Navicular syndrome is a multifactorial disease process in horses with multiple structures in the foot contributing to lameness. Surgical debridement is a treatment option for lesions of the navicular bursa and deep digital flexor tendon. This retrospective case series describes the magnetic resonance imaging (MRI) appearance of the navicular bursa following bursoscopy. Seven horses (three being bilaterally affected) with forelimb lameness isolated to the foot, and pre- and post-operative MRI were included. All limbs had concurrent lesions associated with the deep digital flexor tendon, navicular bone, impar ligament, collateral sesamoidean ligament and/or distal interphalangeal joint. All bursae developed or had progression of proliferative bursal tissue following surgery. At recheck MRI, following rehabilitation protocols, almost all horses had improved to resolved lameness with relatively unchanged concurrent lesions despite the navicular bursa appearance worsening. Outcomes for return to work were poor with only two horses going back to the previous level of work.

七匹马的舟状囊镜检查后舟状囊的磁共振成像变化

舟状综合征是马的多因素疾病过程，马的脚部有多个结构，导致跛行。手术清创术是治疗舟状囊和深趾屈肌腱损伤的一种选择。这个回顾性病例系列描述了滑囊镜检查后舟状滑囊的磁共振成像 (MRI) 表现。包括前肢跛行的七匹马（三匹双侧受累），以及术前和术后的 MRI。所有四肢都有与深部屈肌腱、舟骨、截骨韧带、副籽韧带和/或远端指间关节相关的并发病变。手术后所有法氏囊都出现增生性法氏囊组织或有增生性法氏囊组织进展。在复查 MRI 时，遵循康复方案，尽管舟状囊外观恶化，但几乎所有的马都改善了跛行，同时病变相对不变。重返工作的结果很差，只有两匹马回到了以前的工作水平。
