RESUMO
<p><b>OBJECTIVE</b>To evaluate the effect of cemented long stem bipolar prosthetic prosthesis in the management of unstable intertrochanteric fractures in the elderly.</p><p><b>METHODS</b>A retrospective analysis of 23 elderly cases of uncemented long-stem prosthetic replacement for unstable intertrochanteric fractures was conducted. Of the 23 elderly patients, 6 had type IIA fracture by Evans-Jenson classification, 11 had type IIB fractures, and 6 had type III fractures.</p><p><b>RESULTS</b>One patient died due to severe respiratory failure during the follow-up period. The patients were followed up for 6 to 10 months (mean 15 months), and no dislocation, infection, loosening or sinking of the prosthesis was found in the followed-up cases with a Harris score reaching 84.8.</p><p><b>CONCLUSION</b>Cemented long-stem bipolar prosthetic prosthesis replacement is effective for management of unstable intertrochanteric fractures in the elderly.</p>
