Tearing of the extensor carpi radialis brevis origin.

Somtimes this may extend to the extensor-digitorum-communis

53
Q

Cause/etiology lateral epicondylitis

A

Referred to histologically as an angiofibroblastic hyperplasia. Repetitive and forceful wrist extension, radial deviation and supination are most common causes. Seen often with tennis players, weavers, plumbers, and meat cutters.

54
Q

Evaluation/assessment lateral epicondylitis

A

Tenderness on the lateral aspect of the epicondyle at the origin of the ECRB on palpation

Positive cozen and mill maneuvers. Chair lift test.

X-ray may show calcification in 25% of cases

55
Q

Management lateral epicondylitis

A

Acute phase responds well to ice while splinting and myofascial release techniques are also indicated

Chiro adjustments, cross friction massage and mobilization are recommended in subacute phase. Rehab to include stretching adn strengthening.

Bracing during the sub-acute phase while playing tennis helps and modification of equipment is recommended

Co-manage approaches might recommend topical nitric-oxide application

56
Q

A

Medial elbow pain after repetitive activity such as hammering or using a screwdriver. Golfing or throwing can also cause symptoms and weakness on gripping is common

57
Q

Anatomy/structures medial epicondylitis

Medial epicondyle pain with an accompanying tendinopathy of the wrist flexors adn pronator teres. Ulnar nerve neuropathy may coexist with medial epicondylitis.

58
Q

A

Pain on wrist flexion and pronation from overuse, repetitive motions or athletic pursuits like golf. Tendinitis of the wrist flexors adn pronator teres results

59
Q

Evaluation medial epicondyltisi

A

During activity from teh sub-acute phase onwards

Mills and cozen are positive for lateral

Golfer and reverse mill test positive for medial epicondylitis

Tinel might be positive if ulnar nerve is involved

Elbow flexion contractures can occur in chronic cases, leading to restricted motion in extenstion and supination

X-ray may reveal calcifications over teh medial epicondyle in 20-30% of patients.

60
Q

Management medial epicondylitis

A

Acute phase - ice and rest - if flexor group involved, splinting in 10 degeres of flexion may relieve tension. If flexor carpi radialis is involved splinting in 10 degrees of radial deviation is recommended.

Myofascial release of flexor muscle mass and pronator teres is very effective

Cross friciton massage and mobilization is good for sub-acute phase

Chiro adjustments during subacute phase

Elbow braces will be effective

61

Traction forces,
cubitus valgus, subluxating ulnar nerve
Elbow synovitis (edema)

Anatomy/structures posterior impingement syndrome

A

Olecranon trochlea and olecranon fossa compression

70
Q

Cause/etiology posterior impingement syndrome

Osteophytes and loose bodies will form in some cases

71
Q

Evaluation posterior impingement syndrome

A

Active and passive extension displays an end range blockage with pain

Valgus extension overload test will be positive with crepitus and grinding

X-ray shows cartilaginous loose bodies on axial or cubital tunnel views

72

Damage to the annular ligament with radial head tenderness. The radial head is not fully formed

75
Q

Cause/etiology nursemaid’s elbow

A

Entrapment/rupture of the annular ligament by a forceful distraction/rotation. Radial head under-formation predisposes annular ligament damage.

76
Q

Evaluation nursemaid’s elbow

A

Immense pain without an obvious trauma such as a fall or blow to the elbow is indicative. Palpation will reveal a misplaced or mal-positioned radial head.

77

Chiro extremity assessment and adjustment

78
Q

Adolescent baseball pitcher complaining of medial or lateral elbow pain

A

Little league elbow

79
Q

Anatomy/structure little league elbow

A

Medial pain is due to injury of the medial anterior oblique ligament and fragmentation of the medial epicondylar epiphysis. Lateral pain is associated with degrees of radial head injury and growth plate immaturity. An osteochondritis dessicans of the capitellum is indicative of a lateral elbow injury.

80
Q

Cause/etiology little league elbow

A

Actually a syndrome

Repetitive valgus stress incurred while pitching causes a stretch injury to the medial elbow and compression injury to the lateral elbow

81
Q

Tenderness at both medial and lateral aspects of the elbow. Supination and pronation alternatively whether performed actively or passively can cause a palpable click or audible crepitus at the head of the radius (osteochondritis dissecans)

A

Little league elbow

82
Q

Little league elbow evaluation

A

Flexion contracture evident on passive ROM. Popping, clicking, and locking might occur on full-range active movment.

X-ray special views are required to see proper structures. Would order radial head-capitellum and valgus stress view

83
Q

Little league elbow management

A

Modification of activity is highly recommended if x-ray appears normal while clinical signs confirm. This would include proper mechanics training and teaching while avoidance of certain types of throws.

Acute pain modalities during the initial phase and proper warm up and stretching before resuming activity

Chiro adjustments to assist in resotring proper bio-mechanical fucntion.

84
Q

Young male complaining of one sided (dominant) arm pain and stiffness. Usually a sports related injury with a history of excessive throwing. Clicking and locking is associated

A

Osteochondrosis (panner’s disease)

85
Q

Anatomy/structures involved osteochondrosis/panner’s

A

Involves the capitellum of the elbow, more exactly the chondro-epiphysis. There is a decrease of blood supply to the structures causing avascular necrosis.

86
Q

Cause/etiology osteochondrosis/panner’s disease

A

Trauma or repetitive strenuous motion results in a disturbance of blood circulation to the cartilaginous epiphysis of the capitellum. Avascular necrosis results leading to deformity.

87
Q

Evaluation osteochondrosis

A

Elbow pain in children should often indicate necessity for x-rays following history of repeated weight bearing or excessive throwing.

Diagnosis for panner’s is largely radiographic - radial head capitellum and oblique views are essential. Fragmentation or loose bodies will be a clear indicator

88
Q

Management osteochondrosis (panner’s disease)

A

Best prognosis is with an open epiphysis
Rest and elimination of activity is required with splinting indicated
Stretchign and strengthening after acute phases subsides
Loose bodies and fragments if evident might need surgical removal if elbow locks
Chiro adjustments to help recuperation/recovery

89
Q

Swelling and redness just distal tot eh point of elbow. Following fall/trauma/repetitive activity injury such as wrestling

A

Olecranon bursitis

90
Q

Anatomy/structures involved olecranon bursitis

A

Olecranon bursa is injured/inflamed

91
Q

Cause/etiology olecranon bursitis

A

Olecranon bursa is injured following dragging or fall on the elbow resulting in the cushion like structure becoming inflamed, irritated, or infected.

92
Q

Evalutation olecranon bursitis

A

The large, egg sized swelling on the point of the elbow is hard to miss. Gout associated with kidney disease must be ruled out on history. Infection is distinguished if a visible wound is noticeable or if the site is warm and more tender than traditional bursitis.

93
Q

Management olecranon bursitis

A

Protection with a donut shaped support

Ice and pulsed US are indicated and very effective espeicially when chrnoic

Medical aspiration and excision might at times be necessary and if infectied would require immediate referral.

94
Q
