PAR COMPLICATIONS CONTINUED:

HARDWARE FAILURE

 CASE 6: Hardware failure. Polyethylene liner fracture.⁴ 

CASE 7: Hardware failure. Prosthetic dissociation. Note how femoral component has become disengaged from the acetabular cup.⁴

HETEROTOPIC OSSIFICATION

CASE 8: Extensive heterotopic ossification. As extensive as it is, the limb is still very functional.
