Summary
A new device improves percutaneous endoscopic lumbar discectomy (PELD) for lumbar disc herniation (LDH). This tool enhances disc positioning accuracy, potentially reducing radiation exposure and surgeon training time.
Area of Science:
- Neurosurgery
- Medical Devices
- Spinal Surgery
Background:
- Lumbar disc herniation (LDH) causes radicular pain due to nerve root compression.
- Surgical options for LDH include conventional and minimally invasive discectomy.
- Percutaneous endoscopic lumbar discectomy (PELD) offers benefits but faces challenges in disc positioning and radiation exposure.
Purpose of the Study:
- To develop and evaluate a novel positioning device for PELD.
- To improve the precision and efficiency of disc localization during PELD procedures.
- To reduce reliance on fluoroscopy and associated radiation exposure.
Main Methods:
- Developed a percutaneous endoscopic lumbar disc positioning device using 3D modeling and computer-aided design.
- Fabricated a base plate and designed guiding components for spinal positioning.
- Conducted accuracy testing on porcine spines to assess device performance.
Main Results:
- The device accurately located target positions on porcine spines.
- Demonstrated potential to reduce fluoroscopic dependence in experimental settings.
- The device offers high precision, supports minimally invasive approaches, and provides multi-directional instrument guidance.
Conclusions:
- The novel positioning device offers a structured and reproducible method for PELD.
- It has the potential to enhance procedural efficiency and limit radiation exposure.
- This tool may significantly aid surgical training for early-career spine surgeons.
