Mechanical failure in the femoral component in total hip replacement.
Bone-cement lucency and migration into varus position, expressed as failure modes lb and IV, appear to be unfavorable. The majority of prostheses carry a collar that rests on cement, and in such implant types, migration of up to 4 mm within the cement mantle does not appear to be associated with an increased risk of revision.
