Shoulder arthritis is damage to the cartilage inside the shoulder joint. The shoulder has two joints. "Shoulder arthritis commonly refers to the bigger ball-and-socket joint named the glenohumeral joint after the bones it connects (glenoid and humerus). The cartilage covers both the ball (the humeral head) and the socket (the glenoid)".

Shoulder arthritis is usually caused by the gradual wear and tear of cartilage. Cartilage is found in each joint in the body. It is the covering of bones in joints in a manner similar to Teflon on the ball bearing. Cartilage can be described as a living, flexible tissue ranging from 2 millimeters up to 3 millimeters roughly the size of two or two sheets of cardboard. This creates a contact between bones soft. If the cartilage remains intact it is able to endure multiple rotations without causing scratching of the surface since it's smooth.

• Osteoarthritis of the Shoulder: Osteoarthritis is also known as degenerative joint disease. It is often associated with wear and tear related to aging. It can also affect other joints besides the shoulder and is the most common form of arthritis.
• Rheumatoid Arthritis of the Shoulder: Rheumatoid arthritis is an autoimmune disorder, which means your body attacks your own healthy cells, which may include the lining of the joint. This inflammatory arthritis can be present in both shoulders at the same time.
• Post-Traumatic Shoulder Arthritis: If your shoulder was fractured, dislocated or otherwise injured, you may develop post-traumatic arthritis.

• Pain in the shoulder joint: Pain in the shoulder joint is the major sign of arthritis. It can be present in the front, side or back of the shoulder. Some people have pain even when they are not using the arm, and some have pain only when using it. Arthritis pain can occur at any time of day and can be present with or without shoulder stiffness. Often the pain is worse with lifting, carrying heavy objects or after exercising. The pain can often radiate into the arm or, if severe, can radiate down to the elbow and wrist.
• Stiffness of the joint: Stiffness of the joint is another sign of shoulder arthritis progression. You may experience stiffness as a loss of range of motion in the shoulder. As the motion decreases, you may find that you can do fewer things with your arm, and these activities may be limited due to pain.
• Grinding, clicking or cracking (crepitus): Grinding, clicking or cracking (crepitus) may be felt since the surface of the cartilage is irregular with arthritis. It may or may not be painful. Sometimes the shoulder may “lock up.” Occasionally, because the surfaces are no longer smooth, you may feel the shoulder slide in certain positions.

To diagnose shoulder arthritis, your physician will perform a physical exam and ask you questions about your symptoms and medical history. The degree of arthritis and the amount of bone in the socket can be evaluated and confirmed with an X-ray or, if needed, with a CT scan.

Shoulder Fracture

According to shoulder fracture in South Delhi, Shoulder injury symptoms include pain in the front of your shoulder that may move around to the side of your arm and back of your neck. You may also notice that your shoulder feels weak, especially when reaching overhead or lifting something heavy. You might experience a clicking, popping, or grinding sensation in your shoulder. In severe cases, you may have trouble sleeping due to shoulder pain and tenderness
