Types of Shoulder Disorders, A Simple Guide To The Condition, Diagnosis, Treatment And Related Conditions

This book describes Shoulder Disorders, Diagnosis and Treatment and Related Diseases

The shoulder is really made up of 2 main joints that combine with tendons and muscles to permit a wide range of motion in the arm from scratching the back to throwing the perfect pitch.

The mobility of the shoulder has cause increasing problems with instability or impingement of the soft tissue or bony structures in the shoulder, resulting in pain.
The shoulder comprises 3 bones: the upper arm bone (humerus), the shoulder blade (scapula), and the collarbone (clavicle).

The head of the upper arm bone is placed into a rounded socket in the shoulder blade.

This socket is called the glenoid.

A combination of muscles and tendons keeps the arm bone centered in the shoulder socket.

These tissues are called the rotator cuff.

They enclose the head of the upper arm bone and attach it to the shoulder blade.

The shoulder is a ball-and-socket joint that comprises 3 main bones: the humerus (long arm bone), the clavicle (collarbone), and the scapula (also known as the shoulder blade).
The shoulder has many important parts:

1. The rotator cuff is a group of muscles and tendons that enclose the shoulder, giving it support and permitting a wide range of motion.
2. The bursa is a small bag of fluid that cushions and guards the tendons of the rotator cuff.
3. A cuff of cartilage termed the labrum produces a cup for the ball-like head of the humerus to move into.
4. The humerus goes relatively loosely into the shoulder joint.
   This supplies the shoulder a wide range of movement, but also makes it vulnerable to injury.

From Wikipedia These bones are enclosed by a layer of cartilage.

There are 2 main joints:

1. The acromioclavicular joint connects the highest part of the scapula and the clavicle.
2. The glenohumeral joint comprises the top, ball-shaped part of the humerus bone and the outer edge of the scapula.

This joint is also termed the shoulder joint.

The shoulder joint is the joint with the most movements in the body.

It moves the shoulder forward and backward.

It also permits the arm to move in a circular motion and to move up and away from the body.

Most shoulder disorders fall into 4 major types:

1. Tendon inflammation (bursitis or tendinitis) or tears of tendon
   Bursitis
   Acute Tendinitis
   Chronic tendinitis
   Tendon Tears
   Rotator cuff injury
   Shoulder impingement
2. Instability
   Subluxation
   Dislocation
3. Arthritis
   Osteoarthritis
   Rheumatoid arthritis
   Gout
4. Fracture (broken bone) or dislocation
   Acromioclavicular (AC) joint injury
   Cartilage tear
   Labral tear
   Frozen shoulder

Shoulder symptoms

1. Pain and stiffness happens in the shoulder that does not go away over months or years:
   Frozen shoulder, arthritis (osteoarthritis or rheumatoid arthritis)

2. Pain is often worse while using the arm or shoulder:
   Tendonitis, bursitis, impingement

3. Tingling, numb, weak, feels like it is clicking or locking:
   Shoulder instability, sometimes because of hyper mobility

4. Sudden very bad pain, inability to move the arm (or it is difficult), sometimes change of shape:
   Dislocation, fracture, torn or ruptured tendon

5. Pain on top of the shoulder:
   Disorders in the acromioclavicular joint, like dislocation or stretched or torn ligaments

Imaging tests, such as an X-ray or MRI, can provide detailed pictures of the shoulder to help with the diagnosis.

Some treatment methods are:

1. Physical or occupational therapy,
2. A sling or shoulder immobilizer, or
3. Medicines
4. Steroid injections
5. Surgery.
