SCS Anatomy & Biomechanics

Question 1

The rotator cuff is composed of which four muscles?

Accepted Answer

Supraspinatus, infraspinatus, teres minor, subscapularis

Answer

The rotator cuff consists of supraspinatus, infraspinatus, teres minor, and subscapularis, remembered by the SITS acronym.

Question 2

Which ligament primarily prevents anterior tibial translation relative to the femur?

Accepted Answer

Anterior cruciate ligament

Answer

The ACL is the primary restraint against anterior tibial translation and also limits internal tibial rotation.

Question 3

The Q-angle is measured using which anatomical landmarks?

Accepted Answer

ASIS to center of patella to tibial tuberosity

Answer

The Q-angle is formed by lines from the ASIS to the patellar center and from the tibial tuberosity to the patellar center.

Question 4

During normal walking gait, the center of mass follows which movement pattern?

Accepted Answer

A sinusoidal path in both vertical and lateral planes

Answer

The center of mass oscillates both vertically and laterally during walking, tracing a sinusoidal path in each plane.

Question 5

Which structure provides the primary static restraint against inferior glenohumeral translation with the arm at the side?

Accepted Answer

Superior glenohumeral ligament

Answer

The superior glenohumeral ligament (SGHL) is the primary static stabilizer resisting inferior translation of the humeral head when the arm is adducted.
