Abstract

Arthroplasty is an established treatment for single and multiple level cervical disc disease. Multiple contiguous arthroplasties introduce unique changes in spinal kinematics that warrant study independent of single-level surgery. The literature regarding the biomechanics, indications, outcomes and complications specific to multiple level arthroplasties was reviewed. Appropriate application of this technology has been shown to be a safe and potentially advantageous alternative to arthrodesis.
