The : The acetabulum is the "cup." increased uptake could be caused by loosening, infection or fracture. Talk to your surgeon about it.

Uptake on bone scan: Bone scan after injection of IV radiotracer is sensitive for changes in bone metabolism. Increased uptake is not specific but can be related to infection, fracture, loosening or even tumor. However ct shows anatomy and pathology. The loss of bone can occur from lack of normal weight bearing or disuse. Demineralization around stem of prosthesis can be loosening. You should consult your doctor.
