About this trial

This is an interventional treatment trial for Humerus Fracture Displaced Proximal focused on measuring large bone defect, bone marrow-derived mononuclear cells

Eligibility Criteria

50 Years - 90 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • patients aged between 50. and 90. years with proximal humerus fractures
  • indication for open reposition and internal stabilisation with a proximal fixed- angle plate for humerus (PHILOS, Synthes, Oberdorf, Swiss):
  • 2-, 3- or 4-fragment fracture according to Neer
  • dislocation of >10 mm between fragments and/or
  • angle of > 45° between fragments and/or
  • dislocation of tuberculum majus > 5 mm
  • negative pregnancy test of premenopausal women
  • signed informed consent for surgery and participation in the clinical trial

Exclusion Criteria:

  • contraindications against administration of Investigational medicinal product (IMP) is pregnancy and nursing
  • dislocation fracture
  • known psychic disorder that leads to incompliance (e.g. dementia, schizophrenia, major depression)
  • pathologic fractures caused by other underlying diseases
  • fracture-induced nerve damage
  • tumor disease with recent adjuvant therapy or treatment during the last 3 months (e.g. chemotherapy, radiotherapy), untreated tumor diseases
  • known hypersensibility against components of the transplant
  • participation in a clinical trial during the last 3 months prior to this study

Sites / Locations

  • Department of trauma-, hand- and reconstructive surgery, Goethe University, Frankfurt

Experimental

Placebo Comparator

Arm Label

BMC2012 + beta-TCP Chronos® Synthes

beta-TCP Chronos® Synthes

Arm Description

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.

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

Outcomes

Primary Outcome Measures

Secondary dislocation of fracture
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
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.
