Shoulder inspection presents with: Arm adducted, internally rotated, ant. shoulder is flat, prominent Humeral had. what type of dislocation do you suspect?
Posterior Glenohumeral dislocation
Anterior Glenohumeral dislocation shoulder presentation includes?
Arm abducted, Externally rotated, inferior humeral head, deltoid contour loss.
Which shoulder dislocation is more common, Anterior or posterior?
Anterior is the MC type
a compression fracture of the humeral head groove.
impact against glenoid.
Hill-Sachs Lesion
A bank-Hart lesion is a fracture of the what?
Inferior Glenoid rim fracture
Posterior Glenohumeral shoulder dislocation is most common associated with what injury (s)?
Seizures, Electric shock, or trauma
What must you rule out with and Anterior shoulder dislocation?
Must rule out Axillary nerve injury (Sensation over deltoid)
Most helpful view to differentiate Posterior v.s Anterior dislocation?
Axillary and Y view
Anterior deltoid pain w decreased ROM w overhead activities, external rotation, or abduction.
Combing hair, wallet reach, can’t sleep on affected side.
(+) Drop arm test, Neer’s, Jobe’s Tx:
Rotator Cuff Injury (SITS)
Tx: NSAID, Rest, wall climbs (PT)
As a result of Direct blow to an adducted shoulder leads to ?
Acromioclavicular Joint Dislocation
Class of AC dislocation where there is significant widening of AC/CC space?
Class III AC separation with CC involved (both rupture)
Class of AC dislocation where there is slight widening@ AC space?
Class II Only AC rupture
Classes of AC/CC dislocations that require surgery?
Class III-V (Otherwise sling, Ice, analgesia)
Humeral fracture where patient may develop wrist drop?
Must R/O Radial Nerve injury
Humeral shaft fracture
Proximal or Humeral head fractures requires to R/O injuries to what area?
Brachial plexus and Axillary nerve injuries
What is the management for Humeral shaft fractures?
Sugar tong splint + Sling/Swathe Ortho w/I 24-48 hrs
MC commonly fractured bone in children /adolescent/ newborn?
Clavicle fracture
Which clavicle fracture requires orthopedic consult?
Proximal 1/3 of involvement of the clavicle
Stiffness/inflammation w Decreased ROM especially with external rotation, you think what disorder?
Tx:

Tx: NSAIDs, PT ROM, IACS injection
Pain or paresthesia’s to the forearm and or Ulnar side of hand: (+) Adson’s
Dx: Tx:

Dx: MRI Tx: PT, Ortho, +/- Surgery
On x-ray you see a displaced anterior fat pad and (+) posterior fat pad sign (hemarthrosis), you think what lesion? Tx:
Supracondylar humeral Fracture (Kid)
Radial Head fracture (Adult)
Tx: Non displaced= Posterior splint
Displaced= ORIF
Median nerve and Brachial Artery injury are consistent with ?
Volkmann Ischemic contracture (Claw-like deformity)
Supracondylar Humeral fractures are MC with what MOI and ages?
FOOSH MC in children 5-10 YOA
Lateral radial pain with inability to fully extend the elbow: (+) posterior fat pad or displaced A. fat pad?
