Background: Currently, the available treatments for long bone nonunion (LBN) are removing of focus of infection, bone marrow transplantation as well as Ilizarov methods etc. Due to a high percentage of failures, the treatments are complex and debated.To develop an effective method for the treatment of LBN, we explored the use of human autologous bone mesenchymal stems cells (hBMSCs) along with extracorporeal shock wave therapy (ESWT). Materials and Methods: Sixty three patients of LBN were subjected to ESWT treatment and were divided into hBMSCs transplantation group (Group A, 32 cases) and simple ESWT treatment group (Group B, 31 cases). Results: The patients were evaluated for 12 months after treatment. In Group A, 14 patients were healed and 13 showed an improvement, with fracture healing rate 84.4%. In Group B, eight patients were healed and 13 showed an improvement, with fracture healing rate 67.7%. The healing rates of the two groups exhibited a significant difference (P < 0.05). There was no significant difference for the callus formation after 3 months treatment (P > 0.05). However, the callus formation in Group A was significantly higher than that in the Group B after treatment for 6, 9, and 12 months (P < 0.05). Conclusion: Autologous bone mesenchymal stems cell transplantation with ESWT can effectively promote the healing of long bone nonunions.
