This study assessed the clinical and radiographical outcome of retrograde intramedullary nailing (RIN) for the treatment of periprosthetic supracondylar fractures of the femur in an elderly population.<\/jats:p> <jats:p>Between January 2014 and December 2018, 16 patients with PSF underwent RIN.<\/jats:p> <jats:p>The clinical outcome was evaluated using the Knee Society Score (KSS) and the Short-form health survey (SF-12). The radiographic outcome was evaluated directly on the X-rays. Complications were also described. 13 patients (11 females and 2 males) with a mean age of 84 years old (range, 77-89) were evaluated clinically and radiographically, after a mean of 48.3 months (range, 24-73 months). The SF-12 scores were similar to normative values for subjects in the comparable age group. Radiographic union was obtained in all patients after an average of 14,8 weeks (range, 12-40 weeks) postoperatively.<\/jats:p> <jats:p>RIN is a safe and effective treatment for PSF, above all in the elderly population.
