Question

Accepted Answer

### Question 6
# Brief Explanations:
A displaced fracture occurs when the broken bone fragments are out of their normal alignment, meaning the ends of the broken bone are separated or shifted from their original position. A non - displaced fracture (also called a stable fracture) is when the broken bone fragments remain in their normal alignment, with the bone still having its basic structural integrity in terms of the position of the fragments.
# Answer:
- Displaced fracture: Broken bone fragments are out of normal alignment.
- Non - displaced fracture: Broken bone fragments remain in normal alignment.

### Question 7
# Brief Explanations:
A closed (simple) fracture is a break in the bone where the skin remains intact, so the broken bone does not penetrate the skin. An open (compound) fracture is a fracture in which the broken bone breaks through the skin, which also means there is a risk of infection due to the exposure of the bone to the external environment.
# Answer:
- Closed/simple fracture: Bone breaks, skin remains intact.
- Open/compound fracture: Bone breaks through the skin.

### Question 8
# Brief Explanations:
When a man's leg is crushed between two cars, this is a high - impact, compressive force injury. The most likely type of fracture here is a comminuted fracture (where the bone is broken into three or more fragments) or a compound (open) fracture (since the crushing force may also break the skin) or a depressed fracture (involving compression of the bone). Another possible type is a greenstick fracture in children, but for an adult male, comminuted or compound fractures are more likely due to the severe crushing force.
# Answer:
Comminuted fracture (or compound fracture) is most likely.

### Question 9
# Brief Explanations:
A weightlifter trying to deadlift 600 lbs and then having hamstring pain is more likely to have a muscle strain rather than a fracture. However, if we consider a possible fracture, a stress fracture could occur. Stress fractures are small cracks in the bone that result from repetitive stress or overloading of the bone. In this case, the sudden and extreme load from the deadlift attempt could cause a stress fracture in the femur (thigh bone) or other bones related to the hamstring attachment. But muscle strain is more common here. If we assume a fracture, stress fracture is a candidate.
# Answer:
Stress fracture (or muscle strain, but if fracture, stress fracture) is likely.

### Question 10
# Brief Explanations:
When a woman gets her foot caught in a gopher hole and twists during a fall, this is a rotational and torsional force applied to the foot and ankle. The most likely fractures are ankle fractures (such as a bimalleolar fracture, which involves both the medial and lateral malleoli of the ankle) or a metatarsal fracture. Another possibility is a sprain, but for fracture, ankle or metatarsal fractures are common in such twisting injuries.
# Answer:
Ankle fracture (or metatarsal fracture) is most likely.
