Sequelae of lumbar anesthesia.

Commonly known as half-body anesthesia and spinal anesthesia, the anesthesia is performed on the lower back and the midline of the spine. The needle for anesthesia is about 12G, with a diameter of about 0.15-0.2mm, which is relatively thick. During anesthesia, it penetrates the skin, subcutaneous tissue, supraspinous ligament, interspinous ligament, and ligamentum flavum in turn to reach the epidural space for injection. Anesthesia is used for epidural anesthesia, or further through the dura and arachnoid to the subarachnoid space for spinal anesthesia. This is the anesthesia method and operation. General lower extremity, perineal, pelvic, abdominal surgery can choose this type of anesthesia.

During the anesthesia process, the sharp and thick anesthesia puncture needle will definitely damage the skin, subcutaneous tissue, supraspinous ligament, interspinous ligament, and ligamentum flavum of the spine. Causes damage to the periosteum or bone of the vertebrae, or damage to the nerve roots. These injuries may cause lower back pain or pain in other related areas. However, these tissues are self-repairing and rarely leave sequelae, it just depends on the length of time for each person's physical recovery. The nerve root injury is indeed slower to heal itself, but unless it is completely cut off and the broken end is wrapped by other tissue, it will still grow well. If you still have foot pain symptoms after a month or two, it is recommended to go to an orthopedic or neurology department for a review, or you can consult an anesthesiologist.
