Diagnosis- It takes a long time for the bony changes to be visible on plain x rays.

MRI scans and nuclear bone scans reveal the diagnosis early on when the condition is suspected. Both hips need to be imaged simultaneously. CT scans help to identify the extent of the bony involvement.


The treatment depends on the stage of the disease. Most often conservative or non operative measures fail. Surgical treatment ranges from core drilling to total hip replacements. In the early stages core drilling can lead to a positive result in a good proportion of cases.

When this has failed, or the stage is more advanced, hip resurfacing is advised. However the surgeon should do so after a diligent assessment of the extent of disease. Hip resurfacing can be done when the extent of the femoral head involvement is less than 30 percent.  Presence of cysts,  small size of the head are not the right indication for a hip resurfacing. A short stem hip replacement is a better choice. It is most suited for young patients as it sacrifices very little bone from the top of the femur.

The presence of cysts makes hip resurfacing more difficult to perform with confidence. In these cases there are two options. The Short stem hip replacement is one option.

where the bone is amputated at the base of the head.  Then a short stem is impacted into the top portion or Proximal part of the neck and metaphysis of the femur.

The other option is the Mid head resection Birmingham hip or BMHR.
