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
