Background: Soft tissue injuries are common in sport horses, especially those involving tendons, with few current reportsin the literature on the diagnosis of extensor injuries, especially with regard to ultrasound characteristics, being essential forthe diagnosis of these injuries. The objective of the study is to characterize the clinical signs and the alterations of images,especially ultrasound, in the diagnosis of these lesions of the dorsal radiocarpal region, through case reports of horses seenat the Medical Clinic of Large Animals of the Federal University of Campina Grande (MCLA/UFCG), Patos, PB, Brazil.Cases: The study includes five vaquejada competitions horses, of which two were active and the others were awayfrom the sport before the onset of the problem, with injuries to the extensor tendons in the radiocarpal region. Two of theanimals had involvement of the common digital extensor muscle tendon (CDEMT), with acute and chronic tenosynovitis,and three with involvement of the extensor carpi radialis muscle tendon (ECRMT), presenting acute tendonitis, septictenosynovitis and rupture, all of traumatic etiology, except for one whose cause has not been determined. On physical examination, the affected tendon was noticeable in three cases, and two had other injuries associated with the tendons. Bonealteration in the radiographic examination was observed in two cases, however, one of them related to another disease inthe radiocarpal palmar region. Ultrasound images, performed in all cases, showed different characteristics and degrees ofthe involvement of the tendon and its sheath.Discussion: The scarcity of current reports of extensor tendon injuries in horses can...(AU)
