From: An in vivo study to investigate an original intramedullary bone graft harvesting technology
Reduction of femoral cortical bone volume after BG harvesting based on a comparison of preoperative and postoperative CT scans. Reaming volume was determined to be between + 20% and − 20% from the middle of the bone A. Representative images of cylinder volume, i.e., volume difference due to reaming, indicated by dashed lines, measured as increase in intramedullary volume in pre- and postoperative comparison B. Similar to slightly higher bone volume reduction for the RIA 2 compared to the ARA group C. Means ± SD, n = 8
