BACKGROUND: Revision surgery is currently the recommended treatment for Vancouver B2 femoral periprosthetic fractures, but isolated open reduction and internal fixation (ORIF) might be an effective treatment for these fractures around cemented collarless polished tapered (CCPT) stems, as these stems can re-engage in the cement mantle, regaining stability following internal fixation. The aim of this study was to determine the operative risks, post-operative complications, and radiographic and functional outcomes in two cohorts of Vancouver B2 femoral fractures around CCPT stems treated either by ORIF alone or revision surgery. METHODS: The results of 12 patients with B2 periprosthetic fractures around a CCPT stems treated by ORIF alone (median follow-up 67 months) were compared with those of nine patients with a similar fracture treated by revision surgery (median follow-up 59 months). RESULTS: All fractures treated by ORIF alone healed and all stems restabilized and remained stable within their original cement mantle. These patients had significantly shorter overall operating room times (P = 0.002), surgical times (P = 0.002) and required fewer units of blood transfusion (P = 0.008) than patients in the revision cohort. In the ORIF cohort, one patient had two dislocations. In the revision cohort, one patient had delayed wound healing, a second patient had delayed wound healing and two dislocations, and a third patient had two dislocations. CONCLUSION: Although further studies with larger numbers are required, treatment of these fractures with ORIF alone may be a viable alternative to revision surgery as it reduces the operative risks involved.
