Grafting of Expanded Mesenchymal Stem Cells without Associated Procedure in a Healed Case of Ulna Pseudarthrosis: A Case Report.

BACKGROUND

The surgical management of pseudoarthrosis is often a challenge. The use of mesenchymal multipotent cells expanded and manipulated in the laboratory is an interesting treatment of pseudoarthrosis, because they can lead to differentiation into osteocytes and thus the formation of bone tissue.

CASE DESCRIPTION: We present a case of a 47-years-old man with isolate ulna fracture, treated with plate and screws and evolved in non-union. The patient underwent an expanded stem cells graft on the site of non-union with a small incision of approximately 3cm, without changing the synthesis system. After one year, the X-ray showed a complete fracture consolidation.

DISCUSSION: In our opinion, this case is interesting because it highlights the cellular action that is the only healing factor; it is an important demonstration of the biological action of expanded mesenchymal stem cells (MSCs).

CONCLUSION

To validate the use of MSCs, it is necessary to perform comparative studies for age, sex, general condition, location, and mechanism of injury as a further clinical validation of the efficiency of this cell line.
