Who is a candidate?
Tubular decompression may be considered for nerve compression from a herniated disc or from spinal stenosis at one or two levels, where the compression can be reached and fully relieved through a small corridor. It is less suitable where there is significant instability, deformity, or narrowing across many levels, situations in which a more extensive operation may be the more reliable choice.
How the procedure works
Through an incision of roughly two to three centimeters, a series of dilators gently spread the muscle fibers apart, and a tube is docked onto the bone. Working through that tube with a microscope or endoscope, the surgeon removes the bone, ligament, or disc material pressing on the nerve. Because the muscle is separated rather than cut and stripped, it falls back into place when the tube is removed.
Recovery
Many of these procedures are done as day surgery. Walking starts the same day. Leg pain frequently improves quickly, while back soreness at the incision settles over one to two weeks. Lifting and bending are limited for a short period, and physical therapy is introduced once the early soreness has passed.
Benefits and alternatives
The intended benefits are less muscle disruption, less post-operative pain, and a quicker early recovery compared with a traditional open decompression, while achieving the same goal of taking pressure off the nerve. Alternatives include continued non-operative care, injections, endoscopic decompression, open decompression, or decompression with fusion where there is instability.
Risks
Risks include infection, bleeding, a tear in the lining around the nerves, nerve injury, recurrence of the disc herniation, and the possibility that symptoms do not fully resolve. As with any minimally invasive approach, there is a small chance the operation needs to be converted to a larger exposure to complete it safely.
