The relative incidence of dorsal metacarpal disease was examined in two groups of Thoroughbred racehorses training on dissimilar surfaces (dirt and wood fibre). The horses and training methods appeared to be similar. The incidence of disease was significantly greater in the group training on dirt. There was no significant difference in the age distribution of incidence between the two groups and there was no association of incidence with sex or age within the training group. The number of fast miles worked by the two groups prior to the onset of dorsal metacarpal disease was lower in the group training on dirt.
在两组于不同地面（泥土和木纤维）上训练的纯种赛马中，对掌背疾病的相对发病率进行了检查。马匹和训练方法似乎相似。在泥土上训练的那组中疾病发病率显著更高。两组发病率的年龄分布没有显著差异，且在训练组内发病率与性别或年龄均无关联。在掌背疾病发作前，在泥土上训练的那组马匹所完成的快速英里数较少。
