Retroacetabular osteolysis: when to operate?

abstract：UNLABELLED:Metastatic bone disease of the humerus may require surgery for treatment of an impending or existing pathologic fracture or for alleviating disabling pain. Prompt restoration of function is a main goal of surgery, although published results do not reveal if that goal is being met. We retrospectively reviewed...
