25
Q

Clinical features of bicep tendon tear:

A

pop at elbow when tendon ruptures
pain is severe at first, but subsides after 1-2 weeks
swelling at elbow
bruising in elbow and forearm
pain and weakness of elbow flexion and forearm supination

26
Q

Cervical Disc Herniation:

A

linked to a variety of neuropathic problems and often times resulting in severe pain, resulting in decrease quality of life

27
Q

What are neuropathic complicxations?

A

neck and arm pain accompanied by changes in motor, sensory and reflex changes

28
Q

Primary motion of C1 (atlas)

A

flexion and extension

29
Q

Primary motion of C2 (axis)

A

rotation

30
Q

A

pre-transverse VA
cervical Va
suboccipital VA
intracranial VA

31
Q

A

flexion and extension

protraction and retraction

32
Q

Cranial motion in the horizontal plane:

A

axial rotation

33
Q

Cranial motion in the frontal plane:

A

lateral flexion

34
Q

Stable cervical spine injury:

A

compression fracture
traumatic disk herniation
unilateral facet dislocations

35
Q

Unstable cervical spine injury

A

fracture-dislocations

bilateral facet dislocations

36
Q

MOI of cervical spinal injury

A

aging and degeneration
traumatic injury
acute disk injury

37
Q

Signs and symptoms of cervical spine injury

A
ipsilateral pain in the neck
radiating pain down the arm and fingers
numbness or tingling
neck flexion and arm abduction
decreased sensation to pain, touch or vibration
cervical radiculopathy
cervical myelopathy
38
Q

Why is the AC joint susceptible to dislocation?

A

because of the sloped nature of the articulation and the high probability of receiving a large shearing force

39
Q

What is the MOI for AC joint separation?

A

Blunt trauma

Force applied directly over the superolateral border of the shoulder usually during a fall with the humerus adducted

40
Q

What are the primary movements of AC joint?

A

upward and downward rotation

41
Q

What are the secondary movements of the AC joint?

A

external and internal rotation

anterior and posterior tilting

42
Q

What are the signs and symptoms of AC joint separation?

A
pain, regional swelling, and bruising
decreased ROM
Scapular weakness
hypermobile clavicle
elevated clavicle
43
Q

Where is a proximal stress fracture?

A

the greater trochanter, femoral neck or in the femoral head

Most often the greater trochanter

44
Q

What are risk factors for hip fractures?

A
cardiovascular disease
heart failure
smoking
tall stature
stroke 
dementia
45
Q

MOI for stress fractures?

A

overuse
repetitive microtrauma
repetitive high loading which lead to weakened bone trabeculae

46
