DEX IOT DAY ACTUAL EXAM COMPLETE QUESTIONS AND
CORRECT VERIFIED ANSWERS (DETAILED ANSWERS)|ALREADY
GRADED A+

syndesmosis joint
ANSWER IS - also known as tibiofiibular ligament,
located above the ankle joint, comprised of:
AITFL: anterior inferior talo-fibular ligament
PITFL: strongest ligament
Tibiofibular Interosseous ligament: membrane running vertically between fibula and tibia

talus anchor in atfl

ANSWER IS - 2cm from lateral talar process angled 40-45 degrees to the sagittal plane and parallel with
the longitudinal line of fibula, 4:30 for R, 7:30 for L

fibula anchor in atfl

ANSWER IS - 15mm from distal tip of fibula

tensioning atfl ib

ANSWER IS - neutral with 10-15 degrees plantar flexion

medial mal anchor for deltoid ib

ANSWER IS - medial mal in intercollicular grove w/ 4.75 anchor

talus anchor in deltoid ib

ANSWER IS - deep deltoid, 12.2mm/1cm in talus

sustentaculum tali anchor for deltoid ib

ANSWER IS - superficial deltoid, 8mm anterior

deltoid recon

ANSWER IS - superficial tibiocalcaneal & deep posterior tibiotalar

,ESTUDY



superficial deltoid

ANSWER IS - 4, resists eversion of hindfoot

deep deltoid

ANSWER IS - 2, medial ankle sprain, lateral ankle sprain, ankle fracture, flatfoot

mechanical instability

ANSWER IS - clinical and radiographic evidence that demonstrates excess movement of the talus
within ankle mortise

functional instability

ANSWER IS - subjective complaint of patient

sorain classifications

ANSWER IS - Grade 1: ATFL sprain
Grade 2: ATFL & CFL partial tear
Grade 3: ATFL, CFL, and possibly PTFL

sural & superficial peroneal

ANSWER IS - nerves to watch out for with ATFL IB

syndesmosis mechanism of injury

ANSWER IS - forced external rotation of the foot (specifically talus)

syndesmosis function

ANSWER IS - resists movement of:
coronal translation (side to side/left to right)
rotational
sagital translation (forward or backwards)
ideally syndesmosis resists diastesis but allows normal physiological micro-motion

Aitfl mechanism of injyry

, ESTUDY


ANSWER IS - external rotation -> force of the talus pushing on fibula causes tear/stress

when to use aitfl internal brace

ANSWER IS - Re-assess syndesmotic motion. mild rotational instability

Weber Classifications

ANSWER IS - based on level of fibula fracture compared to ankle/syndesmosis joint & better for
surgical decision making

Weber A

ANSWER IS - below ankle joint (infrasyndesmotic)
Avulsion type injury of distal fibula Foot supinated (inversion) with an adduction deforming force
Stress on atfl & cfl causes bone to break off (similar to medial mal) Usually doesn't involve syndesmotic
injury
medial mal is also often fractured

Weber B

ANSWER IS - at the ankle joint (transyndesmotic)
could include syndesmosis injury
most common
medial mal may be fractured or deltoid ligament may be torn
variable stability
foot inverted with external rotation

Weber C

ANSWER IS - above the ankle joint (suprasyndesmotic)
most likely a syndesmosis injury
distal tibiofibular articulation widened
foot in pronation (eversion), the medial structures are under tension and external rotation force is
applied
almost always syndesmosis
deltoid injury and/or medial mal fracture

Lauge hansen

ANSWER IS - describes position of foot at time of injury & deforming forces
