Abstract

Nonseptic tenosynovitis (NST) of digital flexor tendon sheath (DFTS) is a common condition in horses, frequently associated with manica flexoria or deep digital flexor tendon tears. Tenosynovitis of the DFTS secondary to proximal sesamoid bones (PSBs) injury is rare. This report described a case of NST of the DFTS caused by an abaxial fracture of lateral PSB in a 7-year-old mare used for showjumping. The mare presented with right hindlimb (RH) lameness following a field accident. Radiographic examination of the RH fetlock revealed an abaxial fracture of the plantarolateral margin of lateral PSB. Ultrasonographic examination confirmed the presence of moderate DFTS effusion with no concurrent intrathecal pathology. Due to the lack of improvement with conservative management, the horse underwent DFTS tenoscopy. During tenoscopy, a tear of the proximolateral aspect of the sheath wall communicating with the fracture bed was found at the junction between the proximal scutum and the plantar annular ligament. The bone fragment was removed and the torn fibres debrided. After 5 months of rehabilitation, the mare returned to the previous level of activity. To the best of the authors' knowledge, this is the first report detailing the management and outcome of DFTS tenosynovitis secondary to PSB fracture.

近端籽状骨骨折是指屈肌腱鞘非感染性腱鞘炎的一个原因

指屈肌腱鞘（DFTS）的非感染性腱鞘炎（NST）是马的一种常见疾病，通常与拇屈肌或深指屈肌腱撕裂有关。摘要腱鞘炎继发于近端籽骨（PSBs）损伤是罕见的。本报告描述了一个7岁的母马参加障碍赛，由外侧PSB背侧骨折引起的DFTS NST病例。母马表现为右后肢（RH）跛行后，现场事故。放射学检查显示外侧PSB的跖外侧缘的下向骨折。超声检查证实存在中度DFTS积液，未并发鞘内病变。由于缺乏保守治疗的改善，马接受了DFTS肌腱镜检查。在肌腱镜检查中，在近端骨痂和足底环韧带交界处发现与骨折床相通的鞘壁近外侧撕裂。骨头碎片被取出，撕裂的纤维被清理。经过5个月的康复，母马恢复到以前的活动水平。据作者所知，这是第一份详细介绍PSB骨折继发的DFTS腱鞘炎的处理和结果的报告。

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).
