What do they do for this. It is some kind of operation done?
An annular rent refers to a partial tear in the outer layer of the intervertebral disc, while an annular tear involves a complete tear through the outer layer. Both conditions can result in back pain and may require medical intervention for relief.
An annular tear of the disc is, generally speaking, traumatic. However, over time, this can lead to degenerative disease of the affected disc or discs.
A left foraminal annular tear is when the annulus fibrosus rips or tears. The annulus fibrosus is the tough exterior of the intervertebral disc.
A posterior annular tear is a tear in the ligament fibers that cover the inner core of a disc. The discs separate each vertebra in your spine. A posterior annular tear in the L5-S1 discs indicates the location in which these tears occur. L5 is the fifth and lowest of the lumbar vertebra and the S1 is the first and highest sacral vertebra.

This description suggests there is a disc herniation at the level corresponding to the annular tear, pressing on the spinal cord or nerves. The disc material is protruding out of the disc space, causing compression of nearby structures. Symptoms may include back pain, leg pain, or neurologic deficits, and treatment options may include conservative management or surgical intervention.
The discs in-between the bones of the spine are composed of a tough and fibrous outer layer called the annulus fibrosis and a gelatinous inner layer called the nucleus pulposus. Sometimes that outer layer can tear, just like you can get a tear in any ligament or tendon in your body. When that tear occurs at the back fo the disc, but right in the center, it is called a central annular tear. If the tear is bad enough the inner material (nucleus pulposus), this is a herniated disc. L4-5 is the second to lowest disc in the spine, if this disc herniates out it can affect the L5 nerve root.
The bony spine is made up of bones which stack one upon another. These bones are called vertebrae. These vertebrae are separated from each other by discs. There is a disc between every 2 vertebrae. The discs are hockey-puck-shaped cushions with a capsule very much like nylon tape, filled with a jelly-like subsance (called the nucleus pulposus). A herniated disc is a disc which has a tear in the capsule, from which protrudes some of the jelly-like substance. An annular tear is a tear in the disc. This is what the radiologist says you have when he sees a tear in the disc but nothing protruding through it. The question of whether an annular tear can actually cause pain is controversial. Some authorities say it can, some say it can't.
The disc between two vertebra has two parts. One inside is softer than the one around it. This second one is called the annulus. There is a small tear in this part. The central section is also protruding (sticking out). Both are pressing on a spinal nerve. See the link below for a visual:
A herniation is the protrusion of muscle substance through a tear.
