Cobden A, et al. - Researchers performed a retrospective study of 122 patients with the mean age of 80.6 years in order to appraise clinical and radiological outcomes of cemented calcar-replacement bipolar hemiarthroplasty (HA) for unstable intertrochanteric fractures in elderly patients. Based on Koval's categories, 21 patients (17%) exhibited 3 or 4-level decrease. Reoperation was undertaken in three patients (2 periprosthetic infections, 1 periprosthetic fracture) during follow-up. Revision of bipolar HA prosthesis was not required in any of the patients. The most common complication was femoral stem loosening and stem subsidence, which was observed in 22 patients (18%), followed by acetabular erosion that was seen in 12 patients (9.8%). The outcomes suggest the suitability of cemented calcar-replacement HA as a treatment option in elderly patients with unstable IT fractures with the benefits of satisfactory functional outcomes and lower reoperation rates.
