Modular Revision System for Complex Hip Revisions: A Case Series.

ABSTRACT

Revision total hip arthroplasty (THA) is a procedure with many challenges, especially when patients exhibit femoral bone defects. The causes of these defects vary, ranging from removal of prior implants to aseptic loosening. As surgeons navigate these challenges, a reliable surgical system is important. One modular fluted tapered system provides surgeons with tools to address complex hip revision cases. Introduced in 2003, this system has been utilized in over 180,000 procedures, demonstrating its reliability and effectiveness. Previously, the body stem came in sizes 155mm to 235mm. In the discussed case series, we present six distinct patient cases that highlight the advantages and efficacy of a newly introduced modification of the system; that is the use of smaller stemmed components (now 115mm). With each patient presenting unique challenges, we have demonstrated the use of this new short-stem version for multiple applications for various revision scenarios.
