Brachioradialis

Question 5

Answer 5

Between 80° and 100°

Question 6

Elbow flexor that produces the greatest force

Answer 6

Brachialis

Question 7

When the shoulder simultaneously flexes and adducts

Question 8

Acute phase elbow tendinopathy

Answer 8

• ice

• gentle AROM
• phonophoresis
• relative active rest

Question 9

myositis ossificans

Answer 9

• Formation of bone in atypical locations in the body
• Occurs 40% of time following elbow Fx, but can also occur in TBi, SCI, and burns

Question 10

LCL sprain presentation

Question 11

lateral epi interventions

Question 12

lateral epi special test

Question 13

Medial (ulnar) collateral ligament

Answer 13

• medial support against valgus stresses
• limits end range elbow extension
• anterior fibers are stiffest, strongest, and primary restraint against valgus force
• throwing and golfing put stress on MCL

Question 14

lateral (radial) collateral ligament

Answer 14

• Essential stabilizer of the elbow
• Annular ligament keeps radial head in contact with ulna
• Stability for lateral elbow against varus and supination forces
• Prevents posterior translation of radial head
