What is a herniated disk?
A defect vertebral disk cannot buffer anymore the high mechanical stress. This causes pain which again leads to protection and inactivity. This again weakens the back muscles which strengthen and stabilize the spinal cord. Due to to the lack of the protective function of the deep muscles, the nucleus pulposus has to evade the higher pressure caused by a partial strain e.g. lifting - especially in combination with a rotational movement. The defect annulus fibrosus also cannot hold the nucleus pulposus anylonger in its center and will be pushed towards the outside, mostly towards the spinal channel and the roots of the nerves.
If the the annulus fibrosus stays intact, it is a protrusion of the vertebral disk. However, if the annulus fibrosus breaks, then it is a prolapse of the vertebral disk.
The nucleus pulposus now tightens the space in the vertebral canal and the vertebral foramina. This causes pressure on the marrow or a vertebral foramen. Depending on the size of the herniated disk, the particular spinal nerve causes pain. And also: as bigger the the prolapse is as more pain is radiated into the back, later into the buttom, the legs and the feet.
Endoscopic removal of herniated disk
It is a closed, percutaneous surgery with the goal to remove the misplaced or torn off nucleus pulposus.
A local anesthesia is needed for this treatment.
- Herniated disk
- The nerve is pinched
- Endoscopic removal of the herniated disk
- After the removal the basis is freshed up
- A healthy blood circulation is started
- The annulus fibrosus cures within 6 weeks after the surgery
The healing
The adjacent vertebral body is freshened up by a special technique after removing the degenerative, extruded tissue of the nucleus pulposus. New tissue grows within 3 to 5 weeks! This healing if the vertebral disk can be demonstrated by nuclear sin tomography 3 month after the surgery.
Advantages of a endoscopic vertebral disk surgery
- conservative treatment
- better healing of the ripped vertebral disk
- no big scarring
- comfortable local anesthesia
- the patient can painlessly walk two hours after the surgery
- the patient can go home one day after the surgery
- fast return to the normal activities
- a very low relapse rate
- very low risk rate
