Autologous Bone Marrow Aspiration use in an Ankle Fusion

Nov 20, 2021

Bone marrow cells reside deep inside our bone cavities. In this very protected part of us, marrow cells are redundant and are throughout the bones in our bodies. The ability to use marrow as a simple aspirate, or as a concentrated sample, deliver millions of these therapeutically beneficial autologous cells.

Bone marrow aspirated from the iliac crest and other bones with reservoirs of stem cells provide an alternative to traditional Autograft harvest. Traditional aspiration retrieval methods with open-ended trocars diminish the number of key stem and progenitor cells due to the peripheral blood that enters the trocar. Additional manipulation of the traditional method of aspiration leads to volume reduction processing steps such as centrifugation outside of the sterile operating room field. Manners aspiration kit is confined to the sterile field minimizing peripheral blood infiltration with a closed stylet that pulls marrow cells from varying locations laterally through a fenestrated trocar. The current case involved a patient with end stage ankle arthritis who underwent an ankle fusion procedure. The Manners kit was used to provide bone marrow aspirate and high quality bone Autograft to the fusion site.
