- Minimally invasive endoscopic methods, performed by passing the scope from the skin surface, should be differentiated from open surgery.
- These are "dot" opening procedures, (with skin openings just large enough to admit the scope), for internal viewing through scope placement directly at the tissue, to be addressed (with no cutting muscle or removal of bone or ligament in gaining access) as compared to working from an external view,(either with or without a microscope), through an open incision (cutting muscle, removing ligament, bone and joint capsule; pulling and holding over nerves for an extended period, in obtaining access to the disc).
- Why is non-traumatic discectomy so safe?
- Small Size (2.8.mm)
- Precise Control
- Visualization while working
- No access Damage
- Local Anesthesia
- Builds upon the safest proven approach(APLD)
- INDICATIONS
- Radiculopathy caused by disc compromise(Contained or non-contanined) accessible to percutaneous intruments
- Pain that has not responded to conservative treatments
- Herniated , prolapsed, bulging, or extruded discs confirmed by CT, MRI, Myelogram or Discogram
- Indications are evolving due to rapid changes in percutaneous instruments
- Radiating pain, numbness, weakness (not responding to conservative treatment)
- CONTRA-INDICATIONS
- Lateral lumbar spinal canal stenosis caused by bone
- Bony spurs, facet hypertrophy, ligamentous hypertrophy causing neural encroachment
- Spinal Instability
- Inaccessible free fragments
- Distal major joint pathology
- Significant cicatrix or arachnoiditis
- TECHNIQUE
- Posterior-Lateral approach
- Symptomatic Side up
- Lateral Position (Safer for avoiding abnominal structures)
- Puncture Opening
- Inject Local
- Maek approx. 5mm skin opening(to be closed with a steri-strip and bandaid)
- No stitches
- EXTRUDED DISC
- Grasper can remove a 2cm disc fragment through the working channel scope
- ALPD : Long-Term Follow-up
- "This procedure was the lowest morbidity of all invasive treatment options in the care of patients with herniated lumbar discs" [Gill & Blumenthal, Actaorthop scand]
