Summary
A novel hook-needle intervention for lumbar disc herniation provided significant pain relief and functional improvement in a single patient. Further controlled studies are needed to confirm efficacy and safety for this minimally invasive procedure.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Procedures
- Pain Management
Background:
- Lumbar disc herniation can cause debilitating low back pain and radicular symptoms.
- A 70-year-old woman presented with chronic, aggravated low back pain and left lower limb radiculopathy.
- Imaging revealed L4/5 and L5/S1 disc herniation compressing the L5 nerve root and a sequestered nucleus pulposus.
Purpose of the Study:
- To report the clinical outcomes of a paraspinal hook-needle intervention in a patient with lumbar disc herniation.
- To evaluate the safety and effectiveness of this minimally invasive technique.
Main Methods:
- A minimally invasive paraspinal hook-needle intervention was performed under local anesthesia.
- The procedure utilized a specialized hook-shaped needle at selected lumbar segments.
- Clinical outcomes were assessed through physical examination, range of motion, muscle strength, sensory testing, and validated pain/disability scores.
Main Results:
- The patient experienced marked relief from low back pain and radicular symptoms.
- Significant improvements were observed in lumbar range of motion, paraspinal muscle tension, and tenderness.
- Motor strength, sensory deficits, and functional status (Visual Analog Scale, Oswestry Disability Index) showed substantial improvement.
- Radiographic evidence of sequestered nucleus pulposus disappearance was noted post-intervention.
- No adverse events were reported during the 1-year follow-up.
Conclusions:
- The paraspinal hook-needle intervention was associated with significant clinical improvement in this case of lumbar disc herniation.
- The observed radiographic resolution of sequestered nucleus pulposus warrants further investigation.
- While promising, the temporal association does not confirm causality; prospective controlled studies are essential to establish efficacy and safety.

Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
