rearfoot Flashcards
hindfoot position for fusion
2-5 deg valgus with calcaneal bissection to tibia, and 5-10 mm lateral to mid diaphyseal to tibia; 10- 15 deg externally rotated in thigh/foot axis
for a triple, which joint requires longest time for revascularization
TN fusion
most common cause of haglunds deformity
high calcaneal inclination angle
dowel-graft arthrodesis technique aka
trephine arthrodesis technique
contraindications for trephine arthrodesis
If realignment or shortening is desired, it is recommended that traditional joint resection beused for fusion and repositioning
sliding the calcaneus anterior to the talus vs posterior to the talus will cause what changes to forefoot/rearfoot position
Sliding the calcaneus anteriorly on the talus results in dorsiflexion of the forefoot on the rearfoot (decreasing arch height)
Sliding the calcaneus posteriorly on the talus results in plantarflexion of the forefoot on the rearfoot (increasing arch height)
main blood supply to body of talus
artery of tarsal canal and artery of sinus tarsi
deltoid arterial branches off what
artery of tarsal cancal
rupture of deltoid ligament can cause what type of compromise
can cause vascular compromise to talar body because a branch of the artery tarsal canal runs through the deltoid ligament to supply medial aspect of talar body
Artery of tarsal canal branches off which artery
posterior tibial A
Artery of sinus tarsi branches off which artery
perforating B of peroneal A
which artery supplies head and neck of talus
dorsalis pedis
What is the Total angle of Ruch
Total angle of Ruch = Fowler & Philip angle +calcaneal inclination angle. Greater than 90* indicates a haglunds deformity.
most common cause for haglunds deformity
high calcaneal inclination angle (therefore, commonly seen with cavovarus foot type)
Heel pad triad
plantar fasciitis
PTTD
tarsal tunnel syndrome
