To determine clinical signs, radiographic and scintigraphic findings, and performance outcome of racing Standardbreds with tibial stress fractures.
Retrospective case series.
13 racing Standardbreds with tibial stress fractures.
Information concerning clinical signs, diagnostic evaluation, and recommendations was obtained by review of the medical records. Performance information before and after diagnosis of the fracture was collected from racing records, and follow-up information was obtained from the owners or trainers by use of a telephone questionnaire.
Horses with tibial stress fractures were moderately lame, and diagnosis was made by nuclear scintigraphy and radiography. Fractures were more likely to occur in 2-year-old horses than in older horses. The fracture location was unique for Standardbreds; 11 of 13 developed stress fractures in the mid-diaphysis of the tibia, whereas fractures in Thoroughbreds are usually in the proximal caudal or caudolateral cortex. Fractures occurred in young horses that had raced or were in advanced race training. All horses were treated with rest alone, and 10 of 13 horses raced after injury. The horses that raced after injury were able to return to a level of performance that was equal to or better than the level raced before injury. 8 of 10 horses established a lifetime-best winning time after injury.
Tibial stress fractures are a cause of lameness in young racing Standardbreds. Diagnosis is aided by nuclear scintigraphy. The prognosis for return to previous level of performance after a tibial stress fracture is good.
确定患有胫骨应力性骨折的比赛用标准赛马的临床体征、影像学和闪烁显像结果以及运动表现结果。
回顾性病例系列研究。
13匹患有胫骨应力性骨折的比赛用标准赛马。
通过查阅病历获取有关临床体征、诊断评估和建议的信息。从比赛记录中收集骨折诊断前后的运动表现信息，并通过电话问卷从马主或训练师处获取随访信息。
患有胫骨应力性骨折的马匹中度跛行，通过核闪烁显像和X线摄影进行诊断。骨折在2岁马中比在年龄较大的马中更易发生。标准赛马的骨折部位具有独特性；13匹马中有11匹在胫骨骨干中部发生应力性骨折，而纯种马的骨折通常发生在近端尾侧或尾外侧皮质。骨折发生在已参赛或处于高级比赛训练阶段的年轻马匹中。所有马匹均仅接受休息治疗，13匹马中有10匹在受伤后继续参赛。受伤后参赛的马匹能够恢复到与受伤前相当或更好的运动水平。10匹马中有8匹在受伤后创造了一生最佳的获胜时间。
胫骨应力性骨折是年轻比赛用标准赛马跛行的一个原因。核闪烁显像有助于诊断。胫骨应力性骨折后恢复到先前运动水平的预后良好。
