Shoulder
Pain and Problems
What
is the shoulder?
The shoulder is made up of several
layers, including the following:
- Joints - facilitate movement, including the following:
- Sternoclavicular joint (where the clavicle meets the
sternum)
- Acromioclavicular (AC) joint (where the clavicle meets
the acromion)
- Shoulder joint (glenohumeral joint) - a
ball-and-socket joint that facilitates forward, circular, and backward
movement of the shoulder.
- Ligaments - a white, shiny, flexible band of fibrous
tissue that binds joints together and connects various bones and
cartilage, including the following:
- Joint capsule - a group of ligaments that connect the
humerus to the socket of the shoulder joint on the scapula to stabilize
the shoulder and keep it from dislocating.
- Ligaments that attach the clavicle to the acromion
- Ligaments that connect the clavicle to the scapula by
attaching to the coracoid process
- Acromion - the roof (highest point) of the shoulder
that is formed by a part of the scapula.
- Tendons - the tough cords of tissue that connects muscles
to bones. The rotator cuff Tendons are a group of tendons that connect the
deepest layer of muscles to the humerus.
- Muscles (to help support and rotate the shoulder in
many directions)
- Bursa - a closed space between two moving surfaces that
has a small amount of lubricating fluid inside; located between the
rotator cuff muscle layer and the outer layer of large, bulky muscles.
- Rotator cuff - composed of tendons, the rotator cuff
(and associated muscles) holds the ball of the glenohumeral joint at the
top of the upper arm bone (humerus).
Shoulder pain may be localized in a
specific area or may spread to areas around the shoulder or down the arm.
What
are some of the different types of shoulder problems?
Common shoulder problems include the
following:
- Dislocation
The shoulder joint is the most frequently dislocated major joint of the body - often caused by a significant force that separates the shoulder joint's ball (the top rounded portion of the upper arm bone, or humerus) away from the joint's socket (glenoid).
·
Separation.
The shoulder becomes separated when the ligaments attached to the collarbone (clavicle) are torn, or partially torn, away from the shoulder blade (scapula). Shoulder separation may be caused by a sudden, forceful blow to the shoulder, or as a result of a fall.

- Bursitis
Bursitis often occurs when tendonitis and impingement syndrome cause inflammation of the bursa sacs that protect the shoulder. - Impingement syndrome
Impingement syndrome is caused by the excessive squeezing or rubbing of the rotator cuff and shoulder blade. The pain associated with the syndrome is a result of an inflamed bursa (lubricating sac) over the rotator cuff, and/or inflammation of the rotator cuff tendons, and/or calcium deposits in tendons due to wear and tear. Shoulder impingement syndrome can lead to a torn rotator cuff. - Tendonitis
Tendonitis of the shoulder is caused when the rotator cuff and/or biceps tendon become inflamed, usually as a result of being pinched by surrounding structures. The injury may vary from mild inflammation to involvement of most of the rotator cuff. When the rotator cuff tendon becomes inflamed and thickened, it may become trapped under the acromion. - Rotator cuff tear
A rotator cuff tear involves one or more rotator cuff tendons becoming inflamed from overuse, aging, a fall on an outstretched hand, or a collision. - Adhesive capsulitis (frozen shoulder)
Frozen shoulder is a severely restrictive condition frequently caused by injury that, in turn, leads to lack of use due to pain. Intermittent periods of use may cause inflammation and adhesions to grow between the joint surfaces, thus restricting motion. There is also a lack of synovial fluid to lubricate the gap between the arm bone and socket that normally helps the shoulder joint to move. This restricted space between the capsule and ball of the humerus distinguishes adhesive capsulitis from the less complicated condition known as stiff shoulder. - Fracture
A fracture is a partial or total crack or break through a bone that usually occurs due to a impact injury.
What
causes shoulder problems?
Although the shoulder is the most
movable joint in the body, it is also an unstable joint because of its range-of-motion.
Because the ball of the upper arm is larger than the socket of the shoulder, it
is susceptible to injury. The shoulder joint must also be supported by soft
tissues - muscles, tendons, and ligaments - which are also subject to injury,
overuse, and under use.
Degenerative conditions and other
diseases in the body may also contribute to shoulder problems, or generate pain
that travels along nerves to the shoulder.
How
are shoulder problems diagnosed?
In addition to a complete medical
history and physical examination (to determine range-of-motion, location of
pain, and level of joint instability/stability), diagnostic procedures for
shoulder problems may include the following:
- X-ray - a diagnostic test which uses invisible
electromagnetic energy beams to produce images of internal tissues, bones,
and organs onto film.
- Arthrogram - a test in which dye is injected into the
shoulder joint and x-rays are taken to outline structures of the shoulder.
When the fluid leaks into an area that it does not belong, disease or
injury may be considered, as a leak would provide evidence of a tear,
opening, or blockage.
- Magnetic resonance imaging (MRI) - a diagnostic
procedure that uses a combination of large magnets, radiofrequencies, and
a computer to produce detailed images of organs and structures within the
body; can often determine damage or disease in a surrounding ligament or
muscle.
- Computed tomography scan (Also called a CT or CAT
scan.) - a diagnostic imaging procedure that uses a combination of x-rays
and computer technology to produce cross-sectional images (often called
slices), both horizontally and vertically, of the body. A CT scan shows
detailed images of any part of the body, including the bones, muscles,
fat, and organs. CT scans are more detailed than general x-rays.
- Electromyogram (EMG) - a test to evaluate nerve and
muscle function.
- Ultrasound - a diagnostic technique which uses
high-frequency sound waves to create an image of the internal organs.
- Laboratory tests (to determine if other problems may be
the cause)
- Arthroscopy - a minimally-invasive diagnostic and
treatment procedure used for conditions of a joint. This procedure uses a
small, lighted, optic tube (arthroscope) which is inserted into the joint
through a small incision in the joint. Images of the inside of the joint
are projected onto a screen; used to evaluate any degenerative and/or
arthritic changes in the joint; to detect bone diseases and tumors; to
determine the cause of bone pain and inflammation.
Treatment
of shoulder problems:
Specific treatment of shoulder
problems will be determined by your physician based on:
- your age, overall health, and medical history
- extent of the condition
- your tolerance for specific medications, procedures, or
therapies
- expectations for the course of the condition
- your opinion or preference
Treatment may include:
- activity modification
- rest
- physical therapy
- medications
- surgery
