Introduction
The lumbar spine are the lower 5 vertebrae (L1-L5). The lowest vertebra of the lumbar spine, L5, connects to the top of the sacrum. Some people have an extra, or sixth, lumbar vertebra which is considered a normal variant.
The problem of prolapsed lumbar intervertebral disc is common because of the fact that the lumbar region is the highest stress-bearing area of the spinal column. Prolapsed lumbar discs may cause altered nerve sensation and nerve root pain ‹sciatica›.
Stenotic lumbar canals are another entity where there is no disc prolapse but the lumbar canal or its foramens are extremely tight causing pressure on the nerves and pain and may lead to a particular type of pain known as neurogenic claudication.
Endoscopic surgery of the lower back
Surgical options are usually considered for more rapid relief or with failure of non-surgical treatment such as medications and physiotherapy. To remove a disc prolapse or decompress lumbar canal and nerve roots, surgeons have traditionally relied on the open technique known as laminectomy and discectomy. This involves a large incision and extensive dissection with excessive bone and ligament removal.
Endoscopic lumbar surgery is performed through a small «stab» skin incison in the lower back. An endoscope is inserted at the targeted level. Using specialized miniature endoscopic instruments, only a portion of the prolapsed lumbar disc that presses the nerve, or nerves, is resected or a stenotic area is decompressed. Muscles and ligamentous structures are conserved; therefore, there is much less discomfort after the procedure. Hospital stay is overnight.
Benefits
- Preservation of intervertebral joints, ligaments, muscles, and other softmtissue structures = strong back
- A truly minimally invasive procedure = no unnecessary injury to body tissue
- Direct access to herniated disc = precise surgery
- Small incision = minimal scarring, reduced risk of infection, minimized blood loss
- Markedly less postoperative pain = minimal patient distress = fully ambulatory after surgery = speedy recovery, discharge home on second day of surgery
- No limitation of movements, restrictions or constraint on activities after surgery = full return to your favorite activities, hobbies, sports – many patients can return to work in just few days
- Functional Surgery = effective, long-lasting relief, not having to deal with long-term convalescence of large wounds and extensive approaches
