25
What muscles are involved in Lateral elbow tendinopathy
ECRB or EDC ( difficult to localize)
26
Pt w/ lateral elbow pain Point tenderness 1cm distal to lateral epicondyle Pain w/ Passive wrist flexion, gripping, and resisted wrist ext and finger ext What Dx could it be?
Lateral elbow tendinopathy
27
if the lateral elbow tendinopathy is not getting better what DDx could it be ?
Radial nerve entrapment of the PIN branch
28
__________ occurs in 50% of athletes competing in overhead sports
lateral elbow tendinopathy
29
What conditions can present similar to tennis elbow
Radial/PIN nerve entrapment Instability/stress at radio-capitellar joint
30
Pt w/ dull aching at medial elbow weak grip ulnar nerve paresthesia What Dx could it be ?
Medial elbow tendinopathy
31
Forceful work or overuse Valgus stress of pronator teres, FCR, and FCU
Medial elbow tendinopathy
32
What is the MOI of the distal biceps tendon rupture ?
Usually a single traumatic event involving resistance against arm w elbow in about 90 Flex
33
Which kind of bicep tendon rupture needs surgery immediately?
Distal if they have a proximal bicep tendon rupture they might opt not to get surgery since there is still another head of the muscle
34
What can cause cubital tunnel syndrome?
A valgus traction longstanding valgus deformity Sustained flexion postures (cyclists)
35
What nerve passes through the cubital tunnel
Ulnar nerve (note: 2nd most common nerve entrapment)
36
What is unique about Radial tunnel syndrome?
No sensory involvement ONLY MOTOR
37
How will radial tunnel syndrome present (what muscles are weak) what nerve is compressed
Compression of deep branch of radial N Deep extensor muscles of forearm weak (extensor indicis, extensor pollicis longus)
38
What is pronator teres syndrome? What nerve is compressed?
compression of MEDIAN nerve b/t heads of pronator teres muscle
39
How do you diagnose pronator teres syndrome
resisted pronation
40
A pt w/ anterior interosseus nerve syndrome cannot do what?
Make an OK sign (median nerve) FDP !!! (weak grip)
41
The anterior interosseus nerve supplies what muscles
Flexor pollicis longus (OK Sign) Pronator quad Flexor Digitorum profundus of 2 and 3 (OK sign)
42
Pt reports difficulty buttoning shirts, forming fist, gripping
Anterior interosseus nerve syndrome
43
T or F: anterior interosseus nerve syndrome will have sensory involvement
F
44
TTP over olcecranon process Pain w/ forced elbow extension increased valgus laxity
Valgus extension overload syndrome Common in gymnasts and baseball players usually has a bone bruise
45
What is panners disease
Osteochondrosis of humeral capitulum Usually occurs 7-10 years old (peak at 9) Repetitive valgus stress causing compression of radio-capitellar joint (limited blood supply)
46
T or F: Kids will not have panner disease, only adults
F, ONLY KIDS will have panner syndrome
47
What are the symptoms of panner disease
Fairly sudden onset of lateral elbow pain dull aching pain, worsened by motion absence of mechanical symptoms
48
What is the prognosis of panner disease
condition is self limiting probability of remodeling of joint is high long term disability is rare
49
What part of the body is affected by Osteochronditis Dissecans
Humeral capitulum
50
What is osteochonditis dissecans
subchondral head of bone begins to separate from humerus d/t repetitive valgus stress causing compression or w/ repeat ext and forceful pronation
51
Osteochondritis dissecans commonly affects who
throwers/gymnasts b/t 12-17
52
What is this XRAY showing
Cresent shaped region on humeral capitulum -> osteochondritis dissecans
53
T or F: Osteochondritis dissecans will get better on its own
F, needs PT
54
Gradual onset of lateral elbow pain Dull aching, worsened by motion Pt experiences locking/catching Mild/Moderate limitation of ext
Osteochondritis Dissecans
55
Pt tender at radio-capitellar jt Joint effusion crepitis gradual onset of lateral elbow pain locking/catching
Osteochondritis dissecans
56
What is little league elbow
Basket term covering a wide spectrum of pathologies all related to growth plate stresses
57
Pt fell on tip of elbow swelling Pt missing last bit of elbow flexion
Olecranon bursitis
58
What are some differential Dx for Olecranon Bursitis
Cellulitis Septic arthritis/Septic bursitis Elbow Sprain
59
Septic arthritis/Septic Bursitis is usually caused by ?
Staphylococcus aureus
60
Pt w/ swelling at elbow, missing last bit of elbow flexion, redness, recent abrasion
Cellulitis
61
Pt was recently sick, has pain at elbow joint, swelling
Potential septic arthritis
62
Cyclists who hold sustained postures are at risk of
Cubital tunnel syndrome
63
What Is the elbow flexion test
For ulnar nerve problems Hold wrist extension and elbow flexion for 3-5 minutes Positive if ulnar Parasthesia
64
If you suspect radial tunnel syndrome, you should test _______ muscles
Extensor Indicis and Extensor Pollicis Longus
65
Radial tunnel syndrome happens where
Between the heads of the supinator muscle (arcade of Frohse)
66
what this?
Pronator teres syndrome (median nerve)
67
