Our scientists recently initiated a program in spine research centered on collaborations with             Drs. Kirkham Wood and Glenn Buttermann, prominent orthopaedic surgeons specializing in             spine. Project areas including vertebral fusion, spinal trauma, disc replacement and scoliosis.

Current research focuses on the use of bioresorbable polymers in spinal fusions. Unlike             metal implants, the body resorbs (breaks down and assimilates) polymeric devices after

the fusion is complete, thereby reducing complications and the need for further surgery.             A study was completed which determined the relative effectiveness of various posterior             constructs to augment anterior interbody fusions.             In an effort to improve stabilization after spinal trauma and complement a related clinical             study, a project is in progress that compares the biomechanical effectiveness of different             methods for treating thoracolumbar burst fractures.             A unique implant for disc replacement is in development and testing, and a program to             develop a novel method for treating scoliosis is also being initiated.
