This is an example of what type of abnormal alignment
Rotation (external rotation of distal aspect)
26
This is an example of what kind of fracture
Intra-articular
27
Used to describe Impaction fractures of EXTREMITIES When a harder bone impacts a less dense bone & depresses the surface; common location is the tibial plateau
Depression
28
Used to describe Impaction fractures in SPINE Impaction of bone causes loss of height because of telescopnig trabelua; typically appears as incrased density (linear sclerosis) on radiographs
Compression
29
This is an example of what kind of fracture
Depression
30
This is an example of what kind of fracture
Compression
31
Normal stress on abnormal bone = ___ fracture
Insufficiency
32
Abnormal stress on normal bone = ____ fracture
Fatigue
33
This is an example of a ____ (insufficiency/fatigue) stress fracture
Fatigue
34
This is an example of a ____ (fatigue/insufficiency) stress fracture
Insufficiency
35
When a bone is disrupted at a site of preexisting abnormality = ____ fracture
Pathologic
36
This is an example of a ____ fracture
Pathologic
37
This is an example of what type of fracture
Avulsion
38

46
What is shown in this MRI?
Bone Bruise
47
What are the 3 phases of fracture healing?
Inflammatory Reparative Remodeling
48
First stage of Inflammatory Respose - Hematoma & clot formation; granulation tissue
Cellular
49
Second stage of Inflammatory Response - formation of vascular spindle leads to hyperemia, which leads to osteoclastic activity
Vascular
50
Third stage of Inflammatory Response - callus formation begins, fracture becomes hazy/widens
Primary callus
51
The three stages of the inflammatory phase last about
10 days each
52
This is what phase of healing
53
In the ____ phase, marrow cavity is restored, new bone laid down along lines of stress, unnecessary bone removed
Remodeling
54
This is an example of what phase of healing
55
Vascular injury Fat emboli/thromboembolism Compartment syndrome Neurologic injury These are examples of ____ complications of trauma
Immediate (within hours)
56
This is an example of what complication of trauma
Vascular Injury (Immediate)
57
This is an example of what complication of trauma
Delayed union (intermediate)
58
This is an example of what complication of trauma
Complex Regional Pain Syndrome (Intermediate)
59
This is an example of what complication of trauma
Heterotopic Ossification (Intermediate)
60
Type of delayed complication of trauma that involves formation of joint like structures between fracture fragements w/ nonunion
Pseudoarthrosis
61
Delayed complication of trauma where gracture has not united In 6-9 months
Nonunion
62
Delayed complication where healing of fracture fragments occurs causing mechanical or cosmetic issues
