“…Twenty-three hips had only the acetabular component revised and the others had both the acetabular and femoral components revised. Acetabular bone status was ascertained during the operation and the hips were classified according to the Paprosky system [4,20]. Four hips were classified as type 1, 17 as type 2 (2A, 2 hips; 2B, 8 hips; 2C, 7 hips); 10 hips were type 3A.…”

Implant loosening and osteolysis can be associated with massive bone loss. Since the structural quality of bone is difficult to assess accurately with any type of preoperative study, the surgeon needs to be ready to alter the course of the operation based on the circumstances found during surgery and must be prepared with a variety of implants and techniques. We reviewed the results of 88 acetabular revisions performed with the Sph acetabular revision system (Lima-Lto, Italy). This system allows us to choose, during the operation without changing the instrument set, between a hemispherical porous-coated cup, a winged reconstruction ring with an uncemented inner module and a bilobed cup. We implanted 31 Contact, 39 Bicomponente and 18 Bilobo cup implants. Eighty-four of the 86 cases (97.7%) were considered clinically successful at the short-term follow-up (average, 30 months; maximum, 68 months) with stable fixation and reconstruction of periacetabular bone. These encouraging short-term results confirm the importance of an appropriate technique depending on the type of bone loss.
