Summary
Transforaminal endoscopic lumbar discectomy (TELD) effectively treats lumbar disc herniation with bilateral symptoms using a unilateral approach. This minimally invasive technique significantly reduces leg pain and improves function, offering a high success rate.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
- Spinal Endoscopy
Background:
- Transforaminal endoscopic lumbar discectomy (TELD) is a minimally invasive spinal surgery.
- Unilateral TELD for disc herniation causing bilateral symptoms presents a surgical challenge.
- This study introduces a percutaneous endoscopic herniotomy technique using a unilateral approach for lumbar disc herniation with bilateral symptoms.
Purpose of the Study:
- To describe and evaluate a unilateral percutaneous endoscopic herniotomy technique for lumbar disc herniation with bilateral symptoms.
- To assess the efficacy of this minimally invasive approach in alleviating bilateral leg pain and improving functional status.
Main Methods:
- Twenty-six patients with lumbar disc herniation causing bilateral leg pain/weakness underwent unilateral TELD.
- Clinical outcomes were assessed using the Visual Analogue Scale (VAS) for pain and Oswestry Disability Index (ODI) for function.
- Follow-up evaluations occurred postoperatively, at 3 months, and 12 months, with surgical satisfaction assessed at final follow-up.
Main Results:
- Significant improvement in VAS leg pain scores on both operative (8.39 to 2.18) and contralateral sides (7.12 to 1.57) was observed postoperatively.
- Oswestry Disability Index scores improved from a mean of 83.63 preoperatively to 17.54 at 12 months postoperatively.
- A high success rate was achieved, with 96.2% of patients reporting good or excellent global results.
Conclusions:
- Unilateral TELD is an effective surgical option for treating lumbar disc herniation that causes bilateral symptoms.
- This minimally invasive technique, performed through a single working channel, provides significant pain relief and functional recovery.
- The study supports the use of TELD as a viable alternative to open discectomy for selected cases.

01:29Herniated 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...
01:23Degenerative 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...
