Degenerative disorders of the cervical spine requiring surgical intervention have become increasingly more common over the past decade. Traditionally, open surgical approaches have been the mainstay of surgical treatment. More commonly, minimally invasive techniques are being developed with the intent to decrease surgical morbidity and iatrogenic spinal instability. ⋯ Based on the currently available literature it appears that the DTRAX® expandable cage system is an effective minimally invasive posterior cervical technique for the treatment of single-level cervical radiculopathy. Minimally invasive posterior cervical techniques continue to expand with the improvement of surgical instrumentation, microsurgical techniques and improved understanding of spinal biomechanics. While several MIS approaches already exist, there is a need for advanced and improved techniques for use in posterior cervical surgery.
