Neurosurgical Spine Implants in Geriatric Patients Treated Surgically for Lumbar Stenosis

Abstract

Introduction. The incidence of degenerative lumbar spine stenosis increases with age. While young people tend tohave simple disc herniations with root compression, older people develop degenerative stenosis: facet joint hypertrophy,osteophytes, and ligamentum flavum hypertrophy. A typical for senility is neurogenic claudication caused by lumbarforaminal stenosis. Its symptoms decrease in spine flexion.Aim. The study consisted of a retrospective evaluation of medical data: analysis of the patient’s age, description ofthe surgical procedure and a list of spine implants.Material and Methods. The analysis included patients treated surgically for lumbar stenosis in 2020 in NeurosurgicalDepartment of Collegium Medicum in Nicolaus Copernicus University (Bydgoszcz, Poland).Results. The perioperative risk increases with the age of patients, therefore procedures in elderly patients shouldusually be less invasive, ephemeral, and even under local anesthesia. Therefore, neurosurgeons tend to insert spinalimplants in senility to support the surgical effect and optimize the time of the procedure. Interspinous spacers areimplants for neurogenic claudication. Interspinous spacers causes foraminal distraction and thus can theoreticallyinduce nerve roots decompression in indirect mechanism, less invasive, with less tissue damage. We notice significantlymore frequent use of interspinous spacers in patients over seventy.Conclusions. This observation requires further research and analysis; however, it is consistent with the availableliterature and the actual state of clinical practice. This has potentially important implications for neurosurgicalnursing — in geriatric patients after lumbar spine surgery, implants are significantly more common — interspinousspacers, which should be considered in nursing perioperative recommendations.
