The common disease are :
- Shoulder Infections
- Rotator cuff tears
- Impingement syndrome
- Rotator cuff arthropathy
- Frozen shoulder
- Rheumatoid arthritis
- Recurrent dislocation
- Calcifying supraspinatus tendinitis
- Acromioclavicular joint osteoarthritis
- Glenohumeral joint osteoarthritis
1. Shoulder Infection :
- Proximal humerus – Here the infection is most commonly causes by the Staphylococcus osteitis.
- Gonococcal arthritis
- Tuberculosis of shoulder
2. Rotator cuff tears :
- This occurs around the shoulder joint, a tear in the tissues linking muscle to bone (tendons).
- People who perform the same shoulder motions frequently are more likely to develop a rotator cuff tear.
- Shoulder discomfort and weakness are common symptoms.
3. Impingement Syndrome :
- This is characterised by connective tissue like tendon, rubbing on a shoulder blade causes shoulder ache.
- Inflammation from repetitive shoulder activities causes impingement syndrome. Other factors include injury and ageing.
- The pain may be constant and worsen with lifting or reaching.
4. Rotator cuff arthropathy :
- Rotator cuff arthropathy is a type of degenerative joint disease in the shoulder caused by a rotator cuff tear that leads in aberrant glenohumeral wear and superior migration of the humeral head.
5. Frozen shoulder :
- Stiffness and soreness in the shoulder joint are symptoms of this illness.
- People with diabetes and those who have had their arm immobilised for a long time are more likely to develop the condition.
- Symptoms may appear gradually and fade away over the course of one or two years.
- Stretching and, on occasion, injections of corticosteroids and numbing medicine into the joint capsule are used to treat the condition. Surgery is sometimes done to release the joint capsule.
6. Rheumatoid arthritis :
- In this disease many joints, particularly those in the hands and feet, are affected by this chronic inflammatory condition.
- The body’s immune system destroys its own tissue, including joints, in rheumatoid arthritis. Internal organs are attacked in extreme cases.
- The linings of joints are affected by rheumatoid arthritis, which causes painful swelling.
- The inflammation associated with rheumatoid arthritis can lead to bone degradation and joint deformities over time.
7. Recurrent dislocation :
- Dislocations can occur repeatedly after the ligaments, tendons, and muscles surrounding the shoulder become loose or damaged. The inability of these tissues to maintain the arm centred in the shoulder socket is known as chronic shoulder instability.
8. Calcifying supraspinatus tendinitis :
- Calcific tendinitis of the supraspinatus tendon is the reactive calcification of the rotator cuff tendons and one of the main causes of acute shoulder pain in adults. It is commonly found in people aged 30–60 years and its incidence is reported at 2.7%–7.5%.
9. Acromioclavicular joint osteoarthritis :
- Acromioclavicular osteoarthritis is a kind of shoulder arthritis that causes pain, stiffness, and weakness in the front of the shoulder due to degenerative changes to the cartilage and other structures in the acromioclavicular joint.
10. Glenohumeral joint osteoarthritis :
- Degenerative shoulder (glenohumeral) osteoarthritis is marked by articular cartilage and subchondral bone degeneration, as well as glenohumeral joint constriction.
- With an estimated frequency of between 4% and 26%, it causes severe discomfort, functional limitations, and impairment.
