middle
segment of bone
that has been
displaced

penetrates all cortices

Question 15

Greenstick Fracture

Answer 15

Incomplete fracture or

deformity
Compression fracture

Question 17

Stress Fracture

Answer 17

Stress fracture –
gradually develops
from multiple
repetitions of force

Answer 19

distal fragment
altered from normal
relationship with
proximal fragment by
at least 2mm
Bayonet

Question 20

Angulated fracture

Answer 20

longitudinal axis of
displaced distal bone fragment is angled away
from proximal bone

Question 21

Rotation fracture

Answer 21

rotation of distal bone
along its longitudinal axis from proximal
fragment

Question 22

Subluxation

Answer 22

ess than 100% but greater
than 0% apposition between two bone at the
joint level

Question 23

Dislocation

Answer 23

no contact (0% apposition)
between two bones at the joint level

Avulsion Fracture

Answer 26

Occur at site of
muscle, tendon,
or ligament
attachment; from
abrupt pull, piece
of bone is avulsed
with soft tissue
