Chapter 92 - Fractures of the Elbow

Question 1

indications for radial head r eplacement

Answer 1

> 3 parts
comminuted

Question 2

outcomes of radial head orif

Answer 2

poor if concomitant elbow instability present

Question 3

what structure is at risk with anterior cortex penetration in olecranon tension band

Answer 3

anterior interosseous nerve

Question 4

when can you perform olecranon fracture fragment excision?

Answer 4

osteoporotic patients, fragments <50% of the olecranon

Question 5

proximal ulnar has a gental dorsal ben averaging 6degrees called what?

Answer 5

the proximal ulna dorsal angle

Question 6

order of fragment fixation in proximal ulna fractures

Answer 6

fix the coronoid then fix the proximal ulna fragment
- the coronoid becomes difficult to visualize once you fix the main proximal fragment of the ulna

Question 7

anteromedial facet of the coronoid is called the ?

Answer 7

sublime tubercle - anterior band of the mcl attaches here

Question 8

what attaches to the tip of the coronoid?

Answer 8

anterior capsule

Question 9

an intact coronoid resists what direction?

Answer 9

posterior elbow displacement

Question 10

anteromedial facet fractures are associted with what?

Answer 10

a varus directed force (results in posteromedial instability often), a LCL avusion, and require a buttress plate for fixation

Question 11

what shoulde rmotion should be avoided in elbow dislocations with LCL repair?

Answer 11

shoulder abduction - gravity places a varus force at the elbow stressing your repair

Question 12

number one complication after ORIF for monteggia

Answer 12

stiffness
