In a retrospective study, 74 horses met defined historical and clinical features indicative of navicular disease. Most of the affected horses were 4 to 9 years old. Males had a greater risk of navicular disease than females, geldings had a greater risk than stallions, and Quarter Horses had a greater risk than other breeds. Diagnostic radiographic changes were found in 42 of 70 horses examined. The distribution of diagnostic radiographic changes between the right and left fron feet was equal. There was no correlation between the finding of diagnostic radiographic changes and the horse's response to therapy or the type of work for which the horse had been used. A questionnaire regarding the current status of the horses in the study was mailed, and 51 replies were received. Of the 38 horses that were alive at least 6 months after treatment and for which the current status was known, 9 were sound at the time of follow-up (from 7 to 91 months after treatment). Three of these horses had been treated medically, 4 surgically, 1 by corrective shoeing, and 1 not treated. No advantage for medical or surgical therapy was demonstrated. The poor response to therapy in this group of horses suggests that the prognosis for horses with navicular disease should be guarded, and that the probability of a return to a prelameness capacity for work is slight.
在一项回顾性研究中，74匹马符合舟状骨疾病的明确病史和临床特征。大多数患病马匹年龄在4至9岁之间。雄性马患舟状骨疾病的风险高于雌性马，去势雄马高于种马，四分之一马种高于其他品种。在接受检查的70匹马中，有42匹马出现了诊断性放射学变化。诊断性放射学变化在右前蹄和左前蹄之间的分布是均等的。诊断性放射学变化的发现与马匹对治疗的反应或马匹所从事工作的类型之间没有相关性。关于研究中马匹当前状况的问卷已邮寄出去，共收到51份回复。在治疗后至少存活6个月且已知当前状况的38匹马中，9匹马在随访时（治疗后7至91个月）状况良好。其中3匹马接受了药物治疗，4匹马接受了手术治疗，1匹马接受了矫正蹄铁治疗，1匹马未接受治疗。未显示出药物治疗或手术治疗有优势。这群马匹对治疗反应不佳表明，舟状骨疾病马匹的预后应谨慎对待，恢复到跛行前工作能力的可能性很小。
