Product Overview
This convenience kit includes both the Marrow Cellution™ BMA needle for acquisition of bone marrow aspirate and an 8 gauge bone marrow biopsy needle used for percutaneous trephine extraction of autogenous bone marrow/cancellous bone dowels.
Higher quality, less quantity, delivered appropriately minimizes host morbidity.
Bone marrow aspiration and trephine extraction of cancellous bone are considered minimally invasive techniques compared to open methods of bone extraction and has been documented to have less donor site morbidity than open procedures. Additionally, bone marrow aspirate is commonly used in bone grafting procedures as it serves as a rich source of osteoprogenitor cells, and autograft bone is the "gold standard" clinical material for grafting.
Intact Bone Cores vs. Morselized Bone.
Harvesting intact cancellous bone cores without disrupting the highly-organized living tissue is superior to transplanting pieces of bone. Intact grafts maintain the micro-vascular network within the graft, promoting bone callus formation/remodeling and do not exhibit extensive resorption.
Intact bone exploits the biology of normal fracture healing rather than through slow creeping substitution associated with the slow incorporation of a non-vascularized graft.
Research demonstrates the enhanced survival of a bone graft as long as its primary blood supply is preserved. A living bone graft will shorten the time for bony onion because the reconstructed bone is comparable to a bone with a double fracture.
Allogeneic or synthetic bone chips hydrated with marrow can be packed around the living bone graft/core to accelerate anastomosis into the graft and minimize morbidity. (http://www.ranfac.com/)
