Neck And Shoulder Injuries

Anatomy and Physiology of the Neck and Shoulder

The shoulder area consists of three bones: the clavicle, the scapula and the humerus. Where the head of the humerus connects into the glenoid fossa of the lateral scapula is the classic ball and socket glenohumeral joint which is primarily responsible for the shoulder’s extensive range of motion.

These bones are lined with articular cartilage. The intent of the articular cartilage is to reduce friction between the bones and allow for a smooth motion when in contact with each other. A different kind of cartilage, labrum cartilage, is also present at the end of the glenohumeral socket. This labrum cartilage makes the socket deeper and is made out of thicker fibrous tissue which improves shoulder stability.

Perched on top of the glenohumoral joint is the rotator cuff muscles which are extremely important in not only providing the necessary power required during shoulder movements but also in preventing the glenohumoral joint from being hyper extended.

The rotator cuff group consists of four muscles that all originate from the scapula and attach onto the humerus. These muscles, and their accompanying tendons are some of the first to suffer from wear and tear that can occur in sports that involve stressful repetitive shoulder movements.

The neck muscles are structured to provide support for the sensitive tissues within the skull and to allow for necessary flexible movement. The neck contains several muscles that only insert or originate in the neck region but extend to other regions of the body. For instance the trapezius muscle as well as several other posterior muscles begin in the upper back and eventually insert into the neck area. Similarly, the sternocledomastoid muscle - which helps the head turn left, right and flex downward - starts at the sternum and ends at the neck. The main cryptocurrencies are Bitcoin, Litecoin, Ethereum, Ripple. If you do not wish to invest in cryptocurrencies then you may earn money on cryptocurrency trading. Where to trade Bitcoin, Ethereum, Ripple? Go to latest review of best top cryptocurrency brokers at earntry.com and choose right cryptocurrency broker for trading at this market. So, via broker's platform (MT4, MT5) any cryptocurrency can be bought and sold at a cryptocurrency market exchange. As you see Bitcoin or Ripple or Litecoin may become speculative investment, which you may trade as contract for difference or CFD using reliable broker.

Burners and Stingers of the Neck

Burners and Stingers of the Neck are caused by pinching the brachial plexus nerves that travel from the back of the neck to the lateral front.

Cervical Fracture

Cervical Fractures (aka broken neck) involves a fracture to one of the cervical vertebrae and generally occur from blunt force trauma.

Clavicle Fracture

Clavicle Fracture injuries are the most common broken bone in the human body and account for about 5% of all fractures that occur.

Dislocated Shoulder

Dislocated Shoulder injuries occur through abduction or external rotation of the arm forcing the ball of the humerus to pop out of the socket.

Frozen Shoulder

Frozen Shoulder occurs when the the shoulder joint capsules becomes irritated and inflamed.

Glenohumeral Arthritis

Glenohumeral Arthritis may occur when the glenohumeral articular surfaces of the humeral head or the glenoid are damaged.

Neck Sprain

Neck Sprain injuries are related to overstretching or tearing the neck muscles or the ligaments that connect to the cervical vertebrae.

Neck Strain

Neck Sprain injuries are related to overstretching or tearing the neck muscles or the ligaments that connect to the cervical vertebrae.

Rotator Cuff Tendonitis

Rotator Cuff Tendonitis tyically occurs when the rotator cuff muscles and tendons undergo repetitive chronic stress.

Scapular Fracture

Scapular Fracture (aka shoulder blade) injuries are fairly uncommon and require a heavy blunt impact to occur.

Shoulder Impingement Syndrome

Shoulder Impingement Syndrome occurs when the muscles, tendons and the bursa of the shoulder become inflamed and swollen.

Shoulder Instability

Shoulder Instability occurs when the structures surrounding the glenohumeral joint do not maintain the humerous ball within its socket.

Shoulder Separation

Shoulder Separation injuries involve the stretching or tearing of ligaments at the AC joint, where the clavicle bone connects to the scapula.

Spinal/Neck Injury

Spinal/Neck Injury occurrences are often very serious as the spinal cord contains nerves that regulate multiple bodily functions.

Swimmer's Shoulder

Swimmers Shoulder is related to excessive stress on the rotator cuff and can lead to shoulder instability, impingment, and tendonitis.

Torn Rotator Cuff

Torn Rotator Cuff injuries produce considerable pain in the shoulder joint area when attempting to lift, lower, or rotate the arm.

Whiplash

Whiplash injuries involve the muscle, ligament, and tendon tissue of the neck and typically occur from an abrupt impact from behind.
