| Abstract | ||
| The ongoing debate about coxo-femoral joint disease in domestic dogs indicates that new research is needed. Affected non-domestic canids are reported occasionally; we examined skeletal remains of a grey wolf and reported our observations. Femurs of this specimen revealed articular margin new bone, mild new bone filling of the dorsal femoral neck, and a diagonal osteophyte line originating from the craniolateral aspect of the articular margin new bone. The latter extended in a cranioventral direction to the proximomedial femoral shaft, possibly representing new bone deposition along the margin of the joint capsule attachment. The features were incon- clusive by radiography. We suggest that some features of domestic dog coxofemoral joint disease may have ancestral origin, further underscoring the need for new research. | ||
