, tensioned, and fixed to the femoral screw, previously inserted with the helicoil in the distal part of the femur. Surgery was completed in all the cases. Occasional problems found during the insertion of the helicoils and screws were resolved with simple procedures. Post-operative clinical assessment showed negative cranial drawer test, negative cranial tibial thrust, and normal range of motion. Radiographic evaluation showed an appropriate positioning of both tibial and femoral implants in all the cases. The results of the first surgical appraisal of this new technique are encouraging, although further studies are necessary to demonstrate the in vivo efficacy of this procedure.

摘要

本研究的目的是描述并评估一种新的关节内入路,该入路使用人工韧带和新型骨锚系统治疗犬颅交叉韧带缺损的可行性。本体外研究使用了12只体重在26至45千克之间的犬类尸体。植入物由特殊的胫骨和股骨螺钉、两个螺旋线圈以及高强度人工纤维组成。手术采用颅外侧入路至膝关节。将与纤维相连的螺旋线圈和胫骨螺钉插入颅交叉韧带胫骨插入区域的中心。纤维从上方穿过,张紧并固定在股骨螺钉上,股骨螺钉先前已与螺旋线圈一起插入股骨远端。所有病例的手术均完成。在插入螺旋线圈和螺钉过程中偶尔出现的问题通过简单的操作得以解决。术后临床评估显示颅侧抽屉试验为阴性、颅侧胫骨推力为阴性且活动范围正常。影像学评估显示所有病例中胫骨和股骨植入物的位置均合适。尽管需要进一步研究以证明该手术在体内的疗效,但这项新技术的首次手术评估结果令人鼓舞。
