A tear in the disc ring may result in the release of chemicals causing inflammation, which can result in severe pain even in the absence of nerve root compression. Disc herniation is normally a further development of a previously existing disc protrusion , in which the outermost layers of the annulus fibrosus are still intact, but can bulge ...
The annular ligament (orbicular ligament) is a strong band of fibers that encircles the head of the radius, and retains it in contact with the radial notch of the ulna. [ 1 ] Per Terminologia Anatomica 1998 , the spelling is "anular", [ 2 ] but the spelling "annular" is frequently encountered.
[28] [29] This inflammatory molecule, called tumor necrosis factor-alpha (TNF), is released not only by the herniated or protruding disc, but also in cases of disc tear (annular tear), by facet joints, and in spinal stenosis. [24] [30] [31] [32] In addition to causing pain and inflammation, TNF may also contribute to disc degeneration. [33]
Take persistent knee pain, for example. Most doctors will start by ordering an MRI of your knee - which might show things like arthritis or a torn meniscus. But what you may not realize is that ...
In human anatomy, the annular ligaments of the fingers, often referred to as A pulleys, are the annular part of the fibrous sheathes of the fingers.Four or five such annular pulleys, together with three cruciate pulleys, form a fibro-osseous tunnel on the palmar aspect of the hand through which passes the deep and superficial flexor tendons.
When this occurs, blood is unable to flow out of the vagina, causing a back-up of blood and pain in the abdominal region and/or back. You might not know that you have an imperforate hymen until ...
The zona orbicularis and proximal hip joint capsule are poorly understood. Recent studies seem to confirm that the proximal to middle part of the articular capsule, including the zona orbicularis, acts biomechanically as a locking ring wrapped around the femoral neck and thus is a key structure for hip stability in distraction.
Pain along the inside of the elbow is the main symptom of this condition. Throwing athletes report it occurs most often during the acceleration phase of throwing. The injury is often associated with an experience of a sharp “pop” in the elbow, followed by pain during a single throw. [2]
