What condition is characterized by inflammation of tendons caught within the shoulder joint?

Impingement syndrome is characterized by the inflammation of the tendons, particularly the rotator cuff tendons, that are trapped or "impinged" within the shoulder joint during arm movements. This condition occurs when there is reduced space under the acromion (a bony structure in the shoulder), leading to irritation and inflammation of the tendons. It can result from repetitive overhead activities or structural abnormalities in the shoulder.

In contrast, the other conditions listed do not primarily involve the inflammation of tendons within the shoulder joint. Osteofibrous dysplasia is a bone development disorder, osteogenesis imperfecta is a genetic disorder affecting bone strength and density, and osteomyelodysplasia refers to a congenital disorder affecting bone and marrow development. Understanding impingement syndrome is essential for the orthopedic technologist, as it often requires appropriate assessment and management strategies to alleviate pain and improve shoulder function.
