Each year, approximately 6 million fractures occur in the United States which requires a total of 9 million physician visits and causes a loss of more than 36 million work days (American Academy of Orthopaedic Surgeon). One particular challenging condition that fracture can leave with the patient is segmental defects. Large segmental defects are often hard to manage and require multi-phase surgery to restore sufficient function and union. Current treatment options include autografts, allografts, and distraction osteogenesis. Though these treatments have brought forth clinical successes, they are still with considerable limitations. To overcome the limitations in these treatment options, researchers are exploring for new treatment methodologies. In our laboratory, we are investigating the use of rapid prototyping technique for manufacturing biodegradable, load-bearing bone tissue engineering scaffolds, and the in vivo evaluation of such scaffolds.
