26
Depression of the humeral head is defined as what and a/w what UE injury?

27
Decreased sensation to the lateral aspect of the shoulder (acute) and decreased deltoid function (chronic) is a/w what UE injury?
Axillary nerve injury/ glenohumeral dislocation
28
What concerning signs on x-ray should warrant referral even if a fx is not evident?
Fat pad sign Sail sign
29
How can you differentiate between subluxation and dislocation?
Subluxation- may spontaneously reduce, can become recurrent Dislocation- clinically deformed, painful, decreased ROM, requires surgical reduction
30
What imaging is ordered for a subluxation or dislocation?
**Plain xrays = diagnostic** CT to eval alignment, fractures, avulsions MRI to eval ligament integrity
31
What is included in the tx for a subluxation/ dislocation?
Immediate reduction Casting vs sling/ early mobilization +/- PT Surgery if complex/ NV involvement
32
Pt presents w/ localized pain, swelling +/- wrist/ elbow pain and hx of direct impact. What should you eval for?
Forearm fx ALWAYS consider 2 fxs (radius + ulna) OR fx + dislocation
33
Pt with forearm fx will display restricted ROM with what movements?
Supination and pronation
34
What imaging should be ordered for suspected forearm fx?
AP/ lateral xray \*if only 1 fx seen, look for another and assess joints\*
35
What should be ruled out w/ "isolated" ulnar shaft fractures and how is it dx?
Ulnar shaft fracture w/ dislocation of radial head (Monteggia fx) Dx w/ xray (include elbow)
36
What is included in the management for a nondisplaced forearm fx?
Splint + refer for casting (6-8 wks) NSAIDs, elevation, sling, ice
37
Pt with nondisplaced forearm fx should refrain from sports activity for how long?
4-6 mos (high risk of re-fx)
38
What is included in the management for a displaced forearm fx?
Emergent reduction ORIF: IM rods
39
What does ORIF stand for?
Open reduction internal fixation
40
What does CRPPF stand for?
Closed reduction percutaneous pin fixation
41
What does DRUJ stand for?

43
What xrays should be ordered for a wrist fx?
AP, lateral, oblique +/- scaphoid
44
What is included in the tx for wrist fx?

46
What is the most common carpal bone fractured in the wrist and how is it dx?
Scaphoid Clinical dx- "anatomic snuffbox" TTP
47
What xrays are ordered for scaphoid fx?
