Abstract

Objective The aim of this retrospective multicentre case series was to describe signalment, presenting signs and imaging findings in dogs with isolated articular fractures of the talus.

Study Design Medical records (2008–2019) of dogs with isolated articular talar fractures were reviewed.

Results Fourteen dogs met the inclusion criteria; affected breeds were four German Pointer (three shorthair and one wirehaired), three Labrador Retrievers, two Rottweilers, two Springer Spaniels, one cross breed, one Greyhound and one Great Münsterländer. The age range was 1 to 8 years with a median of 4.7 years. Lameness was usually acute in onset and had been present for a range of 4 to 540 days prior to referral.

The most common fracture configuration involved the lateral trochlear ridge only (n = 9). Two of the fourteen fractures affected both trochlear ridges. Thirteen dogs were initially assessed radiographically with classic orthogonal views, but a fracture was only visible in five cases. The remainder were confirmed with further radiographic projections (n = 4) or computed tomography (n = 5). In one case, the lameness was located to the tarsus by scintigraphy.

Conclusion Isolated articular fracture of the talus is rare and may prove a diagnostic challenge due to the varied presentations and complex anatomy of the bone. Pathology of the talus may be suspected in any case of lameness localized to the tarsus and oblique/skyline radiographic views or advanced imaging should be performed if standard radiographic views are unremarkable.

犬距骨孤立性关节骨折：14 只犬的诊断和信号

摘要

目的 本回顾性多中心病例系列的目的是描述孤立性距骨关节骨折犬的信号、表现体征和影像学发现。

研究设计 回顾了患有孤立性关节距骨骨折的犬的医疗记录（2008-2019 年）。

结果 符合纳入标准的犬14只；受影响的品种是四只德国指针犬（三只短毛犬和一只硬毛犬）、三只拉布拉多猎犬、两只罗威纳犬、两只史宾格犬、一只杂交犬、一只灵缇犬和一只大明斯特兰德犬。年龄范围为 1 至 8 岁，中位数为 4.7 岁。跛行通常是急性发作，并且在转诊前已经存在 4 至 540 天。

最常见的骨折形态仅涉及外侧滑车脊（n  = 9）。14 处骨折中的 2 处影响了两个滑车脊。最初用经典的正交视图对 13 只狗进行了放射学评估，但只有 5 例可见骨折。其余的通过进一步的放射照相投影 ( n  = 4) 或计算机断层扫描 ( n  = 5)得到证实。在一个案例中，跛行通过闪烁扫描定位到跗骨。

结论 距骨孤立性关节骨折很少见，由于骨骼的不同表现和复杂的解剖结构，这可能是诊断方面的挑战。在任何跛行跛行的情况下，都可能怀疑距骨的病理学，如果标准的 X 线片没有异常，则应进行斜线/天际线 X 线片检查或高级成像。
