[32] The mortality rate for people who develop cerebral involvement is about 25%, and of those who survive who had lead encephalopathy symptoms by the time chelation therapy was begun ...
This breaking causes wear debris to be formed. If the debris and/or surface subsequently undergo chemical reaction, i.e., mainly oxidation, the mechanism is termed fretting corrosion. Fretting degrades the surface, leading to increased surface roughness and micropits, which reduces the fatigue strength of the components.
Activation of trigger points may be caused by a number of factors, including acute or chronic muscle overload, activation by other trigger points (key/satellite, primary/secondary), disease, psychological distress (via systemic inflammation), homeostatic imbalances, direct trauma to the region, collision trauma (such as a car crash which stresses many muscles and causes instant trigger points ...

THRs are an effective means of treatment in the older population; however, in younger people, they may wear out before the end of a person's life. [22] Other techniques, such as metal-on-metal resurfacing, may not be suitable in all cases of avascular necrosis; its suitability depends on how much damage has occurred to the femoral head. [23]
