Advances in acetabular osteolysis: biomarkers, imaging, and pharmacologic management.

Acetabular osteolysis can be difficult to diagnose because patients often have no clinical symptoms even when there is substantial bone loss. Ideally, early detection would lead to early interventions. Imaging continues to be the frontline modality for the early detection of acetabular osteolysis. Although plain radiography is the current imaging modality most commonly used in routine follow-up examinations, its low sensitivity limits its usefulness. CT and MRI have proven to be better imaging modalities for the early detection of osteolysis; however, their use is limited by cost, radiation exposure, and time. Biomarkers hold promise for the early detection of osteolysis; however, their efficacy requires more rigorous research for validation. Early diagnosis and treatment of osteolysis may lead to better outcomes for patients.
