The muscle groups involved in the hip joint do not attach to thehead or neck of the femur, so they aren't disturbed by its removal. Also, these muscle groupsare very large and strong, so they are able to stabilize the area themselves. Lastly, because thisis mostly a problem in toy breed dogs, the hip does not bear a large amount of weight.

Cage rest is an alternative to surgery that may be used in a small number of dogs affected by Legg-Calve-Perthes disease. The only time this treatment is a possibility is when, as viewed on an X-ray, the hip joint still has its proper shape, and the cartilage is still smooth.

Because no harm occurred to the cartilage or the shape of the hip joint, the dogs is able to resume normal activities at this point, without pain.

The downfall of cage rest for treating Legg-Calve-Perthes disease is that the dog must be confined to a cage for, usually, four to six months. This disease affects puppies, and it can be difficult and heart-breaking to prevent them from running and playing for such a long period of time.
