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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: BMC2012 + beta-TCP Chronos® Synthes

The large bone defect will be bridged as per clinical standard, filled with a clinically established scaffold (beta-TCP Chronos® Synthes), and loaded with 1.3 x 10E6 BMC/ml TCP per 1 ml beta-TCP in situ.

Biological: BMC2012

Placebo Comparator: beta-TCP Chronos® Synthes

The large bone defect will be bridged as per clinical Standard and filled with a clinically established scaffold (beta-TCP Chronos® Synthes).

Device: beta-TCP Chronos® Synthes

Outcome Measures

Primary Outcome Measures

  1. 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

  1. 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.

Other Outcome Measures

  1. Concomitant medication [day -1]

    Documentation of concomitant medication

  2. Adverse events [day -1]

    Documentation of adverse events

  3. Concomitant medication [day 0]

    Documentation of concomitant medication

  4. Adverse events [day 0]

    Documentation of adverse events

  5. Concomitant medication [week 1]

    Documentation of concomitant medication

  6. Adverse events [week 1]

    Documentation of adverse events

  7. Concomitant medication [week 6]

    Documentation of concomitant medication

  8. Adverse events [week 6]

    Documentation of adverse events

  9. Concomitant medication [week 12]

    Documentation of concomitant medication

  10. Adverse events [week 12]

    Documentation of adverse events

  11. Degree of bony bridging (percent of defect area) in the bone fracture [week 1]

    Analysis of fracture healing by radiologic evaluation, consolidation, necrosis

  12. Degree of bony bridging (percent of defect area) in the bone fracture [week 6]

    Analysis of fracture healing by radiologic evaluation, consolidation, necrosis

  13. Degree of bony bridging (percent of defect area) in the bone fracture [week 12]

    Analysis of fracture healing by radiologic evaluation, consolidation, necrosis
