Abstract:
PURPOSE:Lumbar spinal canal stenosis and lumbar spinal foraminal stenosis are common, degenerative pathologies which can result in neurogenic claudication and have a negative impact on function and quality of life. Percutaneous interspinous devices (PIDs) are a recently-developed, minimally-invasive, alternative treatment option. This study details a 9 year single-centre experience with PIDs and examines the complementary use of spinous process augmentation (spinoplasty) to reduce failure rates. METHODS:A retrospective cohort assessment of 800 consecutive patients who presented to a specialized spine hospital was performed with 688 receiving treatment. Inclusion was based on high-grade stenosis, failure of conservative management and electromyography. 256 had a PID alone while 432 had concurrent polymethyl methacrylate (PMMA) augmentation of the adjacent spinous processes. The patients were followed up at 3 and 12 months using the Zurich Claudication Questionnaire (ZCQ) and Oswestry Disability Index (ODI). RESULTS:Both groups showed marked improvement in the patients' ZCQ scores (3.2 to 1.3) and ODI scores (32 to 21), with strong satisfaction results (1.7). The symptom recurrence rate from complications for the group which received concurrent spinous process augmentation was reduced when compared with the PID alone cohort (<1% vs 11.3%). CONCLUSION:This study demonstrates the efficacy of percutaneous interspinous devices in treating lumbar spinal stenosis. It also provides evidence that concurrent spinous process augmentation reduces the rate of symptom recurrence.
