Fractures Flashcards
Impaction is
= compression with axial load
Depression & compression
Avulsion
= tensile loading of fragment & main body of bone
Muscle contraction or passive loading
Greenstick fracture
- Fracture on side of TENSILE loading
- Angular displacement common
Torus fracture
- Impaction fracture on side of compressive loading
Plastic bowing fracture
- Longitudinal compression forces exerted, capacity for elastic recoil exceeded
- Likely a component of all pediatric fractures
Physeal fractures - type 1
Growth plate only
Slipped
Type II
Physis and metaphysis
Above
Type III
Physis and epiphysis
Lower
Type IV
Epiphysis, physis, and metaphysis
Through
Type V
crush injury of physis
Ruined
Type VI
Rang’s: involves perichondral ring or associated periosteum of physis
Type VII to IX ( 7-9) unique how?
Ogdens
do not directly involve physis,
though may disrupt blood supply
Type VII
Osteochondral epiphysis fracture
Type VIII
Metaphysis fracture
Type IX
avulsion of periosteum
