In 1994 David Chalmers published a paper explaining why consciousness is such a challenging phenomenon to understand. Although he wasnât the first to discuss these challenges, he was the first to categorize them into two types of problems: âeasyâ problems and the âhardâ problem.
Rotator cuff tear arthropathy (or shoulder arthritis with a large rotator cuff tear) is a severe and complex form of shoulder arthritis in which the shoulder has lost not only the cartilage that normally covers its joint surface but also the tendons of the rotator cuff tear which help position and power the joint.enetics. Rotator cuff tear arthropathy (or shoulder arthritis with a large rotator cuff tear) is not known to be inherited although rotator cuff tears appear to be more common in individuals from families in which other members also have cuff tears.
The rotator cuff is a group of tough, flexible fibers (tendons) and muscles in the shoulder. Rotator cuff disorders occur when tissues in the shoulder get irritated or damaged. Rotator cuff disorders include: 1  Inflammation of the tendons (tendinitis) or of a bursa (bursitis).2  In the shoulder, a bursa is a small, fluid-filled sac that serves as a cushion between the tendons and the bones. 3  Impingement, in which a tendon is squeezed and rubs against bone.otator cuff disorders include: 1  Inflammation of the tendons (tendinitis) or of a bursa (bursitis). 2  Impingement, in which a tendon is squeezed and rubs against bone. 3  Calcium buildup in the tendons, which causes a painful condition called calcific tendinitis. 4  Partial or complete tears of the rotator cuff tendons.
