This convenience kit includes an 8 gauge bone marrow biopsy needle used for percutaneous trephine extraction of autogenous bone marrow/cancellous bone dowels. Trephine extraction of cancellous bone is considered minimally invasive technique compared to open methods of bone extraction and has been documented to have less donor site morbidity than open procedures.(1,2,3). Autograft bone is consider as the “gold standard” clinical material for grafting. (4,5) 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. (6,7)
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. (6) 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 union because the reconstructed bone is comparable to a bone with a double fracture. (6,7)
- Graft material with osteoconductive, osteoinductive & osteogenic properties.
- Minimally invasive technique – using a 8 Gauge Trephine Needle for bone core extraction.
- Graft material may be combined with autologous, allogenic, xenogenic or synthetic bone chips hydrated with high cellular marrow aspirate.
- Reduces donor site morbidity associated with standard harvesting techniques.
