Dynamic Stabilization for Challenging Lumbar Degenerative Diseases of the Spine : A Review of the Literature

Abstract EN

Fusion and rigid instrumentation have been currently the mainstay for the surgical treatment of degenerative diseases of the spine over the last 4 decades.

In all over the world the common experience was formed about fusion surgery.

Satisfactory results of lumbar spinal fusion appeared completely incompatible and unfavorable within years.

Rigid spinal implants along with fusion cause increased stresses of the adjacent segments and have some important disadvantages such as donor site morbidity including pain, wound problems, infections because of longer operating time, pseudarthrosis, and fatigue failure of implants.

Alternative spinal implants were developed with time on unsatisfactory outcomes of rigid internal fixation along with fusion.

Motion preservation devices which include both anterior and posterior dynamic stabilization are designed and used especially in the last two decades.

This paper evaluates the dynamic stabilization of the lumbar spine and talks about chronologically some novel dynamic stabilization devices and thier efficacies.
