Percutaneous radiological autologous bone-marrow mesenchymal stem cells grafting integrating with blood plasma by injection in the part of thigh fracture: Seven-month follow-up effect evaluation in one case / 中国组织工程研究

ABSTRACT

To evaluate the clinical therapeutic effect of the autologous bone marrow mesenchymal stem cells grafting integrating blood plasma transplantation in treatment of problematic nonunion. In March 2000, a 29-year-old man presented complaints of painful walking of left thigh after a velocity injury, was selected. Radiography revealed a left femoral shaft fracture, and the bone defect distance was 5 mm through X-ray examination before operation. Following a series of reposition, fixation, intramedullary nail fixation and twice autogenous lilac bone graft treatment, external fixator and autogenous lilac bone graft treatment, totally four times, the fracture was not healed. He come to Orthopaedic Surgery Department of Siping Central Hospital to accept the autologous bone marrow mesenchymal stem cells grafting integrating blood plasma transplantation in March 2008. Under the small C-arm X-ray perspective, 4 mL bone marrow-derived mesenchymal stem cells suspension integrating 10% autologous blood plasma was injected vertically into fracture site from the skin in front of the thigh with epidural needle, and the stem cells density was 1.8 × 107 cells/L. X-ray examination was performed though out-patient recheck to observe fracture healing. Two months after graft, radiography results showed fracture interspace reduced, left femoral shaft callus was continual and fracture lines blurred partly of the left femur; furthermore, left femoral shaft fracture lines blurred, and continuous bone callus formation of the left femur at 4 months after graft; The left femur achieved bone union within 7 months. The patient was returned to full weight bearing walking and good function with a fully healed femoral bone, without any fever or infection. Percutaneous transplantation of autologous bone marrow stem cells for treatment of problematic nonunion has the satisfactory result.
