SECTION 1: ANATOMY AND BIOMECHANICS
Question 1: What three bones fuse together to form the hip bone?
A) Ilium, ischium, and pubis
B) Ilium, sacrum, and coccyx
C) Femur, tibia, and fibula
D) Ischium, sacrum, and pubis
Answer: A
Rationale: The hip bone (os coxae) is formed by the fusion of three bones: the ilium (superior and widest
portion), the ischium (lower, posterior portions), and the pubis (medial anterior portion). These bones fuse
at the acetabulum to form the socket of the hip joint.
Question 2: The strongest bone in the body is the:
A) Tibia
B) Femur
C) Pelvis
D) Sacrum
Answer: B
Rationale: The femur is the strongest and longest bone in the human body, capable of withstanding
significant weight-bearing forces and impacts. Its strength is essential for supporting body weight and
facilitating locomotion.

,Question 3: Which of the following comprises the hip joint?
A) Fibrous joint
B) Synovial, ball and socket joint
C) Cartilaginous joint
D) Pivot joint
Answer: B
Rationale: The hip joint is a synovial, ball and socket joint that allows for a wide range of motion in
multiple planes while maintaining stability. The ball is the femoral head, and the socket is the acetabulum.
Question 4: The hip joint has how many degrees of freedom?
A) 1 degree of freedom
B) 2 degrees of freedom
C) 3 degrees of freedom
D) 6 degrees of freedom
Answer: C
Rationale: The hip joint has 3 degrees of freedom, allowing movement in three planes: sagittal
(flexion/extension), frontal (abduction/adduction), and transverse (internal/external rotation).
Question 5: The normal range for acetabular inclination in the coronal plane is:
A) 10-20 degrees
B) 20-30 degrees
C) 30-50 degrees
D) 50-70 degrees

,Answer: C
Rationale: Acetabular inclination refers to the angle at which the acetabulum faces inferiorly in the
coronal plane. The normal range is 30-50 degrees. This angle is critical for proper hip biomechanics and
stability.
Question 6: The average acetabular anteversion in the sagittal plane is:
A) 5 +/- 3 degrees
B) 10 +/- 5 degrees
C) 17 +/- 6 degrees
D) 25 +/- 8 degrees
Answer: C
Rationale: Acetabular anteversion is the angle at which the acetabulum faces anteriorly in the sagittal
plane. The average is 17 +/- 6 degrees, which helps maintain proper joint congruency and stability.
Question 7: Femoral neck anteversion refers to the angle between:
A) Femoral neck and femoral shaft
B) Femoral head and acetabulum
C) Femoral shaft and tibial shaft
D) Femoral condyles and patella
Answer: A
Rationale: Femoral neck anteversion (transverse plane) is the angle between the femoral neck and the
femoral shaft, indicating the degree of torsion of the femur. The normal average is 10-20 degrees in adults

, Question 8: What does the term "anteversion" mean?
A) Rotated backward, toward the back of the body
B) Rotated forward, toward the front of the body
C) Rotated laterally, away from the midline
D) Rotated medially, toward the midline
Answer: B
Rationale: Anteversion means rotated forward, toward the front of the body. In the context of the hip,
femoral neck anteversion describes the forward angle of the femoral neck relative to the femoral shaft .
Question 9: The strongest bone in the body is the:
A) Femur
B) Tibia
C) Pelvis
D) Sacrum
Answer: A
Rationale: The femur is the strongest and longest bone in the human body. Its robust structure is essential
for supporting the body's weight and withstanding the significant forces generated during activities like
walking, running, and jumping.
Question 10: The closed pack position of the hip is characterized by:
A) Max flexion, abduction, and external rotation
B) Max extension, adduction, and internal rotation
