Upper Extremity Disorders

* Carpel tunnel syndrome
* Cubital tunnel syndrome
* Thoracic outlet syndrome
* Raynaud’s syndrome (white finger)
* Rotator cuff syndrome
* DeQuervain’s disease
* Tendinitis
* Tenosynovitis
* Trigger finger
* Ganglion cyst

Neurovascular Disorders

* Carpal Tunnel Syndrome
o Impingement of the median nerve caused by irritation and swelling of the tendons in the carpal tunnel
* Cubital Tunnel Syndrome
o Pressure on the ulnar nerve when the elbows are exposed to hard surfaces
* Thoracic Outlet Syndrome
o Compression of the blood vessels between the neck and shoulder caused by reaching above shoulder level or carrying heavy objects
* Raynaud’s Syndrome
o Also known as Vibration White Finger ; Blood vessels of the hand are damaged (narrowed) from repeated exposure to vibration for long periods of time

Tendon Disorders

* Rotator Cuff Syndrome
* DeQuervain’s Disease
o Combination of tendinitis and tenosynovitis
* Tendinitis
o Irritation of the tendon
* Tenosynovitis
o Irritation of the synovial sheath
* Ganglion Cyst
o Accumulation of fluid within the tendon sheaths

Tendinitis
Hand and Wrist
Common Occupational CTDs of the Upper Extremities
Carpal Tunnel Syndrome
Common Occupational CTDs
of the Upper Extremities
Raynaud’s Syndrome
Symptoms

o Numbness and tingling in the fingers during vibration exposure; may continue after exposure has been discontinued
o Blanching (whitening) of one fingertip because of a temporary constriction of blood flow
o Other fingers also blanch
o Intensity of pain & frequency of attacks increase in time

Common Occupational CTDs of the Upper Extremities
Symptoms include:

+ pain in the ring and little fingers
+ tingling in these areas
+ numbness in these areas

Cubital Tunnel Syndrome
Common Occupational CTDs of the Upper Extremities
Symptoms include:

+ the arms “falling asleep”
+ weakened pulse
+ numbness in the fingers

Thoracic Outlet Syndrome
Common Occupational CTDs of the Upper Extremities

Symptoms include:
o Pain when you bend the arm and rotate it outwards against resistance
o Pain on the outside of the shoulder possibly radiating down into the arm
o Pain in the shoulder, which is worse at night
o Stiffness in the shoulder joint.
