A SLAP tear is an injury to the labrum of the shoulder, which is the ring of cartilage that surrounds the socket of the shoulder joint. Injuries to the superior labrum can be caused by acute trauma or by repetitive shoulder motion.| orthoinfo.aaos.org
In shoulder replacement surgery, the damaged parts of the shoulder are removed and replaced with artificial components, called a prosthesis. The specific type of shoulder replacement performed will depend on the cause and extent of your shoulder damage.| orthoinfo.aaos.org
A shoulder separation is not truly an injury to the shoulder joint. The injury actually involves the acromioclavicular (AC) joint. The AC joint is where the collarbone (clavicle) meets the highest point of the shoulder blade (acromion).| orthoinfo.aaos.org
Injuries to the SC joint typically result from motor vehicle collisions or participation in collision sports like football. While these injuries can be painful, most are relatively minor and will heal well without surgery.| orthoinfo.aaos.org
Shoulder fractures most often involve the clavicle (collarbone), proximal humerus (top of the upper arm bone), or the scapula (shoulder blade). Shoulder dislocations can involve any of the three different joints that make up the shoulder.| orthoinfo.aaos.org
Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket. Once a shoulder has dislocated, it is vulnerable to repeat episodes. When the shoulder slips out of place repeatedly, it is called chronic shoulder instability.| orthoinfo.aaos.org
Simply defined, arthritis is inflammation of a joint. In an arthritic shoulder, inflammation causes pain and stiffness. This article looks at the five different types of arthritis that typically affect the shoulder and describes their treatment options.| orthoinfo.aaos.org
Your arm is kept in your shoulder socket by your rotator cuff. The rotator cuff is a group of four muscles that come together as tendons to form a covering around the shoulder. When one of these tendons is torn, it may be painful to lift or rotate your arm.| orthoinfo.aaos.org
Because so many structures make up the shoulder, it is vulnerable to many different problems and injuries. This article explains some of the common causes of shoulder pain and describes some general treatment options.| orthoinfo.aaos.org
