There have been many studies that document radiographic findings in young Thoroughbred and Standardbred horses. No such studies have been performed in Quarter Horses.
To describe the prevalence of radiographic changes in the stifles, tarsi, carpi and fetlocks of young Quarter Horses intended for cutting.
Radiographs of yearling and 2-year-old Quarter Horses were obtained from a radiograph repository and a private farm. The carpi, tarsi, fetlocks and stifles were evaluated and radiographic changes categorised by type and location. The frequency of changes was calculated and comparisons were made between the 2 age groups.
Of 458 included horses, 408 (89.1%) had radiographic changes, most of which were in the tarsi (304, 69.4%) followed by the stifles (202, 44.5%), hind fetlocks (155 of 355, 43.7%), fore fetlocks (131 of 361, 36.3%) and carpi (27 of 342, 7.9%). Of the horses with stifle changes, 188 (93.1%) were in the medial femoral condyle (MFC). There was a significant difference between the age groups for changes on the distal intermediate ridge of the tibia (DIRT), hindlimb middle phalanx (P2) osteophytes and proximal tibial osteophytes.
There is a high prevalence of radiographic changes in presale survey radiographs, especially in the stifles and tarsi, of young Quarter Horses intended for cutting.
Veterinarians examining presale radiographs at cutting horse sales should expect a high prevalence of radiographic changes in this population of horses. Work to determine the clinical relevance of these radiographic changes is currently ongoing.
有许多研究记录了年轻的纯血马和标准马的放射影像学表现。但尚未在夸特马中进行此类研究。
描述用于切割的年轻夸特马的膝关节、跗关节、腕关节和球节的放射影像学变化的发生率。
从放射影像存储库和私人农场获得了一岁和两岁的夸特马的 X 光片。对腕关节、跗关节、球节和膝关节进行评估，并根据类型和位置对放射影像学变化进行分类。计算变化的频率，并比较两个年龄组之间的差异。
在纳入的 458 匹马中，408 匹（89.1%）有放射影像学变化，其中大多数发生在跗关节（304 匹，69.4%），其次是膝关节（202 匹，44.5%）、后球节（355 匹中的 155 匹，43.7%）、前球节（361 匹中的 131 匹，36.3%）和腕关节（342 匹中的 27 匹，7.9%）。在膝关节有变化的马匹中，188 匹（93.1%）发生在股骨内髁（MFC）。胫骨远端中间嵴（DIRT）、后肢中趾骨（P2）骨赘和胫骨近端骨赘的变化在两个年龄组之间存在显著差异。
用于切割的年轻夸特马的售前调查 X 光片中存在很高的放射影像学变化发生率，尤其是在膝关节和跗关节。
在切割马销售中检查售前 X 光片的兽医应该预计在这个马种群中会有很高的放射影像学变化发生率。目前正在努力确定这些放射影像学变化的临床相关性。
