ACETABULAR ANATOMY DETERMINES THE USE OF SCREWS TO AUGMENT FIXATION IN CEMENTLESS CUPS

Acetabular bone structure is not the same in all patients and can be defined by the radiolucent triangle superior to the acetabulum. We ask if the acetabular anatomy determines the initial cup fixation and screws use. null We have assessed 205 hips in which a Cerafit cementless cup was implanted.
