{Abstract}: UNASSIGNED: Management of periprosthetic fractures has been guided by the Vancouver classification, which recommends revision for fractures around a loose femoral implant (B2). New studies have challenged this approach, demonstrating acceptable outcomes with internal fixation. This study evaluates our experience with Vancouver B2 fractures, comparing internal fixation to femoral revision. We hypothesized that in select cases with cementless stems, internal fixation would provide acceptable results with reduced morbidity.
UNASSIGNED: A retrospective review was performed of periprosthetic hip fractures treated at our institution between 1 January 2012 and 4 November 2022. We excluded patients who did not have prior radiographs and evidence of stem subsidence, suggestive of a Vancouver B2 fracture. Thirteen patients were included in the analysis.
UNASSIGNED: Four patients (31%) underwent revision of the femoral component, 4 patients (31%) underwent plating, and 5 patients (38%) underwent internal fixation with cerclage cabling. The average operative duration was 158 minutes, 203 minutes, and 62 minutes for the revision, plating, and cabling cohorts, respectively (P = .009). Blood loss was 463 cc, 510 cc, and 90 cc for the revision, plating, and cabling cohorts, respectively (P = .036). Three patients in both the revision and plating cohorts each received a transfusion (75%), whereas no patients in the cabling cohort required a transfusion (P = .033). All patients demonstrated fracture healing on the postoperative radiographs. No patients required additional surgery during the follow-up period.
UNASSIGNED: We have demonstrated that Vancouver B2 periprosthetic fractures with intact lateral cortices may be treated with internal fixation with cerclage cabling with excellent results.
