typically from a defensive injury.
2. Which bone is involved in a Monteggia fracture?
A. Radius
B. Ulna
C. Humerus

radial head.
3. What is the primary function of a short leg cast?
A. Immobilize the knee
B. Immobilize the ankle and foot
C. Correct femoral fractures
D. Align the hip joint
Answer: B. Immobilize the ankle and foot

displacement?
A. Figure-of-eight bandage
B. Sling immobilization
C. Open reduction and internal fixation (ORIF)
D. Traction
Answer: C. Open reduction and internal fixation (ORIF)
