Orthopaedic crossfire--Stem modularity is unnecessary in revision total hip arthroplasty: in opposition.

Abstract

If distal fixation is a goal in revision hip surgery, then modularity may not be necessary. If, however, proximal fixation is desired, both proximal and distal fit and fill are necessary to achieve initial stability. This can only be done in the revision situation by using a modular stem. Long-term follow up of 320 revision cases treated using a proximally modular proximal ingrowth stem shows a re-revision rate for late aseptic loosening of 0.93% at a mean time of 7 years, indicating that such a stem is a reasonable option.
