The Efficacy of Mesenchymal Stem Cells for Stimulate the Union in Treatment of Non-united Tibial and Femoral Fractures in Shahid Kamyab Hospital

Study Overview
=================
Brief Summary
-----------------
Because the rate of non union of long bone in lower extremities specially in tibia in this two last decade due to malnutrition and smoking and other risk factors was increased, so many patient in our country suffer from non union on the other hand it seems that the use of the mesenchymal stem cells can irritate the union rate. Therefore the investigators decide to inject the mesenchymal stem cell derived from iliac bone marrow after centrifuge with ficoll procedure to non union site in patient that are resistant to other treatment. Then the investigators will follow the patient with monthly radiography and evaluate the callus volume and clinical union and any side effect of this treatment.clinical union consider to relief pain in non union site and be stable in examination.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: mesenchymal stem cell<br>stem cells drived from iliac bone marrow with centrifuge and ficoll method then inject to non union site 2-3 ml with approximately 40 X 10E6 Mesenchymal Stem Cells (MSC) will be injected in the nonunion site of the bone fracture under fluoroscopic gide and general or spinal anesthesia as deemed appropriate by the anesthetist. | Other: injection the mesenchymal stem cell in non union site<br> <br> |
