Abstract:

BACKGROUND: Autologous platelet rich plasma and bone marrow mesenchymal stem cells have certain effects on bone repair, but there are rare reports on the clinical treatment of long shaft fracture bone nonunion using autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation.
OBJECTIVE: To investigate the therapeutic effect of autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation on long shaft fracture bone nonunion.
METHODS: Forty-seven patients with long shaft fracture bone nonunion were randomly divided into two groups: monotherapy group (n=22) and combination group (n=25). In the monotherapy group, autologous bone marrow mesenchymal stem cell transplantation was performed in the bone nonunion site. In the combination group, autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation was implemented in the bone nonunion site. Callus score, clinical healing time, local complications and limb function grade were recorded and compared between the two groups.
RESULTS AND CONCLUSION: The healing properties and limb function in the combination group were significantly superior to those in the monotherapy group [healing time: (4.2±1.5) vs. (5.6±1.1) months, P < 0.05; healing rate: 92% vs. 86%, P < 0.05; callus score: 2.74±0.36 vs. 2.32±0.53, P < 0.05; limb function recovery rate: 77% vs. 84%, P < 0.05]. Complications like local skin redness or infection were not found in the two groups. In conclusion, both of the two methods can promote bone healing, but autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation has a better clinical effect on bone healing.
