Objective To investigate the effect of the percutaneous autologous bone marrow stem cell transplantation for the treatment of nonunion of tibial fracture. Methods From 2007 to 2011,the data of 11 patients with tibial nonunion who received autologous bone marrow stem cell transplantation was analyzed retrospectively. Taking bone marrow,examine,isolation,cultivation and expansion marrow mesenchymal stem cells( MSCs) ,and then marrow needle was inserted into the site of the nonunion under the X-ray,the MSCs were injected into the site of nonunion.
