Musculoskeletal Flashcards
How do you rank muscle strength?
0 - none, 1 - flicker, 2 - eliminate gravity, 3 - with gravity, 4 - against resistance, 5 - full strength
Considerations for MRI imaging
NO metal, very expensive
Considerations for CT scan
Contrast dye can be nephrotoxic
What does DEXA scan for?
Bone mineral density
What is an arthroplasty?
Surgical reconstruction or replacement of joint
What does rheumatoid factor tell us?
Assess autoantibodies, assess for connective tissue disease
What does ESR tell us?
Non-specific measure for inflammation
When is uric acid high?
Gout
When is CRP increased?
Inflammation, infection, malignancy
First step of fracture healing
Hematoma (first 72 hours)
2nd step of fracture healing
Granulation tissue (3-14 days)
3rd step of fracture healing
Callus formation (appears on x ray at end of week 2) - network of bone forms
4th step of fracture healing
Ossification (3 weeks - 6 months) and cast can be removed
5th step of fracture healing
Consolidation - appears repaired on x - ray
6th step of fracture healing
Remodeling - union is complete, exercise is beneficial
Realignment of bone fragments
Reduction
Maintain alignment
Immobilization
Use of “hardware” to surgically fix the fracture
Internal fixation
Used to stabilize during healing, takes place of casting or traction
External fixation
