A shoulder separation sounds like an odd injury, but in reality, it refers to the stretching or tearing of ligaments where the collarbone (clavicle) meets the shoulder blade (scapula). This intersection is also called the acromioclavicular or AC joint.
A gamekeeper's thumb, also called a skier's thumb, is an injury to one of the important ligaments at the base of the thumb joint. The injury involves the ulnar collateral ligament (UCL), a band of tough, fibrous tissue that connects the bones at the base of the thumb. This ligament prevents the thumb from pointing too far away from the hand.
Internal impingement is a specific type of shoulder injury that is seen primarily in throwing athletes.
Chondromalacia patellae is a term used to describe the damage or softening of the cartilage on the underside of the kneecap. It is similar to patellofemoral pain syndrome (runner's knee) in which the pain is felt under and around the kneecap. This condition is common among young athletics but may also occur in older adults who have arthritis of the knee.
Shoulder pain, stiffness or weakness can make it difficult to carry out everyday tasks, like reaching for something on a high shelf, driving a car or brushing your hair. If you have pain that won’t go away, it’s time to see a doctor.
