N: 1. collapse (n.): 1801, from collapse (v.). collapse (v.): 1732, from Latin collapsus, past participle of collabi “fall together,” from com- “together” (see com-) + labi “to fall, slip” (see lapse (n.)). The adjective collapsed is attested from c.1600, from Latin collapsus, and perhaps this suggested a verb. Related: Collapsing.
2. When a fracture leads to a vertebral body collapse of more than 50 percent, there is a risk of segmental instability. The spinal segments work together to enable weight bearing, movement, and support of the entire spine. When one segment deteriorates or collapses to the point of instability, it can produce pain and impair daily activities. The instability ultimately results in quicker degeneration of the spine in the affected area.
3. Syncope is a temporary loss of consciousness (fainting) that happens when the brain does not get enough oxygen. It comes on suddenly, only lasts for a short time and you recover fully within a short time. It is often called a blackout, faint or collapse. It isn’t the same thing as a seizure which causes jerking. It is important to seek medical attention if you suffer from syncope, as it may be due to a serious underlying problem. The most common causes are mentioned below.
