transforaminal endoscopic discectomy
A minimally invasive technique using endoscopic visualization through the neural foramen to remove herniated disc material.
Full Definition
Transforaminal endoscopic discectomy is a minimally invasive surgical technique for treating lumbar disc herniation using endoscopic visualization through a transforaminal approach. The procedure involves insertion of a specialized endoscope through the neural foramen, allowing direct visualization and removal of herniated disc fragments. This approach preserves normal spinal anatomy, requires only local anesthesia in many cases, and results in minimal tissue trauma. The technique is particularly useful for contained disc herniations and some cases of lateral recess stenosis, though patient selection criteria are more restrictive compared to traditional open discectomy.
Usage
Usage note: Specify approach (transforaminal vs interlaminar); emphasize patient selection criteria and limitations.
