CCEP Anatomy & Biomechanics of Extremities 2

Question 1

Which ligament is the primary restraint to anterior translation of the tibia on the femur?

Accepted Answer

Anterior cruciate ligament

Answer

The ACL is the primary restraint to anterior tibial translation, providing approximately 85% of the total restraining force.

Question 2

The 'carrying angle' of the elbow is formed between the long axis of the humerus and which bone?

Accepted Answer

Ulna

Answer

The carrying angle is measured between the long axis of the humerus and the long axis of the ulna, averaging 5–10° in males and 10–15° in females.

Question 3

During the stance phase of gait, the subtalar joint undergoes which motion to allow the foot to accommodate uneven terrain?

Accepted Answer

Pronation followed by supination

Answer

At initial contact the subtalar joint pronates to absorb shock, then supinates during mid-to-late stance to create a rigid lever for push-off.

Question 4

The coracohumeral ligament primarily limits which motion of the glenohumeral joint?

Accepted Answer

External rotation and inferior translation

Answer

The coracohumeral ligament spans from the coracoid process to the greater and lesser tubercles and is a key restraint to external rotation and inferior translation of the humerus.

Question 5

Which tarsal bone articulates with all five metatarsal bases?

Accepted Answer

Cuboid

Answer

The cuboid articulates with the 4th and 5th metatarsal bases directly; combined with the three cuneiforms the tarsometatarsal (Lisfranc) joint spans all five metatarsals, but the cuboid is the only tarsal that contacts the lateral two.
