21
Q

burst fracture of C1 due to compression injury to the head

A

jefferson fracture

22
Q

fracture plane passes all the way through the growth plate, not involving bone
cannot occur if the growth plate is fused reference required
good prognosis

A

TYPE 1 - slipped

23
Q

75% (by far the most common)
fracture passes across most of the growth plate and up through the metaphysis
good prognosis

A

TYPE II - above

24
Q

7-10%
fracture plane passes some distance along the growth plate and down through the epiphysis
poorer prognosis as the proliferative and reserve zones are interrupted

A

TYPE III - lower

25
Q

intra-articular
10%
fracture plane passes directly through the metaphysis, growth plate and down through the epiphysis
poor prognosis as the proliferative and reserve zones are interrupted

A

TYPE IV - through, transverse, together

26
Q

uncommon

A

TYPE V - ruined or rammed
