: Study Group 61% is riding the struggle bus of the sustentaculum tali, we do not understand the difference between the anterior, superficial, and superior attachments of the sustentaculum tali, we looked at the short answer answers from the 2011 back test but just got more confused. We are clear as to its function to redirect force of flexor hallucis longus but how everything else is arranged around it is very vague in the dissector. Below are our guesses at these true/false.
: : 19. Immediately superior to the sustentaculum tali is the tendon of flexor hallucis longus.
: TRUE
False, see subsequent post
: : 20. Immediately medial (superficial) to the sustentaculum tali is the posterior tibial artery/vein and the tibial nerve.
: TRUE
Agreed.
: : 21. Immediately superior to the sustentaculum tali is the tendon of flexor digitorum longus.
: TRUE
Agreed.
: : 22. Attaching to the anterior surface of the sustentaculum tali is the plantar calcaneonavicular (spring) ligament.
: FALSE, attaching to the POSTERIOR surface of the sustentaculum tali is the spring ligament OR attaching to the anterior surface of the sustentaculum tali is the TALOCALCANEAL LIGAMENT of the deltoid ligament.
Kind of agree but the spring ligament attaches along the most anterior extent of the sustentaculum tali.
: : 23. Attaching to the superior surface of the sustentaculum tali is the tibiocalcanial part of the deltoid ligament.
: FALSE, attaching to the superior surface of the sustentaculum tali is the FLEXOR RETINACULUM??
Perhaps. but also the deltoid ligament.
: Thanks, any clarification we can get would be greatly appreciated!!!
Go team!
