To describe the MRI findings for 13 horses with deep digital flexor tendon (DDFT) injury at the proximal phalanx where the tendon goes from ovoid to bilobed in frontlimbs with tendon sheath distension. In addition, the prognosis of this lesion was assessed. Retrospective case series. Thirteen client-owned horses. Medical records were reviewed, and data were collected regarding signalment, history, MRI findings, and outcomes of horses. Findings of MRI were recorded and whether the case was confirmed with tenoscopy. A diagnosis of DDFT injury at the junction between ovoid and bilobed portions at the level of the proximal phalanx was established in 13/20 (65%) horses that underwent MRI examination of the frontlimb digital flexor tendon sheath. Return to previous level of work was poor in this subset of horses with only three of 13 (23%) horses returning to previous level of work and one horse still in rehabilitation. Standing low-field MRI represents a potentially useful diagnostic tool to evaluate digital flexor tendon sheath distension especially when evaluating the DDFT at the proximal phalanx where the tendon progresses from ovoid to bilobed. Prognosis of lesions of the DDFT at the proximal phalanx appears less favorable than previously reported causes of tendon sheath distension.
描述13匹前肢深屈肌腱（DDFT）在近节指骨处损伤的马匹的MRI表现，此处肌腱从椭圆形变为双叶形，并伴有腱鞘扩张。此外，评估了该病变的预后。回顾性病例系列研究。13匹客户拥有的马匹。查阅病历，收集有关马匹的特征、病史、MRI表现和结局的数据。记录MRI检查结果以及病例是否通过腱鞘镜检查确诊。在接受前肢指屈肌腱鞘MRI检查的20匹马中，有13匹（65%）被诊断为近节指骨水平椭圆形与双叶形交界处的DDFT损伤。在这组马匹中，恢复到先前工作水平的情况较差，13匹马中只有3匹（23%）恢复到先前工作水平，1匹马仍在康复中。站立式低场MRI是评估指屈肌腱鞘扩张的一种潜在有用的诊断工具，尤其是在评估近节指骨处肌腱从椭圆形变为双叶形的DDFT时。近节指骨处DDFT病变的预后似乎比先前报道的腱鞘扩张原因更不理想。
