Controversies about Interspinous Process Devices in the Treatment of Degenerative Lumbar Spine Diseases: Past, Present, and Future
نویسندگان
چکیده
A large number of interspinous process devices (IPD) have been recently introduced to the lumbar spine market as an alternative to conventional decompressive surgery in managing symptomatic lumbar spinal pathology, especially in the older population. Despite the fact that they are composed of a wide range of different materials including titanium, polyetheretherketone, and elastomeric compounds, the aim of these devices is to unload spine, restoring foraminal height, and stabilize the spine by distracting the spinous processes. Although the initial reports represented the IPD as a safe, effective, and minimally invasive surgical alternative for relief of neurological symptoms in patients with low back degenerative diseases, recent studies have demonstrated less impressive clinical results and higher rate of failure than initially reported. The purpose of this paper is to provide a comprehensive overview on interspinous implants, their mechanisms of action, safety, cost, and effectiveness in the treatment of lumbar stenosis and degenerative disc diseases.

متن کاملTreatment of 44 Cases With Lumbar Spine Stenosis and Degenerative Instability: Outcomes of Surgical Intervention
Background and Aim: Degenerative lumbar spine disease can lead to lumbar spine instability. The patients can present with Low Back Pain (LBP), radicular pain, and motor and sensory dysfunction. Age >50, female sex and pregnancies are among prevalent risk factors. The degeneration process usually starts from the intervertebral discs progressing to involve facet joints, ligaments, and vertebral b...
متن کاملA Short History of Posterior Dynamic Stabilization
Interspinous spacers were developed to treat local deformities such as degenerative spondylolisthesis. To treat patients with chronic instability, posterior pedicle fixation and rod-based dynamic stabilization systems were developed as alternatives to fusion surgeries. Dynamic stabilization is the future of spinal surgery, and in the near future, we will be able to see the development of new de...
