Composed of the glenohumeral joint and the acromioclavicular joint, the shoulder is vulnerable to injuries when overused, overstressed or aged. The glenohumeral joint is a ball-and-socket-type joint located atop the arm bone and shoulder blade socket. The acromioclavicular joint assists the glenohumeral in allowing the shoulder to be fully functional. Bones comprising these two joints are the humerus, scapula and clavicle.
Most shoulder conditions causing joint pain involving the following:
Bursae are tiny sacs of fluid that act as cushions between shoulder bones and soft tissues lying above the bones. When bursae are irritated by excessive use of shoulder ligaments and tendons, they become inflamed, swell and deteriorate rapidly. Without bursae sacs functioning normally, your shoulder bones will scrape against each other, producing throbbing pain and soreness.
If inflamed bursae between your rotator cuff and an area of the shoulder blade called the acromion is causing your shoulder to ache, your shoulder pain doctor in Staten Island may diagnose you with subacromial bursitis. This condition is often accompanied by rotator cuff tendinitis that may not have been diagnosed previously.
Tendons are tough, thick, cord-like tissues that connect muscles to bones. When tendons experience wear and tear due to excessive overuse, they eventually deteriorate, split and cause chronic pain when activated by certain motions. Acute shoulder tendinitis is typically seen in athletes or people who repetitively perform overhead activities. Chronic shoulder tendinitis emerges from degenerative diseases such as arthritis or simple aging. Shoulder tendons affected by tendinitis are usually your rotator cuff tendons and biceps tendons. Your shoulder doctor in Staten Island may suggest minimally invasive surgery if your rotator cuff tendons are affected by tendinitis.
If the acromion (top of the shoulder blade) puts strong pressure on the acromion’s underlying tissues when you lift your arm away from your body, you may be diagnosed with shoulder impingement. Pain and restricted motion occurs when the acromion “impinges” or scrapes against bursae and rotator cuff tendons. Untreated shoulder impingement may lead to tendinitis and/or bursitis and, eventually, a serious rotator cuff tear.
Your shoulder joint pain doctor in Staten Island will suspect shoulder instability if it appears the head of your upper arm bone has been forced out your shoulder socket. Overuse and/or sudden trauma can cause shoulder instability, pain, weakness and restricted movement.
You may suffer repeated shoulder instability or dislocation when tendons, muscles and ligaments become loosened or torn. Repeated instances of shoulder dislocation/instability may also promote development of arthritis in your shoulder joint.
Fractures of the shoulder usually involve the humerus (upper arm bone), your clavicle or your shoulder blade (scapula). Older people are especially prone to suffering shoulder fractures due to frequent falls. Auto accidents and playing impact sports are additional reasons a shoulder doctor in Jersey City diagnoses shoulder fractures in patients. Severe pain, noticeable swelling and deep bruising around your shoulder may indicate a fracture.
Less common causes of shoulder joint pain are infections, tumors and neuropathy. To ensure you receive an accurate diagnosis regarding your shoulder pain, call Regional Orthopedic today to make an appointment with a skilled shoulder joint pain doctor in NYC.
