A shoulder separation is an injury to the acromioclavicular joint on the top of the shoulder. The shoulder joint is formed at the junction of three bones: the collarbone (clavicle), the shoulder blade (scapula), and the arm bone (humerus). A shoulder separation occurs where the clavicle and the scapula come together.
A sprained thumb is an injury to a ligament, which is a soft tissue that connects bones to each other at the joints to keep it stable, as opposed to a thumb fracture (break) which is an injury to the bone. The ulnar collateral ligament is the most injured ligament in the thumb. This particular ligament connects the thumb to the hand on the side closest to your index finger.
A hyperextended elbow occurs when your elbow joint bends backward more than it should. This condition mostly happens in individuals involved in weight-bearing activities or contact sports.
Elbow pain can happen for various reasons, including when lifting objects. For example, repeatedly lifting heavy objects can cause repetitive strain injury.
The Arthritis Foundation estimates that about half of all women and a quarter of men will experience hand pain because of osteoarthritis — when the protective cartilage between bones wears down — by age 85. But there are ways to ease the ache.
