Mechanical compression

Introduction The pressing factor caused by the mechanical force acts on the body and exerts a certain influence on the structure and function of the body.

Cause

Compressive factors caused by mechanical forces inside and outside the body act on the body, causing pressure on the tissues and organs of the body.

Whether there is a pressing factor caused by mechanical force around the site where the body has pain or the tissue or organ with dysfunction, if it exists, it can be judged that the body is subjected to mechanical compression.

Differential diagnosis

1. Spinal nerve compression: The spinal nerve is a mixed nerve whose sensory fibers begin from pseudomonopolar neurons of the spinal ganglia. The central protrusion of the pseudo-monopolar neurons is rooted into the spinal cord; the peripheral protrusions are added to the spinal nerves, distributed in the skin, muscles, joints, and visceral receptors, etc., and the sensory impulses of the body and the internal organs are transmitted to the center. The motor fibers are composed of the anterior horn of the gray matter, the thoracolumbar lateral angle, and the axons of the parasympathetic nucleus motor neurons distributed in the striated muscle, smooth muscle, and gland. Compression of the spinal nerves can lead to numbness in the limbs and limited sensory and motor function.

2. Spinal cord compression: Spinal cord compression refers to a group of diseases in which the spinal cord, spinal nerve roots, and their supply vessels are compressed by lesions of various natures.

3, local tenderness: From an anatomical point of view, the bone plate is very thin, the skin covering this part is also very thin, the periosteal sensory nerve is also rich, so it is very sensitive to the pressure, often produces obvious tenderness.
