Normally, bone continuously breaks down and rebuilds—old bone is resorbed and replaced with new bone. The process keeps the skeleton strong and helps it to maintain a balance of minerals. [23] In the course of avascular necrosis, however, the healing process is usually ineffective and the bone tissues break down faster than the body can ...
A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture . [ 1 ]
Leakage of water into the breathing loop of a rebreather, which dissolves alkaline material used to chemically remove carbon dioxide from exhaled air. This contaminated water may move further along the breathing loop and reach the diver's mouth, where it may cause choking, and in the case of strong alkalis, caustic corrosion of the mucous ...
Examples of common causes in humans are traffic collisions and diving into shallow water. Abnormal movement of neck bones or pieces of bone can cause a spinal cord injury, resulting in loss of sensation, paralysis, or usually death soon thereafter (~1 min.), primarily via compromising neurological supply to the respiratory muscles and ...
When the subject was dropped, the head would be forced into hyperextension by the full weight of the body, a sufficient force to cause the fracture. Despite its long association with judicial hangings, one study of a series of such hangings showed that only a small minority of hangings produced a hangman's fracture. [5]
"Bones break because of either two main reasons. One, the force on the broken is stronger than the bone can take. Or two, the bone itself is weakened for some reason," said Dr. Claire Shannon, a ...
Most catastrophic injuries related to diving and swimming in the United States occur when an individual dives into shallow water. It is the cause of 2.6% of all cervical spine injury admissions, [21] and are chiefly sustained by recreational divers. The most common cause is diving into shallow water, inexperience, inadequate supervision, and ...
