Spinal Biomechanical Modelling in the Process of Lumbar Intervertebral Disc Herniation in Middle-Aged and Elderly

Abstract

Lumbar disc herniation is one of the common clinical diseases of the lower lumbar spine in orthopedics. The purpose is to remove the herniated disc nucleus pulposus tissue, remove the compressed part of the disease, and relieve symptoms, such as nerve pain. In the past, biomechanics research mostly relied on in vitro measurements, but the complicated internal environment of the human body prevented us from further measurement and research. However, with the development of computer technology, the use of computer CT scanning, software three-dimensional reconstruction, and displacement study three-dimensional spine biomechanics method makes the research of biomechanics into in vitro simulation stage and has gradually become the focus of current research. The postoperative biomechanics was simulated and the comparison model was established at the same time. At the same time, we combined the clinical follow-up data and studied the clinical data for the treatment of postoperative recurrence of lumbar disc herniation. We compared and analyzed the initial operation method and the experimental results and obtained the prevention of recurrence. The results showed that when one inferior articular process was removed, the lumbar spine appeared unstable to rotate to the opposite side; when one inferior articular process was completely removed, the movement of the lumbar spine in all directions was unstable. Better research on the biomechanical properties of the spine will help the diagnosis and treatment of clinical lumbar disc herniation. Therefore, when performing posterior lumbar spine surgery, not only should the exposure of the surgical field and thorough decompression be considered, but also the biomechanical properties of the lumbar spine should be comprehensively evaluated.

Acupuncture treatment for lumbar disc herniation with scoliosis: A case report

“…If the nucleus pulposus protrudes in front of the nerve root, the spine bends laterally to the healthy side, which is lateral convexity to the affected side; if the nucleus pulposus protrudes in front of the nerve root, the spine bends laterally to the affected side, which is lateral convexity to the healthy side. [ 9 ] As the disease progresses and increases the rotation of the spine in the axial position, progressive subluxation of the disc in the sublateral junction area occurs, aggravating the misalignment of the posterior lumbar joints.…”

Biomechanical properties of polyvinyl alcohol hydrogel as a nucleus pulposus replacement in intervertebral disc herniation: A systematic review

“…The IVD allows flexibility and transmits physiological loads across the spine. By sending signals to cells that control appropriate matrix homeostasis, the mechanical load plays a critical role in preserving a healthy IVD (2,3). Conversely, ongoing exposure to high loading is associated with disc degeneration.…”
