Shoulder Injuries

Injury Information

Shoulders have very few mechanoreceptors - the means by which the brain detects their position - hence the importance of providing overall support. ClaviBrace® in it's gilet form,

  • stabilises pelvis/hips
  • aligns spine
  • supports shoulders 

  • Specific Conditions
    Dislocated Shoulder (Mayo Foundation for Medical Education and Research)
    An injury in which your upper arm bone pops out of the cup-shaped socket that forms part of your shoulder blade. A dislocated shoulder is a more extensive injury than a separated shoulder, which involves damage to ligaments of the joint where the top of your shoulder blade meets the end of your collarbone.

    The collarbone or clavicle is horizontal on your shoulder, from the middle of the chest out towards the top of your shoulder. You have one on each side and you can feel it just underneath the skin. Its job is to act as a support strut for your shoulder and to help hold the arm in place.

    According to Wikipedia:

    • It is one of the last bones to finish ossification at about 21–25 years of age.
    • Even though it is classified as a long bone, normally the clavicle has no bone marrow cavity like other long bones.
    • The most commonly broken bone is the clavicle, accounting for 5% of all fractures seen in hospital emergency admissions.

    Fracture of the Shoulder Blade (Scapula) (American Academy of Orthopaedic Surgeons)
    Triangular, mobile, and protected by a complex system of surrounding muscles, the shoulder blade (scapula) is rarely broken. Scapula fractures represent less than 1% of all broken bones.

    Frozen Shoulder (Mayo Foundation for Medical Education and Research)
    Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by stiffness and pain in your shoulder joint. Signs and symptoms typically begin gradually, worsen over time and then resolve, usually within one or two years.

    Your risk of developing frozen shoulder increases if you're recovering from a medical condition or procedure that affects the mobility of your arm such as a stroke or a mastectomy.

    AC (Acromioclavicular) Joint Injuries (American Orthopaedic Society for Sports Medicine)
    The AC (acromioclavicular) joint is a joint in the shoulder where the collarbone (clavicle) meets the shoulder blade (scapula). The specific part of the scapula adjacent to the clavicle is called the acromion, hence the name AC joint. The most common problems that occur at the AC joint are arthritis, fractures and “separations.”

    Arthritis of the Shoulder (American Academy of Orthopaedic Surgeons)
    Although most people think of the shoulder as several joints, there are really two joints in the area of the shoulder.

    One is located where the collarbone (clavicle) meets the tip of the shoulder bone (acromion). This is called the acromioclavicular or AC joint.

    The junction of the upper arm bone (humerus) with the shoulder blade (scapula) is called the glenohumeral joint or scapulothoracic joint. Both joints may be affected by arthritis.

    To provide you with effective treatment, your physician will need to determine which joint is affected and what type of arthritis you have.

    Biceps Tendon Tear at the Shoulder (American Academy of Orthopaedic Surgeons)
    The biceps muscle is in the front of your upper arm. It helps you bend your elbow and rotate your arm. It also helps keep your shoulder stable. Tendons attach muscles to bones. Your biceps tendons attach the biceps muscle to bones in the shoulder and in the elbow. If you tear the biceps tendon at the shoulder, you may lose some strength in your arm and be unable to forcefully turn your arm from palm down to palm up.

    Many people can still function with a biceps tendon tear, and only need simple treatments to relieve symptoms. Some people require surgery to repair the torn tendon.

    Brachial Plexus Injury (Erb's Palsy) (American Society for Surgery of the Hand)
    The brachial plexus is a network of nerves that originate at the spinal cord in the neck and control the hand, wrist, elbow, and shoulder. Nerves are the electrical wiring system in all people that carry messages from the brain to the rest of the body. The brachial plexus has nerves that are both motor and sensory.

    Motor nerves carry messages from the brain to muscles to make the body move. Sensory nerves carry messages to the brain from different parts of the body to signal pain, pressure, and temperature.

    The network of nerves is fragile and can be damaged by pressure, stretching, or cutting.

    Chronic Shoulder Instability Dislocated shoulder or when your shoulder "Goes Out"
    (American Academy of Orthopaedic Surgeons)
    The shoulder is the most moveable joint in your body. It helps you lift your arm, rotate it and reach up over your head. It is able to turn in many directions. This greater range of motion, however, results in less stability.

    Shoulder instability occurs when the head of the upper arm bone is forced out of the shoulder socket. This can happen as a result of a sudden injury or from overuse.

    Once a shoulder has dislocated, it is vulnerable to repeat episodes. When the shoulder is loose and slips out of place repeatedly, it is called chronic shoulder instability.

    Rotator Cuff Injuries (Patient Education Institute)
    The combination of muscles and ligaments in the shoulder is called the ‘rotator cuff’. The rotator cuff is located under part of the shoulder blade.

    Rotator Cuff Tears (American Academy of Orthopaedic Surgeons)
    A torn rotator cuff will weaken your shoulder. This means that many daily activities, like combing your hair or getting dressed, may become painful and difficult to do.

    Shoulder Trauma (American Academy of Orthopaedic Surgeons)
    Trauma to the shoulder is common. Injuries range from a separated shoulder resulting from a fall onto the shoulder to a high-speed car accident that fractures the shoulder blade (scapula) or collar bone (clavicle). One thing is certain: everyone injures his or her shoulder at some point in life.

    Separated Shoulder (Mayo Foundation for Medical Education and Research)
    A separated shoulder is an injury to a part of one of your body's most mobile joints — the joint formed where the top of your shoulder blade meets the end of your collarbone. A separated shoulder is a stretch or tear of one or more of the ligaments supporting this joint.

    Shoulder Fractures: Clavicle, Scapula, Proximal Humerus (American Society for Surgery of the Hand)
    The shoulder is a joint suspended by many muscles surrounding the upper extremity. The shoulder bones include the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). (see Figure 1) The only connection of the shoulder girdle to the remainder of the skeleton is the clavicle. The scapula is an important part of the shoulder joint as it serves as an anchor for many muscles and contains the socket part of the shoulder (glenoid). The upper end of the humerus has a ball-like shape that articulates with the socket, and the humerus also serves as an attachment point for many muscles and tendons. One of the most important is the rotator cuff. Disruption of any of these parts can create difficulty with the function of the shoulder.

    Shoulder Impingement/Rotator Cuff Tendinitis (American Academy of Orthopaedic Surgeons)
    Your shoulder is made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle).

    Your arm is kept in your shoulder socket by your rotator cuff. These muscles and tendons form a covering around the head of your upper arm bone and attach it to your shoulder blade.

    There is a lubricating sac called a bursa between the rotator cuff and the bone on top of your shoulder (acromion). The bursa allows the rotator cuff tendons to glide freely when you move your arm.

    Shoulder Joint Tear (Glenoid Labrum Tear) (American Academy of Orthopaedic Surgeons)
    Advances in medical technology are enabling doctors to identify and treat injuries that went unnoticed 20 years ago. For example, physicians can now use miniaturized television cameras to see inside a joint. With this tool, they have been able to identify and treat a shoulder injury called a glenoid labrum tear.

    SLAP Tears (American Academy of Orthopaedic Surgeons)
    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.

    Tendonitis and Bursitis (American College of Rheumatology)
    Tendinitis or bursitis often involves the shoulder, elbow, wrist, hip, knee and ankle. The pain it causes may be quite severe and often occurs suddenly. As in arthritis, the pain is worse during movement. Unlike arthritis, the pain is often in parts of the body far from a joint.

    Tendinitis often results from repetitive use (overuse). Though the problem can recur or be chronic (long term) in some people, it is most often short term, mainly if treated early.

    Tendonitis of the Long Head of the Biceps (American Academy of Orthopaedic Surgeons)
    Long head of biceps tendonitis is an inflammation or irritation of the upper biceps tendon. This strong, cord-like structure connects the upper end of the biceps muscle to the bones in the shoulder.
