Abstract:

BACKGROUND: Bone nonunion is a common complication in the orthopedic treatment, and its morbidity reached 5%-10%, which results in the long-term functional disturbance of the limbs, and even disability. Autogenous iliac crest graft has been commonly used to treat bone nonunion, but some limitations still exist.
OBJECTIVE: To investigate the treatment outcomes of autogenous iliac crest graft combined with autologous bone marrow stem cell transplantation for bone nonunion after fracture surgery.
METHODS: Clinical and follow-up data from 69 patients with bone nonunion were analyzed retrospectively. All patients were allotted to combination (n=37) and iliac (n=32) groups, followed by treated with autologous iliac crest graft combined with autologous bone marrow stem cell transplantation or  autologous crest graft, respectively. Afterwards, the hospitalization time, fracture healing time, bone mineral density and Fereadez-Esteve callus scores were detected and compared between groups.
RESULTS AND CONCLUSION: The hospitalization time did not differ significantly between groups
(P > 0.05). The fracture healing time in the combination group was significantly shortened compared with the iliac group (P < 0.05). The bone mineral density and Fereadez-Esteve callus scores in the combination group were significantly higher than those in the iliac group at 3 and 6 months after surgery (P < 0.05). The excellent and good rate of the affected limb function in the combination group was significantly higher than that in the iliac group (P < 0.05). These results suggest that autogenous iliac crest graft combined with autologous bone marrow stem cell transplantation for bone nonunion can accelerate fracture healing, promote porosis and improve the functional recovery of affected limbs.
