iMAS

iMAS represents a surgical methodology of the spine, invented by Dr. Robert L. Masson of the NeuroSpine Institute of Orlando Florida in 2003. Interpedicular Minimal Access Surgery (iMAS) describes the decompression, reconstruction and stabilization strategy associated with the use of the headless pedicle screw. Dr. Masson, using the headless pedicle screw by Synthes Spine, has developed methods which allow for 3D navigation of the spine, retraction for minimal tissue disruption, complex microsurgical decompression and interbody or onlay fusion options.

Dr. Masson, as of October 2010, has performed over 1950 lumbosacral spine reconstructions using the iMAS philosophy and methodology.
