Intervertebral disc degeneration is a significant contributor to back pain and a leading cause of disability worldwide. Numerous animal models of intervertebral disc degeneration exist. We demonstrate an ovine model of intervertebral disc degeneration, utilizing a drill bit, which achieves a consistent disc injury and reproducible level of disc degeneration.

Source: Wang, L., et.al. Full-Endoscopic Isolation Zone Technique for the Treatment of Lumbar Disc Herniation. J. Vis. Exp.(2023)This video demonstrates a minimally invasive endoscopic procedure to treat lumbar disc herniation by removing the protruded nucleus pulposus and ruptured annulus fibrosus. The technique decompresses the affected nerve root, alleviates pain, and restores nerve function through targeted tissue resection and radiofrequency modulation.

This video describes the technique of intrathecal placement of a lumbar drain in a porcine ischemic model, which helps in draining the cerebrospinal fluid to a drainage system. The cerebrospinal fluid pressure is monitored by the drainage system, and fluid is drained to maintain a constant cerebrospinal fluid pressure.

In this video, we describe the surgical procedure to induce lumbar spine instability in a mouse model by resecting the Lumbar L3 to L5 spinous process along with supraspinous and interspinous ligaments.
FAQs
Proteoglycans help the disc retain water within its extracellular matrix. As these molecules are lost, water content decreases, disc height can decline, and the disc becomes less able to distribute mechanical loads. This shift links biochemical deterioration to altered spinal mechanics and helps explain why degeneration can produce stiffness and low back pain.
Fissures in the annulus fibrosus can allow the nucleus pulposus to deform or irritate nearby tissues. This structural change may help connect disc damage with nerve-related symptoms, because altered tissue relationships can affect structures close to the disc. Recognizing this mechanism is important when clinicians interpret symptoms in the context of degeneration.
Aging and mechanical stress are recognized contributors to progressive disc deterioration, along with other risk factors. Their effects can promote loss of extracellular-matrix components, reduced water content, and impaired load distribution. Considering these influences helps explain why disc changes develop over time and why clinical assessment may need to account for more than one contributing factor.
Magnetic resonance imaging contributes to clinical assessment by helping characterize the structural condition of lumbar discs. Clinicians can consider imaging findings together with low back pain, stiffness, and nerve-related symptoms. When intervention is necessary, the resulting structural information also supports surgical planning, linking diagnostic evaluation with decisions about possible treatment.
Physical rehabilitation is one clinical approach used to address the consequences associated with lumbar disc degeneration. Its role is considered alongside clinical assessment, imaging, and pain management, with care guided by the patient’s presentation. Because degeneration may contribute to pain, stiffness, or nerve-related symptoms, rehabilitation forms part of a broader management strategy.
Surgical planning becomes relevant when treatment is considered necessary after clinical evaluation. Imaging can help describe the structural changes that clinicians must account for when planning an intervention, while symptoms provide additional clinical context. This process connects the anatomy of the degenerating disc with decisions about whether a surgical approach should be considered.
Ongoing research seeks treatments that preserve or restore disc function because degeneration can reduce water content, disc height, and the ability to distribute loads. Approaches focused on maintaining or recovering function aim to address the underlying disc changes rather than only their symptoms. This research direction complements established assessment, rehabilitation, pain management, and surgical planning.
