HIP DYSPLASIA (HD)

(has been diagnosed infrequently in Australia)


Hip Dysplasia appears to be rare in the Basenji breed, but has occurred. HD is a disease that affects development of the hip joint in a young dog. It may or may not affect both the right and left hip joints. It is brought about by a laxity of the muscles, connective tissue and ligaments that should support the joint.
Dysplastic dogs are born with normal hips but the soft tissues that surround the joint start to develop abnormally as the puppy grows. This is because of genetic factors in the individual dog. The most important result of the change is that the two bones are not held in place but actually move apart. the joint capsule and the ligament between the two bones also stretch, adding further instability to the joint. As this happens, the articular surfaces of the two bones lose contact with each other. The slight separation of the bones of the joint is called subluxation; this and this alone - causes all the resulting problems we associate with the disease.

Radiography is the accepted means for evaluating the hip status, and it is recommended that all breeding stock be tested after maturity and prior to breeding.
