Primary Outcome Measures:
  • Absence of adverse effects during timeframe as infections or complications related with the intervention [ Time Frame: Six months ] [ Designated as safety issue: Yes ]
    The proposed trial will involve the recruitment of a total of 30 patients. The cells will be collected via bone marrow sampling. The aspirate will be centrifuged on a Ficoll density gradient to isolate mononuclear cells, wich will be resuspended in heparinized isotonic saline and used in order to infuse into the area surgically treated. The surgical intervention means the introduction of a sheet with nails according with the usually employed technique.


Secondary Outcome Measures:
  • Improvement and union of the bone [ Time Frame: One year ] [ Designated as safety issue: No ]
    The improvement of the bone nonunion will be assessed by X-ray and NMR


Estimated Enrollment: 30
Study Start Date: December 2011
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Bone marrow stem cells
Bone marrow is obtained by posterosuperior iliac crest aspiration under topical anesthesia. Mononuclear cells were isolated by Ficoll density gradient and will be resuspended in heparinized isotonic saline for mixing with osteogenic matrix.
Procedure: Osteosynthesis
To mix the cell suspension with osteogenic matrix and to use sheet and nails in order to consolidate the fracture
Other Names:
  • bone nonunion
  • bone marrow
  • mononuclear
  • fracture

Detailed Description:

In this study the investigators examine the improvement of conventional surgical treatment of long bone nonunion with the administration of bone marrow stem cells in order to achieve a higher percentage of healing and tissue reparation.
