Selective Endoscopic Discectomy
- Designed to relieve pain caused by herniated discs pressing on nerve roots
- Removes only the protruding part of the damaged disc that is pressing on the nerve
- Treated using minimally invasive surgical technique
A cervical or lumbar spinal disc can become damaged from disease or injury. The damaged disc can herniate with a portion of the disc protruding into the spinal canal, apply pressure to nerve roots. The procedure is performed under local or epidural anesthesia, enabling the patient to leave the hospital the same day.
After the location of the disc protrusion is confirmed, a guide wire is inserted through a small incision to the affected disc. The surgeon uses a fluoroscope, or specially designed x-ray machine, to ensure that the route to the herniated disc is made in the correct location. An obturator tube, which is a tube that allows for the insertion and movement of endoscopic surgical instruments, is passed over the guide wire to push apart the tissue down to the disc and to move the nerve root out of the way. A working sleeve is placed over the obturator tube and positioned on the damaged disc. The guide wire and obturator are removed and an endoscope (small camera with a light) is placed through the sleeve. The surgeon uses the endoscope to guide the surgical tools and inspect the results. The protruding parts of the disc are removed, reducing the pressure inside the disc while the spine remains stable. The disc wall defect is treated with a laser and radiofrequency probe. The instruments are removed and a small bandage placed over the incision. Because our focus is on minimally invasive approaches, recovery times are generally quicker and patients often experience pain relief sooner rather than later.
