Question 1

Which type of fracture is characterized by the bone being crushed or compressed, commonly seen in vertebral injuries?

Accepted Answer

Compression fracture

Answer

A compression fracture occurs when bone is crushed under excessive axial force, frequently affecting vertebral bodies in osteoporotic patients.

Question 2

The median nerve passes through which anatomical tunnel at the wrist?

Accepted Answer

Carpal tunnel

Answer

The median nerve travels through the carpal tunnel at the wrist; compression here causes carpal tunnel syndrome.

Question 3

Which anatomical landmark is used to identify the greater trochanter of the femur during assessment?

Accepted Answer

Bony prominence felt on the lateral proximal thigh

Answer

The greater trochanter is palpated as a bony prominence on the lateral aspect of the proximal femur and serves as a landmark for hip assessment.

Question 4

Wolff's Law states that bone will adapt its structure in response to which factor?

Accepted Answer

Mechanical loads placed upon it

Answer

Wolff's Law states that bone remodels and strengthens in response to mechanical stress, which is why weight-bearing exercise improves bone density.

Question 5

Which ligament of the knee prevents anterior displacement of the tibia on the femur?

Accepted Answer

Anterior cruciate ligament

Answer

The anterior cruciate ligament (ACL) resists anterior tibial translation and rotational forces, making it a critical stabilizer of the knee.
