Dynamic stabilization (dynesys) is an excellent alternative to rigid fusiion surgery.

Danek Satellite, Fernstrom Ball


This animation demonstrates the biomechanics of the Fernstrom ball or Satellite sphere as a disc nucleus replacement (officially an interbody arthrodesis device). After a large disc herniation is removed, the cobalt chrome (Vitallium) sphere is inserted into the disc interspace restoring height lost as a result of the disc herniation.... Unlike total disc replacements such as the Depuy Charite, the Satellite sphere is placed via a minimally invasive laminectomy (posterior) approach and with only minimal pain.

Gamma Knife Central


Day after Memorial day in the "bunker" under Kettering Medical Center (Dayton Ohio).... It is good to get back into the Gamma Knife routine.... I am one of only five surgeons in the country doing this procedure. This procedure is a "motion sparing" type of lumbar fusion. That sounds like a bit of an oxymoron, except that this is how the device is classified by the FDA. The idea is to replace a removed nucleus pulposis (disc herniation) with a cobalt chrome sphere that restores the normal disc motion and preserves disc height. The original device, the Harmon sphere, made of vitallium, resulted in interbody fusions in some cases, hence the classification as a fusion device.
