Also known as “wear-and-tear” arthritis, osteoarthritis is a condition that destroys the smooth outer covering (articular cartilage) of bone. As the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. During movement, the bones of the joint rub against each other, causing pain.
Osteoarthritis usually affects people over 50 years of age and is more common in the acromioclavicular joint than in the glenohumeral shoulder joint.

Biceps tendinitis is inflammation of the long head of the biceps tendon. In its early stages, the tendon becomes red and swollen. As tendinitis develops, the tendon sheath (covering) can thicken. The tendon itself often thickens or grows larger.
The tendon in these late stages is often dark red in color due to the inflammation. Occasionally, the damage to the tendon can result in a tendon tear, and then deformity of the arm (a “Popeye” bulge in the upper arm). Biceps tendinitis usually occurs along with other shoulder problems. In most cases, there is also damage to the rotator cuff tendon. Other problems that often accompany biceps tendinitis include:

Adhesive capsulitis (also known as Frozen shoulder) is a painful and disabling disorder of unclear cause in which the shoulder capsule, the connective tissue surrounding the glenohumeral joint of the shoulder, becomes inflamed and stiff, greatly restricting motion and causing chronic pain.
Bursae are thin, slippery sacs located throughout the body that act as cushions between bones and soft tissues. They contain a small amount of lubricating fluid that allows the skin to move freely over the underlying bone.
The olecranon bursa lies between the loose skin and the pointy bone at the back of the elbow called the olecranon.
Normally, the olecranon bursa is flat. If it becomes irritated or inflamed, more fluid will accumulate in the bursa and bursitis will develop.
Elbow instability is a looseness in the elbow joint that may cause the joint to catch, pop, or slide out of place during certain arm movements. It most often occurs as a result of an injury — typically, an elbow dislocation. This type of injury can damage the bone and ligaments that surround the elbow joint and work to keep it stable.
When the elbow is loose and repeatedly feels as if it might slip out of place, it is called recurrent or chronic elbow instability.
One of the most common physical complaints is shoulder pain. Your shoulder is made up of several joints combined with tendons and muscles that allow a great range of motion in your arm. Because so many different structures make up the shoulder, it is vulnerable to many different problems. The rotator cuff is a frequent source of pain in the shoulder.
What most people call the shoulder is really several joints that combine with tendons and muscles to allow a wide range of motion in the arm — from scratching your back to throwing the perfect pitch.
Mobility has its price, however. It may lead to increasing problems with instability or impingement of the soft tissue or bony structures in your shoulder, resulting in pain. You may feel pain only when you move your shoulder, or all of the time. The pain may be temporary or it may continue and require medical diagnosis and treatment.
This article explains some of the common causes of shoulder pain, as well as some general treatment options. Your doctor can give you more detailed information about your shoulder pain.
Tennis elbow, or lateral epicondylitis, is a painful condition of the elbow caused by overuse. Not surprisingly, playing tennis or other racquet sports can cause this condition. However, several other sports and activities can also put you at risk.
Tennis elbow is an inflammation of the tendons that join the forearm muscles on the outside of the elbow. The forearm muscles and tendons become damaged from overuse — repeating the same motions again and again. This leads to pain and tenderness on the outside of the elbow.
There are many treatment options for tennis elbow. In most cases, treatment involves a team approach.
