Cement-in-cement versus uncemented modular stem revision for Vancouver B2 periprosthetic fractures.

Background To compare outcomes of revision to a long uncemented stem with cement-in-cement revision for Vancouver B2 periprosthetic fracture (PPF). Methods Patients undergoing surgery for a Vancouver B2 PPF in a cemented stem from 2008 to 2018 were identified using our prospectively collated database. Results We identified 43 uncemented and 29 cement-in-cement revisions. Cement-in-cement revision had a shorter operative time, reduction in certain complications, no increased rate of non-union, lower degree of stem subsidence and no difference in re-revision rate. Conclusion With appropriate patient selection, both cement-in-cement and long uncemented stem revision represent appropriate treatment options for Vancouver B2 fractures. [ABSTRACT FROM AUTHOR]
