BMC2012: Cell Therapy by Autologous BMC for Large Bone Defect Repair
Study Details
Study Description
Brief Summary
In the present phase-II clinical trial the researchers investigate efficacy and proof of concept of the augmentation with preoperatively isolated autologous BMC cells seeded onto ß-TCP in combination with an angle stable fixation (Philos plate®) for the therapy of proximal humeral fractures.

Outcome Measures
Primary Outcome Measures
- Secondary dislocation of fracture [12 weeks]
Secondary dislocation is diagnosed on plain radiographs, if more than 20° varus collapse of the humeral head fragment in relation to the humeral shaft and / or screw penetration through the humeral head is detected
Secondary Outcome Measures
- Functional outcome after fixation [12 weeks]
Functional outcome after fixation will be recorded by the Dash-Score at week 12; assessment of safety: all adverse reactions will be recorded and analyzed.
