About
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.
Procedure
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.
Postoperative Care
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.
Benefits
- Less muscle and soft tissue disruption.
- Shorter recovery time.
- Minimal postoperative pain and discomfort.
- Fewer risks of complications.
