TERMS

Question 1

secondary ossification center at the end of long bones that fuses to the shaft

appearance and fusion dates act as landmarks for skeletal maturity

Answer 1

epiphysis

Question 2

secondary growth center that lacks an articular surface

usually the site of tendon attachment like feet, shoulder, elbow, tibia

appear more fragmented and sclerotic than true epiphysis

Answer 2

apophysis

Question 3

distal tibia is irregularly shaped

happens at the distal tibia through development

Answer 3

physiologic bridging

Question 4

fracture of the distal tibial physis

Answer 4

tillaux fx

Question 5

distal tibia fuses medial to lateral

appears at 8 yrs in females

looks like pseudofractrues/bridging

Answer 5

kump hump

Question 6

posterior process of calcaneus that develops in cartilage of tuber calcanei

Answer 6

calcaneal apophysis

Question 7

fuses at 11 yrs

usually apophysis fuses about a year after posterosuperior calcaneus fuses

Answer 7

postero-superior calcaneus

Question 8

appear at 6 yrs in girls fusing by age 20

becomes os trigonum if unfused

Answer 8

lateral tubercle of posterior process

Question 9

appear at 9 yrs in females, 11 in males

bipartite tibial sesamoids most common

can by physiologically fragmented, which can mimic a fracture

Answer 9

hallucal sesamoids

Question 10

styloid process appears at 9 yrs in girls same time as sesamoids

Answer 10

5th metatarsal apophysis
