Our shoulder joint is the most flexible and allows for the
widest range of motion of the body. This enables us to do our daily tasks like
writing and cooking and also sports like reaching for the next far spot in rock
climbing.
Just as it is the most flexible, it is also the most
susceptible to damage chronically over time due to overuse and age and also
from sports or accidents, such as a bad fall.
We provide diagnosis, treatment and managing Joint Pain related problems.
Anatomy of the
Shoulder
The collarbone (clavicle), the upper arm bone (humerus) and
the shoulder blade (scapular) are the 3 bones that make up the shoulder.
The head of the humerus fits into the glenoid, a rounded
hollow in the scapula. A synthesis of tendons and muscles keep the humerus
fixed in the glenoid. Rotator cuff are the tissues overlying the head of the
humerus to form a joint capsule, which keeps the humerus to the scapula and the
shoulder stable. A lubricant for the shoulder joint – synovial fluid – is
secreted from the inner layer of the joint capsule.
Causes of Shoulder Pain
A list of common reasons of shoulder pain are as follows:
·
Instability. When the head of the humerus is
pushed completely out of the shoulder socket due to a sudden impact, shoulder
dislocation results. A partial dislocation or subluxation is when the ball of
the humerus is only half out of the socket. Dislocations may happen repeatedly
when the muscles, ligaments and tendons around the shoulder become worn or
limp. Frequent dislocations and subluxations
can result in higher risk of arthritis. Repeated dislocations is also painful
when one moves his arm away from the body or raising it.
·
Rotator cuff injury. Tendinitis can be due to
over time use and ageing or acute heavy lifting or overhead arm movements
putting undue stress on the rotator cuff tendons and eventually tendinitis. As
a result of tendinitis, rotator cuff tearing have a higher probability of
occurrence and such tears can cause weakness to raise arm, regardless it is a
partial or complete tear.
·
Osteoarthritis (OA). OA usually happens after
injuries. It is a chronic condition of wear and tear of the cartilage that
buffer the ends of the bones. OA causes the bones to grind against each other,
resulting in loss of movement in the join, stiffness and pain.
·
Impingement syndrome. This is a condition when
the swollen tendons get pressed or caught by the edge of the shoulder blade. It
is due to rotator cuff tendinitis and is coined as the painful arc, resulting
as sharp pain experienced during movement or arm raising
·
Referred pain from the neck. Impingement of
nerves that passes through the shoulder to the arm and hand, such as prolapsed
intervertebral disc in the neck, can be a shoulder pain that stem from the
neck.
·
Bursitis. With movement, bursitis may result in
inflammation and pain in the Bursae. Small fluid-filled pockets that help in
buffering pressure points and reducing friction between the tendons or
ligaments and bones is called Bursae.
·
Fracture. The most common fracture areas in the
shoulder are the head of the humerus and the clavicle. It can be very painful
with bruises. A shoulder fracture happens after a fall or trauma.
·
Frozen shoulder. Frozen shoulder happens between
the ages of 40 to 60, and usually after a tendon tear, simple and small injury
or rotator cuff impingement. This condition is characterized by seriously restricted shoulder movement due
to a lack of synovial fluid to lubricate the joint, with abnormal bands of
tissue (called adhesions) growing out as a result. Frozen shoulder can be
self-healed over a period of three years.
Tests
With a detailed physical checkup of the shoulder and
thorough consultation, the following tests may be done to help in diagnosis:
Laboratory tests
Blood tests such as rheumatoid factor, full blood count or
inflammatory markers.
Imaging
Ultrasound scan. A good visualisation of the soft tissues
and is hence useful for diagnosing soft tissue injuries.
X-ray. A cheap and reliable way to diagnose many shoulder
issues. It is a two-dimensional view of the shoulder joint.
Magnetic resonance imaging (MRI) scan. This is the test with
the most details. It highlights the various blood vessels, tendons, rotator
cuff muscles, nerves and other soft tissues.
Computed tomography (CT) scan. This is a three dimensional
test that gives more detailed visualisation of some soft tissues and bones and
better than X-ray.
Signs and Symptoms
There are some early symptoms and warning signs accompanying
shoulder pain. Depending on the underlying causes, the severity and location may
vary:
·
“Pop” out feeling of the shoulder
·
Swelling
·
Inability and limited motion range to lift the
arm above the head
·
Stiffness
·
Fragility and insensitivity of the arm
Treatments for
Shoulder Pain
Treatments will depend on the diagnosis of shoulder pain:
Surgery
Possible procedures like total shoulder replacement, Bankart
repair for shoulder instability or arthroscopic rotator cuff repair may be
required, depending on the diagnosis.
Physiotherapy
Resistance training for the rotator cuff muscles
Straightening of shoulder, spine and neck postures
Exercises to improve the range of motion and relieving
stiffness
Intra-articular injections
An immediate yet short three months relief – Cortiosteroid
injections – for the severe shoulder pains.
Medications
Symptomatic relief using oral and topical painkillers
Oral supplements which can aid in reducing inflammation and
soft tissue degeneration Swelling and soft tissue degeneration reducing oral
supplements.
