Feasibility Study of Aastrom Tissue Repair Cells to Treat Non-Union Fractures.

Stopped early · Phase 1/Phase 2

Conditions studied: Fracture, Ununited, Pseudarthrosis

In brief

The purpose of this multi-center study is to obtain clinical data to substantiate that Aastrom TRC autologous bone marrow cells will regenerate bone in patients with established (appendicular skeletal) non union fractures, when used with one of the commonly employed commercially available allograft chip matrices.

• The use or discontinuance of ethanol and/or cigarettes/cigars will be noted in the patient's case report forms.
• Patients who require corticosteroid anti-inflammatory therapy after surgery.
