What is far lateral?
The `far lateral’ compartment is anatomically defined as the area lateral to the superior and inferior pedicles, with the disc situated anteriorly and the vertebral body and leading edge of the superior articular facet medially with the facet joint itself found dorsally.
What causes lateral disc herniation?
One biomechanical study revealed that combined motions of lateral bending, flexion, and axial rotation caused tear from the nucleus to posterolateral annulus, which suggested that unstable and asymmetrical spinal motions could lead to lateral disc herniation.
What are the types of disc herniation?
Three Basic Types of Herniated Discs
- Contained Herniation (Protrusion) Contained herniations are often referred to as “bulging discs.” They are caused when there is pressure between the vertebrae that causes the discs to protrude outward.
- Non-Contained Herniation (Disc Extrusion)
- Sequestered Herniation.
What are the four stages of disc herniation?
There are four stages: (1) disc protrusion (2) prolapsed disc (3) disc extrusion (4) sequestered disc. Stages 1 and 2 are referred to as incomplete, where 3 and 4 are complete herniations. Pain resulting from herniation may be combined with a radiculopathy, which means neurological deficit.
What is a far lateral decompression?
What is our minimally invasive far lateral lumbar discectomy? Our minimally invasive far lateral lumbar discectomy is a decompression procedure performed through a small incision. To perform the procedure, our surgeons use a series of dilating tubes to avoid excessive cutting and tearing of the surrounding muscles.
How do you treat a lateral herniated disc?
Reported methods to treat far-lateral herniations include complete facetectomy, the intertransverse technique, the pars technique, and the extraforaminal technique [2-3].
Which is worse bulging or herniated disk?
Herniated discs are considered more severe than bulging discs because they put significant pressure on nearby nerves, which can cause intense pain, inflammation and difficulties with movement.
What are the stages of disc herniation?
Disc herniation is pathologically divided into 4 stages of herniated nucleus pulposus: 1) bulging, 2) protrusion, 3) extrusion, 4) sequestration.
What’s an extraforaminal disc herniation?
Extraforaminal Herniated Disc Description. Far lateral herniated discs describe bulging intervertebral disc conditions in which the herniated portion of the structure exists outside of the spinal canal. This makes the condition innocent of causing central spinal stenosis, since it does not exist anywhere near the central spinal canal.
Can a herniated cervical disk paralize you?
A severely herniated disc can cause paralysis. Disc herniation is most common in the lower back (lumbar spine) and neck (cervical spine). Causes include age and sudden injury, such as from falling or heavy lifting. Treatment depends on how severe your symptoms are, how long you’ve had them and whether the disc is pressing on nerves or your spinal cord.
What is treatment for lumbar disc protrusion?
Massage therapy is a common alternative treatment for both disc protrusion and extrusion. Epidural steroid injections may be used to treat disc protrusions and extrusions. Sometimes caused by disc protrusion, sciatica can lead to pain and numbness down the leg. An extruded disc commonly occurs in the lower or lumbar spine.
What is Disk herniation?
Herniated Disk. Definition. Disk herniation is a rupture of fibrocartilagenous material (annulus fibrosis) that surrounds the intervertebral disk. This rupture involves the release of the disk’s center portion containing a gelatinous substance called the nucleus pulposus.
