Static locked nailing was used to repair fractures of the femoral diaphysis in 15 dogs. The implant consists of a 5, 6, or 7 mm diameter stainless steel rod made up of two parts: the body of the nail, in which there are 13 threaded holes, and a piece without holes that contains a slot for anchoring the jig. Good limb function was obtained after less than 3 weeks in 12 dogs and these dogs remained sound throughout the study. Radiographic examination revealed fracture healing in 11 of the dogs, between 8 and 16 weeks after surgery. One dog was not returned for follow-up evaluation until 22 weeks after surgery; complete healing was apparent from radiographic examination. The remaining three dogs had to have additional operations, one because of lameness caused by excessive length of the distal screws, one because of a nonunion, and the third because of a sequestrum. Fracture healing in these dogs was observed at 18, 21, and 24 weeks respectively. Loosening of one screw and angulation of the bone occurred in one dog. These complications had no adverse effects on clinical outcome.
采用静力锁定髓内钉固定法对15只犬的股骨干骨折进行修复。植入物由一根直径为5、6或7毫米的不锈钢棒组成，该不锈钢棒分为两部分：钉体，其上有13个螺纹孔；以及一块无孔的部件，该部件有一个用于固定夹具的槽口。12只犬在不到3周的时间内获得了良好的肢体功能，并且在整个研究过程中保持健康。X线检查显示，11只犬在术后8至16周骨折愈合。一只犬直到术后22周才回来进行随访评估；X线检查显示骨折已完全愈合。其余三只犬需要进行额外的手术，一只犬是因为远端螺钉过长导致跛行，一只犬是因为骨折不愈合，第三只犬是因为死骨形成。分别在18、21和24周观察到这些犬的骨折愈合情况。一只犬出现了一枚螺钉松动和骨成角现象。这些并发症对临床结果没有不利影响。
