LIGAMENTS

Question 1

weakest ligament, first to yield to forces that create an external rotation of the fibula

imaging-oblique nature leads to false positive rupture DX

intraarticular -20%

Answer 1

anterior tibiofibular ligament

Question 2

strongest part of the distal syndesmosis

stress results more often in a posterior malleolus avulsion fx than in a rupture of the ligament

Answer 2

posterior tibiofibular ligament

Question 3

fibrocartilage reinforcement of the posterior capsule of the ankle joint

rupture can be the cause of posterior impingement syndrome

Answer 3

transverse tibiofibulare ligament

Question 4

used for mechanics

fxns as a buffer, neutralizing forces during for instance the heel strike phase in walking but also has the fxn in stabilization

Answer 4

interosseous ligament

Question 5

transitional and appears to be a continuous transition between the interosseous tibiofibular ligament and the ATIFL and PTIFL

Answer 5

interosseous membrane ligament

Question 6

this contributes to syndesmostic stability

acting as a restraint against lateral shift of the talus

Answer 6

deep portion of the deltoid ligament
