title: Extensively coated cementless femoral components in revision total hip arthoplasty: an update.
abstract: The vast majority of femoral revisions that an orthopaedic surgeon encounters can be treated successfully with an extensively porous coated stem. Long-term results have demonstrated that this type of implant can provide reliable initial fixation with a high propensity for long-term fixation. Depending on the degree of femoral bone loss (Paprosky Type IIIA or Type IIIB bone), a longer cementless stem may be required to obtain initial axial and rotational stability. If severe bone loss is present (Paprosky Type IV bone), large canal diameters are encountered (>19 mm), or if torsion remodeling of the proximal femur has occurred, alternative methods of fixation may be required.
