A disc herniation or spinal disc herniation is an injury to the intervertebral disc between two vertebrae, usually caused by excessive strain or trauma to the spine. It may result in back pain , pain or sensation in different parts of the body, and physical disability .
This may occur when lifting or swinging a child by the arms. [2] The underlying mechanism involves slippage of the annular ligament off of the head of the radius followed by the ligament getting stuck between the radius and humerus. [1] Diagnosis is often based on symptoms. [2] X-rays may be done to rule out other problems. [2]
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.
The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament.
Annular ligament may refer to: Annular ligament of femur; Annular ligaments of fingers; Annular ligament of radius; Annular ligament of stapes (also known as the ...
The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament. The deepest point in the fovea is not axi-symmetric with the long axis of the radius, creating a cam effect during pronation and supination.

While primarily caused through natural wear and tear and degeneration, facet syndrome can also occur as a result of injury to the spine, or lifestyle choices. These causes can include: [citation needed] Osteoarthritis; Spondylolisthesis; Obesity; Smoking; Malnutrition; Trauma such as a car accident, fall or sports injury.
