230 · DOS Abstracts Periprosthetic Hip Infection treated with Two- Stage Stage-One Select Spacer – Complication rate and restoration of anatomy Josephine Olsen Kipp, Stig Storgaard Jakobsen, Martin Lamm, Kjeld Søballe Department of Orthopaedic Surgery , Aarhus University Hospital Background: Two-stage revision is used as treatment of periprosthetic hip joint infection (PHJI). ‘StageOneTM Select Hip Cement Spacer’ prevents con- tractures, preserves bonestock with the ability to adjust leg length and offset. Purpose / Aim of Study: The aim of this study is to evaluate complications, bone destruction, mobilization and restoration of natural joint anatomy with the StageOne Select Spacer. Materials and Methods: From 2013-2017 twenty-one patients had PHJI and received a StageOne Select Spacer. Through review of medical records we obtained the pre- per- and postoperative data and serial x-ray was evaluated. Findings / Results: One (4.8%) dislocated the spacer hip, one (4.8%) sus- tained a periprosthetic fracture, two (9.5%) got reinfected and one (4.8%) nev- er succeeded to get control of the infection. Two (9.5%) died unrelated to the spacer implantation. Pre- vs. postoperative leg length was 1.5 mm (-4,8-6.3) and offset was 0.5 mm (-2.3-5.5). Conclusions: The StageOne Select Spacer shows promising results in treat- ment of PHJI. Complication rate was equal or lower than other studies and the spacer will restore the natural anatomy of joint, especially on the femoral side. 171.
