背景:马腰病理学数据在纯种马以外的其他品种中几乎不存在。
目的:描述Warmblood马骨腰椎脊柱的病理变化,设得兰群岛小马和Konik马。
方法:描述性验尸研究。
方法:34匹暖血马的腰椎柱,28设得兰群岛小马,并通过计算机断层扫描(CT)检查了18匹Konik马。骨关节炎(OA)的关节突(APJs),横向间关节(ITJ)的OA,椎间盘(IVD)矿化,对棘突(SP)和横突(TP)的撞击和脊椎病进行评分。通过线性回归分析和计算Spearman的等级相关系数(rs)分析了疾病的患病率和严重程度的品种差异。
结果:在暖血马中,APJs的OA患病率,SP和TP的冲击分别为90%,36%,35%,显著高于其他品种(p<0.001)。在Konik马中,IVD矿化(40%)和脊椎病(10%)比Warmbloods和设得兰小马更频繁(p=0.03)。在设得兰群岛小马中,ITJ的OA严重程度得分最高(p<0.001)。对于SP的冲击,Warmbloods的严重程度评分最高(p=0.03),设得兰群岛小马的TP最低(p=0.003)。对于所有参数,除了设得兰小马的脊椎病,受影响的椎骨百分比与年龄呈正相关,Konik马的IVD矿化分数增加更快(p<0.001)。在所有品种中,APJ和ITJ的OA和IVD矿化的严重程度和年龄之间也存在正相关关系,设得兰群岛小马的严重程度评分增加更快(p=0.04)。APJ的OA严重程度评分的左/右相关性很强,ITJ,TP的冲击,和副轴性颈椎病(rs=0.74-0.86,均p<0.001)。
结论:没有临床病史。
结论:腰椎骨性病变的患病率和严重程度之间存在明显的品种差异。温暖的马在大多数病理中得分较高,IVD矿化在Konik马中更为重要,而设得兰小马中ITJ的OA更为重要。
BACKGROUND: Data on equine lumbar pathology hardly exist in breeds other than Thoroughbreds.
OBJECTIVE: To describe pathological changes of the osseous lumbar vertebral column in Warmblood horses, Shetland ponies and Konik horses.
METHODS: Descriptive post-mortem
study.
METHODS: The lumbar vertebral columns of 34 Warmblood horses, 28 Shetland ponies, and 18 Konik horses were examined by computed tomography (CT). Osteoarthritis (OA) of articular processes (APJs), OA of intertransverse joints (ITJs), intervertebral disc (IVD) mineralisation,
impingement of spinous (SPs) and transverse (TPs) processes and spondylosis were scored. Breed differences in prevalence and severity of pathologies were analysed by linear regression analysis and by calculating Spearman\'s rank correlation coefficients (rs).
RESULTS: In Warmblood horses, the prevalence of OA of APJs,
impingement of SPs and TPs was respectively 90%, 36%, and 35%, significantly higher than in the other breeds (p < 0.001). In Konik horses, IVD mineralisation (40%) and spondylosis (10%) were more frequent than in Warmbloods and Shetland ponies (p = 0.03). Severity score for OA of ITJs was highest in Shetland ponies (p < 0.001). For
impingement of SPs, severity score was highest in Warmbloods (p = 0.03), and of TPs lowest in Shetland ponies (p = 0.003). For all parameters, except for spondylosis in Shetland ponies, there was a positive correlation between percentage of vertebrae affected and age, with IVD mineralisation scores increasing faster in Konik horses (p < 0.001). In all breeds, there was also a positive relation between scores of severity and age for OA of APJs and ITJs and for IVD mineralisation, with severity scores increasing faster in Shetland ponies (p = 0.04). Strong left/right correlations of the severity scores were seen for OA of the APJ, ITJ,
impingement of TPs, and paramedian spondylosis (rs = 0.74-0.86, all p < 0.001).
CONCLUSIONS: Clinical histories were not available.
CONCLUSIONS: There are distinct breed differences between prevalence and severity of osseous pathologies of the lumbar spine. Warmblood horses have higher scores for most pathologies with IVD mineralisation being more important in Konik horses and OA of ITJs in Shetland ponies.
