- Osteolysis around uncemented cups is a major complication for THA. We present a 14-year follow-up of 48 hips previously randomized to four groups of cup fixation – sealed cups with press-fit only, cups with hydroxyapatite coating, cups with screws, and cups with pegs. CT scans revealed three types of osteolytic lesions – Type 1A (absence of trabecular bone and a sclerotic border), Type 1B (absence of trabecular bone without a sclerotic border), and Type 2 (reductions in radiodensity and trabeculae). Cups with screw-holes were surrounded with larger osteolytic lesions that were predominantly Type 1A. Unsealed screw holes in uncemented cups appeared to be a risk factor for osteolysis development. Modern CT scans reveal three types of osteolytic lesions. Distinction between types is important for comparability between studies.
