Internal decompression for spinal stenosis (IDSS) for decompression and use of interlaminar dynamic device (CoflexTM) for stabilization in the surgical management of degenerative lumbar canal stenosis with or without mild segmental instability: our initial results.

INTRODUCTION: Internal decompression of spinal stenosis (IDSS) and Posterior dynamic stabilization (PDS) form a bridge between decompression laminectomy alone and rigid fusion, by attempting to sustain beneficial effects of decompression and stabilization in an attempt to prevent bad effects of relentless degeneration.

OBJECTIVE: To evaluate the clinical outcome in operated patient of posterior dynamic stabilization.

DESIGN: Data were collected over 1 year in prospective, nonrandomized follow-up study using outcome scales.

SETTING: Single surgeon, tertiary care centre in Mumbai, India. Described here is the operative technique of posterior dynamic stabilization using CoFlex(TM) and clinical outcome of 67 consecutive patients using Visual Analogue Scale and Oswestry Disability Score.
