Tantalum in type IV and V Paprosky periprosthetic acetabular fractures surgery in Paprosky type IV and V periprosthetic acetabular fractures surgery.

Periprosthetic fractures of the acetabulum with bone loss are a rare but potentially disastrous complication of total hip prostheses. Their management and therapeutic choice will test the ability of the orthopedic surgeon. It is important to determine the type of fracture and characteristics in order to pursue an adequate therapeutic strategy. The modern biomaterials, such as porous tantalum, offer a greater potential in replacing bone loss, promoting bone regrowth and obtaining a stable implant.
