Max More Spine - Percutaneous Stenoscopic Lumbar Decompression (PSLD) Endoscopic System
Lumbar spinal decompression is performed with a posterior interlaminar approach. A skin incision of app. 8-9mm is made in the interlaminar window. A conical blunt dilator is introduced in the interlaminar window. A working cannula is introduced over the dilator with the beveled opening of the working cannula directed medially towards the ligamentum flavum. Sequential trimming of the Inferior articular process- Superior Lamina, Superior articular process – Inferior lamina is performed with motorised drills & Kerrison rongeurs.
- Interlaminar Lumbar stenosis Decompression
- Central & B/L Lateral Recess
- Lumbar disc herniation – Interlaminar approach
- Cervical procedure posterior approach
- Developed in cooperation with Dr Kangtaek Lim and Dr Gun Choi
After completion of bony decompression, Ligamentum flavum is removed ipsilaterally and centrally within the bony window created by trimming the facet & lamina, Complete decompression of the thecae sac & ipsilateral traversing root is performed from tip if the Superior articular process to 1/2 of caudal pedicle. For contralateral decompression the base of the spinous process is trimmed with the motorised drill and contralateral bony & soft tissue decompression performed with thinning of the lamina, Trimming the Inferior articular process, Superior articular process, cranial & Caudal lamina dorsal to the thecal sac. Ligamentum flavum is removed to decompress the contralateral traversing root. The entire procedure is performed under endoscopic visual control using the MaxMoreSpine 5.7 mm endoscope.
