The radiological outcome of lumbar spinal fusion using a South African-developed dynamic spinal fixation system.

Objectives: To investigate the radiological outcome of the use of a new Cape Town-developed spinal fixation system.

Design: One hundred and fifty-five patients underwent posterior lumbar spinal fusions with this fixation system and autogenous bone graft more than a year ago. Of these 121 were available for radiological follow-up.
