Microdiscectomy is a surgical procedure employed to relieve the pressure over the spinal cord and nerve roots, caused by a ruptured (herniated) intervertebral disc. A herniated disc, standard in the lower back (lumbar spine) occurs when the inner gelatinous substance of the disc escapes through a tear in the outer, fibrous ring (annulus fibrosis). This may compress the spinal cord or the surrounding nerves, resulting in pain, sensory changes, or weakness in the lower extremities.
A microdiscectomy is performed under general anesthesia. Your surgeon will make a small incision in the midline over your lower back. Through this incision, a series of progressively larger tubes are placed and positioned over the herniated disc. The affected nerve root is then identified. Your surgeon removes a small portion of the bony structure or disc material that is pressing on the spinal nerve using microsurgical techniques. The incisions are closed with absorbable sutures and covered with a dressing.
Following the surgery, patients will be discharged home on the same day or the next day. Post-operatively, patients are advised to increase their activity levels gradually. If required, physical therapy is started after four to six weeks of the surgery to improve strength and range of motion.
- Less muscle and soft tissue disruption.
- Shorter recovery time.
- Minimal postoperative pain and discomfort.
- Fewer risks of complications.
