The bone morphogenetic protein (BMP) has emerged as a suitable alternative to autogenous cancellous bone grafting and despite current knowledge about its mechanism; few studies provide evidence about the long-term safety of BMP. The aim of this investigation is to determine if BMP implantation is a safe and effective agent in a long-term setting for the treatment of patients with resistant non-unions and failed arthrodesis. This study is a retrospective case series study that was conducted on 55 patients who had received BMP. Collected data included all related surgical history, and clinical and X-ray data both pre-operatively and post-operatively. All patients were scheduled for follow-up evaluations at one week and 1, 3, 6, and 12 months post-operatively. Seven patients (13%) experienced adverse events related to their surgery with hBMP. Six patients (11%) experienced persistent non-union; five of these underwent further revision surgery. One patient (2%) developed an infected non-union. No patients experienced tumor induction, allergic reaction to hBMP. The remaining 48 patients achieved osseous union within six months of hBMP implantation. This study differs from previous studies that the use of hBMP is a safe and efficacious treatment method for resistant non-unions and failed arthrodesis in the long-term setting.
