General Orthopedics Flashcards
What is the end portion of a long bone?
Epiphysis
What is the middle portion of a long bone?
Diaphysis
How do we classify physeal fractures?
Salter Harris types 1-5
Commonly lead to premature closure of the physis
Physeal fractures (Salter Harris fractures)
Fracture of the zone of hypertrophy (directly across the physis)
SH type 1
One of the more common Salter Harris fractures in all species
SH type 2
Salter Harris fracture that involves most of the physis and a small portion of metaphyseal bone
SH type 2
Salter Harris fracture that involves a portion of the epiphysis
SH type 3
Salter Harris fracture that involves the epiphysis and a the metaphysis
SH type 4
Which Salter Harris fracture can you not see on radiographs?
SH type 5
Compression/crush injury to the physis
SH type 5
Causes disruption of physical growth d/t premature closure of the growth plate
SH type 5
What post-operative feature is the key to good prognosis of an articular fracture?
Early return to function
What will happen if an articular fracture is allowed to rest for prolonged periods post-op?
Fibrosis and decr. ROM in joint
Periosteal proliferation in the diaphyses d/t a thoracic mass
Osteopathy
