In chemical pneumonia, inflammation of lung tissue is from poisons or toxins. Only a small percentage of pneumonias are caused by chemicals. Many substances can cause chemical pneumonia, including liquids, gases, and small particles, such as dust or fumes, also called particulate matter. Some chemicals only harm the lungs; however, some toxic materials affect other organs in addition to the lungs and can result in serious organ damage or death.
The shoulder joint can be replaced by an artificial shoulder or shoulder replacement for pain caused by arthritis or when the shoulder is severely fractured or broken. Arthritis is when the cartilage on the ends of the bones is gone and there is bone rubbing on bone in the joint.
I have summarized the results of this survey below. The first group of activities were recommended by more than half of the surgeons. The second group were recommended by less than half of the surgeons. The reasons that surgeons restrict activities after a total shoulder replacement were not analyzed in this study. We can surmise that one reason may be concern about failure of the polyethylene glenoid component.
