Research Abstract

The Use of Radiostereometric Analysis (RSA) in Spinal Surgery

RSA is a technique that quantifies how bones (and/or an implant) move with respect to each other using biplanar radiography. RSA has the potential to answer many clinical questions with regards to spinal surgery. Our current efforts have focused on clinical studies using RSA to evaluate fusion, discectomy, intervertebral disc replacement and dynamic stabilization.

Pedicle Screw Fixation in Osteoporotic Bone

Pedicle screw fixation in osteoporotic bone is problematic. Failure of fixation at the screw-bone interface can lead to mechanical and neurological complications. This is especially true in patients with osteoporosis who require pedicle screw fixation for progressive fracture deformity or neurological deterioration. We have been investigating pedicle screw features and techniques in order to optimize the fixation strength of the screw-bone interface.

Biomechanical Assessment of Nucleus Replacement

Degeneration and herniation of the intervertebral disc can result in the stimulation of mechanical and/or chemical pain generators. Replacement of the intervertebral disc has been attempted in the past, however replacement of the entire disc may not be necessary in a number of clinical situations. We have been investigating novel new approaches and technologies that focus on replacement of only the nucleus and sustaining the integrity of the annulus.
