Traumatic avulsion of the proximal femoral articular cartilage as a cause of hip dislocation in broiler chickens.
Review of the normal anatomy of the coxofemoral joint in broiler chickens aged seven weeks and comparison with cases of so-called "hip-dislocation" revealed that the lesion is essentially an avulsion of the articular cartilage of the femoral head, traumatically caused by the manner of catching and handling of birds. No direct relationship to dyschondroplasia (osteochondrosis) was established.
