Abstract

Osteoarthritis (OA) of the distal interphalangeal joint (DIPJ) can significantly affect horse performance and overall health. This article discusses three cases of a rare form of OA in the DIPJ, involving the palmar distal condyles of the middle phalanx and the dorsal articular surface of the navicular bone, as seen on MRI. Lesions of the flexor fibrocartilage surface of the navicular bone have been described in the literature; however, focal hyaline cartilage loss from the opposite articular surfaces of the navicular bone and the middle phalanx has not been reported as a manifestation of OA in the DIPJ. The loss of hyaline cartilage from this location has been clearly defined on MRI images, confirming that standing low-field MRI is an accurate diagnostic tool for identifying this type of OA in the DIPJ. This condition has a poor prognosis for athletic performance as none of the horses described in this report resumed their previous athletic activity, despite several conservative and/or surgical treatments.

三匹温血马远端指间关节骨关节炎的磁共振成像表现

骨关节炎（OA）的远端指间关节（DIPJ）可以显著影响马的表现和整体健康。这篇文章讨论了三例罕见形式的骨关节炎在DIPJ，涉及掌远端髁的中指骨和舟骨的背关节面，从MRI上看。舟骨屈肌纤维软骨表面的病变已经在文献中描述过；然而，从舟骨和中指骨的相对关节面出现局灶性透明软骨丢失尚未被报道为DIPJ骨性关节炎的表现。该部位透明软骨的缺失在MRI图像上已被明确定义，证实静置低场MRI是识别DIPJ中此类OA的准确诊断工具。这种情况对运动表现的预后很差，因为尽管进行了一些保守和/或手术治疗，但本报告中描述的马都没有恢复以前的运动活动。

期刊介绍： Equine Veterinary Education (EVE) is the official journal of post-graduate education of both the British Equine Veterinary Association (BEVA) and the American Association of Equine Practitioners (AAEP). Equine Veterinary Education is a monthly, peer-reviewed, subscription-based journal, integrating clinical research papers, review articles and case reports from international sources, covering all aspects of medicine and surgery relating to equids. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of equine medicine and surgery. The educational value of a submitted article is one of the most important criteria that are assessed when deciding whether to accept it for publication. Articles do not necessarily need to contain original or novel information but we welcome submission of this material. The educational value of an article may relate to articles published with it (e.g. a Case Report may not have direct educational value but an associated Clinical Commentary or Review Article published alongside it will enhance the educational value).
