Minimally Invasive Device for Harvesting Iliac Crest Bone Graft

Johns Hopkins University, 2010 - $20,000

There are over 1.5 million spinal fusion surgeries performed annually worldwide. Bone grafting is the standard practice in orthopedic medicine to foster restoration and healing of the spine in addition to providing structural and biological support. The current gold standard for graft materials is the autologous bone graft, which uses cancellous bone from the patient’s own hip (clinically termed the iliac crest bone graft or ICBG). ICBG produces the best results, but it must be extracted through an invasive procedure that is cumbersome for the surgeon and painful for the patient. There is currently no specialized device designed to extract sufficient volumes of ICBG for spinal surgery without high risk to the patient.

This team’s goal is to dramatically improve the procedure for extracting ICBG. The device will be minimally invasive, will standardize the harvesting procedure, and will allow for safe extraction of large volumes of ICBG. This will increase spinal fusion success rates while reducing patient morbidity, surgical time, and healthcare expenditures.
