| Popis: | Background Cement-in-cement femoral revision is a proven technique in revision total hip arthroplasty, with excellent results reported using standard-sized Exeter stems. The Exeter 44/00/125 short revision stem was introduced in 2004 to facilitate cement-in-cement revision. The stem is 25-mm shorter and has a slimmer body than standard stems to facilitate adjustment of depth of insertion and stem version. It is not known if this change in stem size affects its long-term performance. We therefore reviewed the outcome of all Exeter short revision stems used for cement-in-cement revision in our unit, with a minimum of 5 years of follow-up. Method One hundred sixty-six cases were performed between 2004 and 2010. Mean follow-up of surviving patients was 8.1 years (range 5.0-11.7). The fate of all 166 hips were known and included in the survival analysis. Results Median clinical scores improved significantly. Sixteen hips required re-revision (infection 6, loose cup 3, periprosthetic fracture 3, instability 2, stem fracture with chronic infection 1, and pain 1). Kaplan-Meier survival analysis at 10 years revealed 100% survival for aseptic stem loosening, 96.8% survival for stem failure, and 88.9% survival for all causes. Conclusion The Exeter short revision stem performed as well as standard length stems for cement-in-cement revision in this the largest and longest review of their use. Larger registry-based studies may provide additional information on the performance of this stem. |
