ABSTRACT

Osteoarthritis and osteochondrosis are highly correlated to reproductive failure in bulls. This study aimed to evaluate the carpal, tarsal and interphalangeal lesions in beef zebu bulls on semen collection regimen. Twenty-one beef cattle bulls, in a total of forty-one animals, were split into three age-based groups: animals from two to four years old (GI), from more than four to eight years old (GII) and above eight years old (GIII). The clinical findings were conformational changes of limbs, synovial effusion, peripheral venous engorgement of joints and prolonged decubitus. The total population showed moderate clinical manifestation and radiographic score. The GIII presented more severe joint lesions. Carpi and tarsi regions had discrete to difuse osteophytosis, subchondral cysts, cartilaginous flaps, bone incongruence and fragmentation, osteitis, and ankylosis. Interphalangeal joints presented osteophytosis, distal phalanx osteitis and enthesophytosis. The digital radiographic examination allowed full identification of articular lesions and their clinical correspondences, besides the positive correlation between age, body weight and radiographic score.(AU)


Osteoartrite e osteocondrose estão altamente correlacionados à falha reprodutiva em touros. Este estudo teve como objetivo avaliar as lesões do carpo, tarso e interfalangianas em touros zebuínos de corte em regime de coleta de sêmen. Vinte e um bovinos de corte, touros, provenientes de um total de 41 animais, foram divididos em três grupos baseados na idade, sendo eles: animais de dois a quatro anos (GI), de mais de quatro a oito anos (GII) e acima de oito anos de idade (GIII). Os sinais clínicos encontrados foram mudanças de conformação dos membros, derrame sinovial, ingurgitamento venoso periférico das articulações e decúbito prolongado. A população total avaliada apresentou manifestação clínica e escore radiográfico de grau moderado. Os touros mais velhos apresentaram maior gravidade nas lesões articulares. O GIII foi o que apresentou as lesões articulares mais severas. Identificou-se nos carpos osteofitose de discreta a difusa, cistos subcondrais, "flaps" cartilaginosos, fragmentação óssea, perda de congruência óssea, osteíte e anquilose; as lesões társicas obedeceram ao mesmo padrão. As articulações interfalangeanas apresentaram somente osteofitose, osteíte nas falanges distais e entesiofitose. O exame radiográfico digital permitiu a identificação completa das lesões articulares e suas correspondências clínicas, além da correlação positiva entre a idade, o peso corporal e o escore radiológico.(AU)

ABSTRACT

The current study has been achieved to be an essential resource for all veterinary practitioners that deal with the anatomy of the carpal joint of the donkey. Ten adult donkeys of both sexes were used in the current study. The topographical approach to the carpal joint was investigated in this study. Radiography and computed tomography (CT) of the carpus delineated the articulations of the carpal joint: radiocarpal, intercarpal, and carpometacarpal. The carpal ligaments were well delineated and the carpal canal was demonstrated with its content such as superficial digital flexor tendon (SDFT) and deep digital flexor tendon (DDFT). The contrast radiography visualized that the radiocarpal joint outpouched proximal to the accessory carpal bone by large palmarolateral pouch and small palmaromedial pouch, however the intercarpal joint outpouched distal to the accessory carpal bone by two small palmarolateral and palmaromedial pouches. The carpometacarpal joint showed medial and lateral palmarodistal outpouchings in distal direction between the corresponding 2nd and 4th metacarpal bones and the 3rd metacarpal bone. Scanning electron microscopy (SEM) displayed two types of synoviocytes macrophages type A cells and fibroblast like type B cells at the cellular lining of the synovial membrane of the joint capsule.


Este estudio constituye un recurso esencial para todos los veterinarios que se ocupan de la anatomía de la articulación del carpo del asno. Fueron utilizados diez asnos adultos, de ambos sexos. Se analizó la articulación del carpo desde un enfoque topográfico. Se realizaron estudios por radiografía y tomografía computarizada para identificar las articulaciones del carpo en su conjunto: radiocarpiana, intercarpiana y carpometacarpiana. Los ligamentos del carpo se encontraron bien delineados y en el canal carpiano se identificó su contenido, como el tendón del flexor digital superficial y el tendón del flexor digital profundo. La radiografía de contraste permitió visualizar que la articulación radiocarpiana se articula proximalmente con el hueso accesorio del carpo a través una larga evaginación palmarolateral y una pequeña evaginación palmaromedial; sin embargo, la articulación intercarpiana se relaciona distalmente con el hueso accesorio del carpo por medio de dos pequeñas evaginaciones, palmarolateral y palmaromedial. La articulación carpometacarpiana mostró evaginaciones palmarodistales, medial y lateral, en dirección distal entre los correspondiente 2 y 4 huesos metacarpianos y el 3 hueso metacarpiano. La microscopía electrónica de barrido muestra dos tipos de células: células A, correspondientes a sinoviocitos macrófagos y células B, correspondientes a fibroblastos, en el revestimiento celular de la membrana sinovial de la cápsula articular.
