• Grade III: coracoclavicular & AC ligaments ruptured w/ wide separation of joint
What are the treatment options for the various grades of AC separation?
• Grade I-II: sling, ice x 2 weeks then ROM

• Grade III:
- sling, ice x several weeks until pain subsides, then ROM
- surgical repair
What are causes of glenoid labrum injury?
• repeated anterior subluxation of the shoulder

• anterior instability during acceleration phase of throwing (secondary to long head of biceps pulling on anterior labrum

• repetitive bench pressing and overhead pressing

• fall on outstretched arm
What are findings on physical exam of a glenoid labrum injury?
• pain on forced external rotation @ 90 degrees abduction
• "pop" or "click" on forced external rotation
• weakness of rotator cuff muscles
What is the treatment of a glenoid labrum injury?
• physical therapy
• arthroscopic repair
What are the 4 muscles that make up the rotator cuff?
• supraspinatus
• infraspinatus
• subscapularis
• teres minor
What is the mechanism of injury for a shoulder dislocation?
• external rotation or abduction force on humerus
• direct posterior blow to proximal humerus
• posterolateral blow on the shoulder
What is the treatment for shoulder dislocation?
• closed reduction
• immobilzation in internal rotation
List 5 types of closed shoulder reduction
• stimson maneuver: pt prone on table with weight on arm
• mitch maneuver
• hippocratic maneuver: examiner places sole of foot in axilla
• traction/countertraction
• scapular manipulation: stimson maneuver with medial manipulation of the tip of scapula
What is treatment for bicipital tendonitis?
• physical therapy
• activity modifiation
What are causes of thoracic outlet syndrome?
• usually due to irritation of C8 and T1

• caused by:
- a cervical rib
- a fiber spanning from a rudimentary cervical rib
- tendinous bands from te scalenus anterior to the medius muscles
- hypertrophic clavicle fracture callus
What is the treatment for thoracic outlet syndrome?
• postural exercises
• surgical resection of cervical rib, first rib, or scalenotomy
What is the most common bone in the body fractured?
What is weakest part of the clavicle?
the junction of the middle and lateral thirds
Name and describe the 3 classes of clavicle fractures
• Class A - middle third fracture
• Class B - distal third fracture
• Class C - proximal third fracture
What is the most common mechanism of injury for a proximal humerus fracture?
A fracture of the humerus at the surgical neck can injure which nerve?
axillary nerve
A fracture of the humerus at the radial groove can injure which nerve?
radial nerve
A fracture at the distal end of the humerus can injure which nerve?
median nerve
A fracture of the humerus at the medial epicondyle can injure which nerve?
ulnar nerve
What is the treatment for midshaft humerus fracture?
• coaptation splint
• change to Sarmiento brace after 2 weeks
• may require ORIF w/ plate, screws, or nails
Which part of the humerus articulates with the radial head?
Which part of the humerus articulates with the ulna?
trochlea and olecranon fossa
What is a Monteggia fracture?
a fracture of the mid or proximal ulna with anterior dislocation of the radial head
What is a Galeazzi fracture?
a radial shaft fracture with associated dislocation of the distal radioulnar joint
What are signs of a radial head fracture on xray?
• sail sign
• fat pad sign
What is Tennis elbow?
• pain at the lateral humeral epicondyle, reproduced by extending the wrist against resistance
• seen in patients who perform repetitive wrist extension
What is Pitcher's elbow (or Golfer's elbow)?
• pain at the medial humeral epicondyle
• seen in patients who golf, or perform throwing sports, such as baseball, football, javelin
What 2 tendons form the snuffbox?
• extensor pollicis brevis tendon
• extensor pollicis longus tendon
What radiographic studies should be obtain for a possible scaphoid fracture?
• obtain AP/lat/obliq/scaphoid views
• plain xray may not demonstrate fx for up to 4 weeks
• if x rays are still negative at 10-14 days & pt is symptomatic, obtain bone scan for definitive diagnosis
What is the treatment for a scaphoid fracture?
• initially: thumb spica (always treat snuffbox tenderness, even if xray negative
