The hock of a greyhound containing a titanium alloy central tarsal replacement was examined histologically. The animal had raced competitively 43 times before retirement. The examination showed that the adaptation and encapsulation of the implant by the surrounding bones, together with the excellent purchase of the screw into the fourth tarsal bone, had maintained the implant in excellent position during vigorous load-bearing. There was no histopathological evidence to suggest that the fixation of the implant was failing. The results provide evidence for the value of titanium alloy implants as a central tarsal replacement in greyhounds with type V fractures, and as a feasible alternative to euthanasia.
对一只装有钛合金中央跗骨替代物的灵缇犬的跗关节进行了组织学检查。这只动物在退役前参加了43次比赛。检查表明，植入物被周围骨骼适应和包裹，以及螺钉在第四跗骨中良好的固定，使得植入物在剧烈负重时保持在良好的位置。没有组织病理学证据表明植入物的固定出现松动。这些结果为钛合金植入物作为V型骨折灵缇犬中央跗骨替代物的价值提供了证据，并且是安乐死的一种可行替代方案。
