Musculoskeletal Flashcards
Non-displaced
fragments in alignment
Displaced
fragments not aligned
Angulated
Fragments malaligned at agle
Bayonetted
distal fragment longitudinally overlaps proximal frag (side-by-side)
Distracted
distal and proximal fragments separated by gap
Transverse
frx perpendicular to shaft of bone
Comminuted
more than two fragments
Oblique
angulated
Segmental
comminuted fxr w/ completely separate bone segments fractures (e.g. prox and dist ends of femur have fxrs)
Spiral
multiplanar, complex fxr line
Intra-articular
fxr crosses articular cartilage into joint
ALWAYS needs ortho referral
Torus
incomplete buckle (U) kids
Green Stick
incomplete w/ angular deformity
Impaction
fxr caused by one bone impacting adjacent bone
Compression
impaction fxr in vertebrae, depresses endplates
Depression
impaction in knee from femor condyle hits tibial plateau
Stress (Fatigue)
fxr from repeat cyclical loads, in normal bone
Stress (Insufficiency)
weak bone fxr from load that wouldn’t break healthy bone
Pathologic
weak bone fxr from tumor or disease
