NCT06103396

Brief Summary

The goal of this study is to evaluate the bone regeneration capacity of BM-MSC (Bone marrow mesenchymal stromal cells), in patients with nonunion. BM-MSC cultured are seeded on a collagen scaffold, included into autologous platelet-rich plasma (PRP) clot, and implanted in the nonunion bone defect.

Outcome Measures

Primary Outcomes (2)

  • Clinical evaluation

    Time of surgical wound evolution, surgically intervened limb evolution, movility

    Baseline, 1 and 7 days. 1, 2 and 6 months. 1 and 2 years

  • Bone consolidation

    Baseline, 1 and 7 days. 1, 2 and 6 months. 1 and 2 years

Study Arms (2)

Autologuos MSCs transplantation in nonunion defects

EXPERIMENTAL

Autologuos MSCs harvested and cultured in osteogenic medium are seeded on collagen scaffold, and mixed with autologous rich plasma clot. The MSCs construct (MSCs/Col/PRP clot), is implanted in the nonunion defect.

Biological: Transplantation of autologous MSCs in nonunion fracture

Allogeneic MSCs transplantation in nonunion defects

EXPERIMENTAL

Allogeneic MSCs harvested and cultured in osteogenic medium are seeded on collagen scaffold, and mixed with autologous rich plasma clot. The MSCs construct (MSCs/Col/PRP clot), is implanted in the nonunion defect.

Biological: Transplantation of allogeneic MSCs in nonunion fracture

Interventions

At surgery, fibrotic tissue is removed from the nonunion sites. MSCs/Col/PRP clots are implanted in the site of nonunion. Patients received conventional orthopedic treatment as they needed (osteotomy, external and/or internal fixation systems, etc.)
