Resumo
Radiographic evaluation has been done lately as important diagnosis
recourse for bovine locomotor injuries. However the scarcity of study in this
area has made difficult the veterinary s performance. The aim of the study was
to use radiographic exams to help in the characterization of the most important
bone injuries that compromise bovine digit, metacarpophalangeal and
metatarsophalangeal joint as well as relate radiographic findings to lameness
sings and the presence of feet injuries. Participate in this study fifty male
bovines (Zebu x European), confined, carrying locomotor alterations, with or
without digital alteration, from the state of Goiás. All the animals were evaluated
about the locomotion score the moment they arrived, and 112 days latter at the
end of the confinement. After the slaughter, the four member distal extremities
were collected (n=200) and evaluated about clinic and radiographic alterations.
Claudication was found out in 86% of the animals. The locomotion scores were
distributed as fallowing: 14% had score 1, 20% score 2, 52% score 3 and 14%
score 4. The comparison between two moments, arrival and end of the
confinement, demonstrated the aggravation of the locomotion score during the
period the animals were confined. Only 29,5% from the extremities evaluated
presented digital injuries. From these, 40,7% were classified as mixture, 32,2%
septic pododermatitis, 11,9% interdigital dermatitis, 8,5% horn erosion and
68% as digital dermatitis. According to the radiographic evaluation 25,5% of the
extremities presented some kind of digital alteration. The main injuries were
distributed in joint degenerative disease (27,5%), osteitis (19,6%), periostitis
(15,7%), septic arthritis in distal interphalangeal joint (11,8%), calcification off
deep flexor tendon (7,8), calcification of the extensor tendon (5,9%), fracture in
chip, ankylosis of joint and calcification of the proximal insertions of the
cruciate ligaments (3,9% each one). The results showed relation between the
presence of lameness and digital injuries with the radiographic alterations
observed in the digits, however this relation was not found in the radiographic
alterations of the fisis from metacarpophalangeal and metatarsophalangeal
joints. We concluded that the locomotion score, associated to characterization of the podal injuries and the radiographic examination, helped in the diagnosis
of lameness and that there is a relation among lameness, pedal injuries and
radiographic alterations. It also showed that the confinement may be a
determinating factor to the development of fiseal dysplasia in bovines, however,
for better comprehension of the illness more radiographic studies that go along
with the animal growth must be carried out
