Hip disorders and treatments

Of 104 lame broilers, 12 birds with femoral trochanteric abnormalities were identified by post-mortem and radiographic examination. Defects occurred in ossification of either the trochanteric zenith or its medial aspect. Lesions were identified as dyschondroplasia, osteochondrosis or osteochondrosis dissecans affecting the articular surface of the femoral trochanter. In the absence of concomitant musculoskeletal disease, degrees of lameness can be attributed to trochanteric lesions. Breaches in the medial trochanteric bone plate permit granulation tissue repair of the articular surface. This repair process, however, did not compensate for the loss of articular surface contour and the junction of reparative and normal tissue may be prone to subsequent degeneration.
