Muscular male Middle aged 50s
Biceps tendon rupture
26
Intervention for distal biceps tendon tear
Usually surgery
27
When do you begin ROM and strength for distal bicep tear?
After 6-8 weeks post op
28
Trauma, respective weight bearing on olecranon
Olecranon bursitis
29
``` Infection Pain with full passive elbow flex Active possible Painfree resisted tests Pain with palpation ```
Olecranon bursitis
30
Rest Avoid pressure/irritation Anti-inflammatory modalities
Intervention for olecranon bursitis
31
If youre doing an exercise but they’re not responding to it =
Tendinopathy
32
Nerve entrapment syndrome for ulnar
Cubital tunnel syndrome
33
3 syndromes for radial nerve
High radial nerve compression Posterior interosseous nerve (PIN) palsy Radial tunnel syndrome
34
Syndromes of nerve entrapment for median nerve
Pronator sydnrome | Anterior interosseous nerve (AIN) syndrome
35
Largest unprotected nerve
Ulnar nerve
36
Most important nerve for hand function
Ulnar nerve
37
1st and 2nd most common nerve entrapment
``` 1= carpal tunnel - median nerve 2= cubital tunnel - ulnar nerve ```
38
Caused by trauma- laceration or osteophyte, heterotropic bone
Cubital tunnels syndrome
39
Caused by overuse also: Repetitive elbow flex/exten Prolonged elbow flex Tight FCU muscle
Cubital tunnel syndrome
40
Unable to make a full fist PROM full and painless Grip weak Intrinsic atrophy of hand if chronic
Cubital tunnel
41
Claw hand deformity
Cubital tunnel
42
Visible sign of CUTS
Wartenbergs sign (pinky ABDucted)
43
Pain/parasthesia: medial elbow, forearm, hand Ulnar 1 1/2 fingers Sensation: decreased in ulnar nerve distribution
CUTS
44
Caused by increasing pain at night (sleeping posture)
CUTS
45
+ tests for CUTS
``` Elbow flexion test Pressure provocation Tinel’s Froments Pollocks ```
46
Guyons canal is injury to?
Ulnar nerve
47
``` Handlebar syndrome Loss of 3 and 4 lumbricals Loss of 1/2 FPB Claw hand Wartenbergs ```
Guyon canal injury
48
Entrapment results in a ganglion cyst | Triquetral-hamate joint
Ulnar nerve- guyons canal
49
Sensory and motor NOT affected | Only palmar side affected
Guyons canal
50
Dorsal sensory affected Motor affected of FCU and FDP - affects both palmar and dorsal side
Cubital tunnel syndrome
51
Proximal peripheral nerve injury
Radial nerve
52
Midshaft of humerus - contusion - fracture - weak muscle (innervated distal to injury so wrist, finger, thumb ext) - decreased sensation
Radial nerve
53
Examples of radial nerve injury syndromes
``` Saturday night palsy Crutch palsy Humeral shaft Fx Radial tunnel syndrome PIN Dorsal radial sensory nerve (wartenbergs) ```
54
Only sensory changes for ?
Radial nerve Sx distal to wrist
55
Compression/cast or local surgery DRUJ dislocation Repeat pronation/supination
Causes of radial nerve
56
``` Weak elbow flexors Loss supination with elbow extended Loss wrist ext Weak ulnar and radial deviation Loss MCP ext Loss ext and ABD of thumb ```
Saturday night palsy
57
Weak finger extensions | No sensation loss
PIN syndrom
58
Pain deep in forearm No sensory/motor loss R/O tennis elbow (below it)
Sx of radial tunnel syndrome
59
Crutch compression Missile injury Anterior shoulder dislocation Lipoma or other neoplasm
Axillary - high median nerve lesion
60
Stab wounds Sleep palsy near pec major tendon Tourniquets Humeral shaft Fx
Upper arm - high median nerve lesion
61
Repeated or resisted pronation | Resistance to isolated flex of PIP joint of long and ring fingers
Pronator syndrome Sx
62
Associated with paresthesias in median innervated fingers- tinel’s sign
Pronator syndrome
63
Mild or non weakness | Sensory loss - subjective sense of numbness
Pronator syndrome
64
``` Radial midshaft Fx Excessive exercise Idiopathic Direct trauma Brachial neuritis Anatomic anomalies ```
AIN causes
65
Martin Gruber anastomoses
Intrinsic hand muscles weak - median nerve
66
