Percutaneous Stenoscopic Lumbar Decompression with Paramedian Approach for Foraminal/Extraforaminal Lesions

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Minimally Invasive Spine Procedures

Background:

• Degenerative diseases commonly affect the lumbar foramen, leading to conditions like extraforaminal disc herniation and foraminal stenosis.
• These conditions can cause significant pain and neurological deficits, necessitating effective treatment strategies.

Purpose of the Study:

• To describe the technique of percutaneous stenoscopic lumbar decompression with a paramedian approach (para-PSLD).
• To evaluate para-PSLD for treating foraminal and extraforaminal lumbar lesions.

Main Methods:

• Procedures were performed using a uniportal endoscopic instrument system.
• The paramedian approach (para-PSLD) was utilized for accessing foraminal and extraforaminal areas.

Main Results:

• The para-PSLD technique is applicable to patients with foraminal stenosis, narrow disc space, or facet joint hypertrophy.
• This approach provides anatomical visualization comparable to open surgery, ensuring good visualization of target areas.

Conclusions:

• Percutaneous stenoscopic lumbar decompression with a paramedian approach (para-PSLD) is a viable alternative.
• It represents a minimally invasive option for managing degenerative lumbar foraminal and extraforaminal stenoses.
