Blood Supply to Talus

Discussion

• body of talus is furnished w/ blood vessels from inferior talar surface in sinus tarsi and from talar neck;
• non displaced fractures of talar neck disrupt intraosseous branches of tarsal sinus and tarsal canal, but major vascular sling remains intact;
• w/ displaced fractures of talar neck, branches from dorsalis pedis artery to talar neck, artery to tarsal canal & artery to tarsal sinus (major arterial supply to talus) are ruptured;
• dorsalis pedis artery:
• most blood supplied to the head and neck of the talus arises from the dorsalis pedis artery;
• anastomosis within sinus tarsi & tarsal canal form major blood supply to the talar head;

artery of the sinus tarsi

• the sinus tarsi and sinus canal anastomosis lies beneath the talar neck;
• peroneal artery
• from peroneal artery comes branches to posterior process & branch to form artery of sinus tarsi;
• dorsalis pedis artery
• supplies branches to dorsal talar neck & branch to form artery of sinus tarsi;

artery of sinus canal

• branch of posterior tibial forms anastomotic sling inferior to talus from which branches arise to enter talar neck;
• deltoid branches usually arise from the artery of the tarsal canal & supply the medial third of the body;
• main artery supplying blood to the body of the talus is the artery of the tarsal canal

• The extra-osseous and intra-ossoeus blood supply of the talus.
• Blood supply of the talus.
• The arterial anatomy of the talus.
