1

acromioclavicular joint
2
Q
C5 Dermatome
A
lateral aspect of the lower deltoid muscle
3
Q
C6 Dermatome
A
radial side of forearm
4

5
Q
C8 Dermatome

6
Q
T1 Dermatome
A
medial aspect of the antecubital fossa, proximal to medial epicondyle of the humerus
7
Q
Common Causes of Elbow Pain
A
- subluxation of the radial head
- medial epicondylitis
- lateral epicondylitis
- olecranon bursitis
8
Q
Subluxation of the Radial Head (Nursemaid’s Elbow)
A
- common in children
- cause: sudden pulling, falling and arm twisting
- radial head slips out from under the annular ligament and gets trapped in the radiohumeral joint
- presentation: arm close to body with elbow slightly flexed or fully extended with the forearm pronated
9
Q
Medial Epicondylitis (Golfer’s Elbow)
A
- cause: overuse injury from repeated motion
- acute or chronic inflammation of FLEXOR tendons due to some form of strenuous activity
- presentation: pain on medial elbow, tenderness with passive extension of the wrist, resisted flexion of wrist
10
Q
Lateral Epicondylitis (Tennis Elbow)
A
- cause: overuse injury from repeated motion, excessive hyperextension
- acute or chronic inflammation of EXTENSOR tendons due to incorrect stroke mechanisms
- presentation: lateral elbow pain, pain on palpation, tenderness with resisted wrist extension
11
Q
Olecranon Bursitis
A
- causes: inflammatory arthritis, trauma, hemorrhage, infection
- inflammation of the olecranon bursae which is located in the posterior aspect of the olecranon
- presentation: pain and swelling of olecranon
- bursitis vs elbow effusion – able to extend elbow without severe pain = bursitis, with pain = suggestive of effusion
12
Q
Common Causes of Hand and Wrist Pain
A
- Carpal Tunnel Syndrome
- De Quervain Tenosynovitis
- Trigger Finger
- Scaphoid Fx
- Boxer’s Fx
- Colle’s Fx
13
Q
Carpal Tunnel Syndrome
A
- condition that is caused by compression of the medial nerve
- risk factors: obesity, endocrine disorders (DM), repetitive movements/workplace factors, pregnancy, genetic, female,
- presentation: pain and paresthesia along the first 3 and a half digits
- specialty tests: Tinels, Phalens
14
Q
De Quervain Tenosynovitis
A
- recurrent inflammation of the tendon and synovial sheath covering extensor pollicis brevis and abductor pollicis longus
- causes: recurrent movements (new mothers picking up child), idiopathic
- presentation: radial wrist pain at base of thumb especially with movement of the thumb
- specialty exam: Finkelstein Test
15
Q
Stenosing Flexor Tenosynovitis (Trigger Finger)
A
- thickening of the flexor tendon which cause the first annular pulley to not work properly
- risk factors: over-use trauma, DM, autoimmune conditions
- presentation: pain, locking and clicking of MCP joint; common in the 5th and 6th decade of life; most common on ring finger
