肌腱/韧带矿化在马身上得到了认可，但关于其临床意义的信息有限。这项观察性研究的目的是报告最常见的受超声可检测矿化影响的结构，并为此确定诊断频率和关键临床特征。纳入1999年4月-2013年4月和2014年9月-2015年11月在本院就诊的病例：共27匹(22匹回顾，5匹预期)。矿化最常见的是指深屈肌腱(10例)和悬韧带支(8例)，分别占研究期间诊断为这些结构损伤的马的10%和7%(估计)。指深屈肌腱2例，悬韧带支3例，均显示双侧矿化。指屈肌腱深部矿化局限于指屈肌腱鞘，最常见的是近端鞘(+/-芝麻管)，10例中有7例累及后肢。10/11个肢体的悬韧带支矿化与近端籽骨可见，其中6例累及前肢。既往皮质类固醇药物治疗的特点是指深屈肌腱和悬韧带支各1例。矿化与部分但不是所有肢体的跛行有关。指深屈肌腱内的矿化灶先于双侧肢体形成低回声病变。仅有指深屈肌腱或悬韧带支损伤的病例中，3例中1例痊愈，2例痊愈。研究结果表明，肌腱/韧带矿化可能与某些马的跛行有关，但也可能是偶然发现。
Tendon/ligament mineralization is recognized in horses but information regarding its clinical significance is limited. The aims of this observational study were to report the structures most commonly affected by ultrasonographically detectable mineralization and, for these, determine frequency of diagnosis and key clinical features. Cases presented at our hospital in April 1999-April 2013 and September 2014-November 2015 were included: a total of 27 horses (22 retrospective, five prospective). Mineralizations were most common in deep digital flexor tendons (10) and suspensory ligament branches (eight), representing 10% and 7% (estimated), respectively, of horses diagnosed with injuries to these structures during the study. Two deep digital flexor tendon and three suspensory ligament branch cases showed bilateral mineralization. Deep digital flexor tendon mineralization was restricted to the digital flexor tendon sheath, most commonly in the proximal sheath (+/- sesamoidean canal), and seven of 10 cases involved hindlimbs. Suspensory ligament branch mineralization was visible in the same ultrasound window as the proximal sesamoid bones in 10/11 limbs and six of eight cases involved forelimbs. Previous corticosteroid medication was a feature of one deep digital flexor tendon and one suspensory ligament branch case. Mineralization was associated with lameness in some but not all limbs. Mineralized foci within the deep digital flexor tendon preceded hypoechoic lesion formation in two limbs. Of the cases with deep digital flexor tendon or suspensory ligament branch injury only, one of three and two of three cases, respectively, became sound. Findings indicated that tendon/ligament mineralization can be associated with lameness in some horses, but can also be an incidental finding.
