Analysis of curative effect of percutaneous autologous bone marrow cell transplantation for treating nonunion under laser positioning and navigation guidance

Abstract

Fracture end cleaning, local bone grafting, and fixation are the classic treatment methods for fracture nonunion, but patients normally need to wait for a long time to ensure that there are signs of further healing. The purpose of this research is to verify whether precision injection improvement can be developed as treatment associated with autologous bone marrow cell injection to promoting fracture healing. The curative effect of traditional autologous bone marrow injection for the treatment of poor fracture healing is affected by injection accuracy and locally available cell retention the clinical. The curative effect of autologous bone marrow injection can be effectively improved through autologous bone marrow centrifugation and bone grinding at fracture end when combined with preoperative three-dimensional computed tomography (CT) planning. This minimally invasive treatment method is especially suitable for patients with delayed fracture healing within six months of presentation. Patients with nonunion over six months can be treated with improved autologous bone marrow injection. The convenient and minimally invasive method itself will not be difficult for patients, physically and mentally, and the most reliable treatment method for nonunion is to cut and clean hardened bone and implant autologous bone fixation.
