A palavra "universidade", partindo do seu conceito léxico, vem do latim "universitas", relacionado ao "conjunto, universidade, comunidade", sabe-se ainda que seu conceito tem origem da expressão -"Universitas magistrorum et scholarium"comunidade de mestres e estudantes ligados pela mesma escola e mesmos interesses culturais (CARVALHO, 1989).A Lei de nº 9.394/96, a qual regulamenta as Diretrizes e Bases da Educação (LDB) nacional define, em seu artigo 52, que as Universidades são "instituições pluridisciplinares de formação dos quadros profissionais de nível superior, de pesquisa, de extensão e de domínio e cultivo do saber humano", caracterizadas pela "produção intelectual institucionalizada mediante o estudo sistemático dos temas e problemas mais relevantes, tanto do ponto de vista científico e cultural, quanto regional e nacional".

Background: Soft tissue injuries are common in sport horses, especially those involving tendons, with few current reports in the literature on the diagnosis of extensor injuries, especially with regard to ultrasound characteristics, being essential for the 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 seen at 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 away from the sport before the onset of the problem, with injuries to the extensor tendons in the radiocarpal region. Two of the animals 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, septic tenosynovitis 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. Bone alteration in the radiographic examination was observed in two cases, however, one of them related to another disease in the radiocarpal palmar region. Ultrasound images, performed in all cases, showed different characteristics and degrees of the involvement of the tendon and its sheath.Discussion: The scarcity of current reports of extensor tendon injuries in horses can be attributed to the fact that they do not suffer as much overload or effect from biomechanics compared to flexor tendons, in addition to being an area of little soft tissue covering these tendons. Although the involvement of the extensor tendons is more frequent in the pelvic limbs, due to lacerations, the occurrence of lesions in the dorsal radiocarpal region may be related to excess flexion, being easily susceptible to trauma to solid objects. The specific clinical examination, associated with a well-explored anamnesis, can allow us to locate the lesion and achieve a presumptive diagnosis. In three cases, tendon injuries were noticeable on inspection and palpation, important points to guide the diagnosis. However, in two cases with associated injuries this perception became difficult. Regardless of the clinical diagnosis, imaging diagnosis in lesions of the locomotor system was essential, as it allowed us to assess bone involvement, accurately determine the location of the lesion, its extent and prognosis, which would not be possible only in the clinic. Through ultrasonography it was possible to classify the lesions into acute (hypoechoic areas) and chronic (hyperechoic areas or with heterogeneous pattern of variable echogenicity), in addition to the thickness and characteristic of the liquid in the tendon sheath, which are also important aspects for lesion classification. Thus, we conclude that the dorsal region at the carpal level is susceptible to trauma and can easily compromise the extensor tendons. And for the diagnosis and adequate conduct, it is necessary to determine ultrasound image regarding the different types of lesions, which is provided in the present study.
