Musculoskeletal I (fractures) Flashcards
definition of fracture
discontinuity in a bone/cartilage due to mechanical forces
radiological findings may mimic fracture
- vascular/nutrint line
- sesamoid
- accessory ossicles
- apophysis
- growth plates
what is apophysis
separated ossification center
similar to fracture
radiological features of fracture inlude [5]
- discontinuity
- step-off sign
- displacement
- abnormal fat pad
- impaction lines or sclerotic band
radiological describing of any fracture [6]
- (open/closed)
- Position epiphysis/ metaphysis/ shaft (proximal/distal)
- Classification
- location (which bone)
- displacement
- involvement (growth plate/ articular)
classification of fractures
complete
* transverse
* oblique
* spiral
* comminuted
incomplete
* buckle/ torus
* greenstick
types of displacement
LARA
1. length (longitudinal)
2. apposition (translation)
3. rotation
4. angulation
In MSK when we prefer to use MRI?
- when 3d anatomy is complex
- non-displacement fracture
- pathological fracture
when we see moth-eaten appearance?
in multiple myeloma
can you mention common 11 type of fracture
hand
boxer
bennett
scaphoid
forearm
galeazzi
moteggia
colle’s
lower limb
straddle
femoral neck
intertrochanteric
Jones
March
about
colle’s fracture
also called (dinner fork)
fracture in distal radius + (styloid of ulna)
common in elderly
different between
galeazzi & moteggia
galeazzi
* distal
* fracture in radius
* displacement of ulna
Moteggia
* proximal
* fracture in ulna
* displacement of radius
about common fractures of the hand
boxer’s fracture
Bennet fracture
boxer
neck of 5th metacarbal bone
Bennet
base of 1st metacarbal bone
talk about
straddle fracture
- bilateral
- superior and inferior rami of pubis
- urethral injury is common
- common in horseback riders
Jones fracture
in base of 5th metatarsal bone
