Question 1: A fracture occurring through bone that has been weakened by a pre-existing condition such as cancer or osteoporosis is classified as which type?
- Stress fracture
- Pathologic fracture (Correct answer)
- Avulsion fracture
- Fatigue fracture
Correct answer: Pathologic fracture
A pathologic fracture occurs through diseased or structurally weakened bone and can result from minimal or no trauma.
Question 2: Which fracture type involves a fragment of bone being pulled away at a tendon or ligament attachment site?
- Impacted
- Comminuted
- Avulsion (Correct answer)
- Spiral
Correct answer: Avulsion
An avulsion fracture occurs when a forceful muscle contraction or ligament stress pulls a bone fragment away from its attachment point.
Question 3: The Neer classification system is used to categorize fractures of which bone?
- Proximal humerus (Correct answer)
- Proximal femur
- Distal tibia
- Proximal radius
Correct answer: Proximal humerus
The Neer classification categorizes proximal humerus fractures into two-, three-, or four-part patterns based on displacement of the major bony segments.
Question 4: Which fracture results from repetitive microtrauma and is commonly seen in distance runners and military recruits?
- Pathologic
- Greenstick
- Stress (Correct answer)
- Impacted
Correct answer: Stress
Stress fractures result from cumulative repetitive loading that exceeds the bone's ability to remodel, commonly occurring in the metatarsals, tibia, and femoral neck.
Question 5: In a Salter-Harris Type II physeal fracture, the fracture line passes through which structures?
- Only the physis
- The physis and epiphysis
- The physis and metaphysis (Correct answer)
- Only the epiphysis
Correct answer: The physis and metaphysis
Salter-Harris Type II is the most common physeal fracture, with the fracture line extending through the growth plate (physis) and into the metaphysis.
Question 6: A boxer's fracture most commonly involves a fracture through the neck of which metacarpal?
- First
- Second
- Fourth
- Fifth (Correct answer)
Correct answer: Fifth
A boxer's fracture typically involves the neck of the fifth (small finger) metacarpal, usually resulting from an axial load delivered by a closed-fist punch.
