The loose bag capsule around the shoulder joint becomes inflamed The bag then appears to tighten or shrink This tightening combined with the pain restricts the movement How common is it It is most common in people between the ages of 40 and 70 years A re placement shoulder joint designed at Newcastle University has helped to alleviate some of the painful problems associate with other types of artificial joints. The Newcastle designed joint has The Skeletal System: . Articulations. Articulations. Introduction. Joints. , or articulations, are connections between bones that may or may not permit movement.. Cartilage, fluid, or dense connective tissues is usually involved in holding joints together.. (Joints). Articulations. Body movement occurs at joints (articulations) where 2 bones connect. Joint . Structure. Determines direction and distance of movement (range of motion). Joint strength decreases as mobility increases. The “Moving” Part of Anatomy!. Introduction. Many major sports, activities and hobbies require us to be able to move around. These movements define us as human because we have a unique ability to move in the animal kingdom. The shoulder is an extremely complicated region of the body. Greater mobility . = . Greater Instability .

Joints with differing amounts of connective tissues. Some of these joints have limited movement but most are fixed and have no movement. Name the three articulations that constitute the shoulder girdle complex. . Describe how stability of the shoulder is maintained. . Recite the names of the four muscles that come together to form the rotator cuff. . – PATIENT INFORMATION LEAFLET WHAT IS SHOULDER INSTABILITY? The shoulder joint is a ball and socket joint like the hip. However, the shoulder joint is very shallow, which allows greater flexibility 138 PART I: ANTERIOR SHOULDER INSTABILITY – ANATOMY, DIAGNOSIS AND TREATMENT 139 ligament is shaped like a hammock, spanning the inferior aspect of the glenoid. It has an anterior and a posterior This great range of motion can also lead to several common problems affecting the shoulder joint. . In other words, the shoulder is built for motion, not stability.
