BLOOD SUPPLY OF TALUS

BLOOD SUPPLY OF TALUS

• Head and Neck regions – rich supply of Superior neck vessels – br of Dorsalis pedis and Artery of sinus tarsi – rare chances of avascular necrosis
• Artery of tarsal canal – branches off the posterior tibial artery – approximately 1cm proximal to division into medial and lateral plantar arteries – most consistent major supply to body of talus – in tarsal canal gives 6 direct vessels to body of talus
• Deltoid artery – br of the artery of tarsal canal – medial ¼ to ½ of body- II major supply to body
• Artery of sinus tarsi – maximum variability in size and origin – lateral 1/8 to ¼ of talar body - but has more potential to supply blood if needed - formed from perforating peroneal, dorsalis pedis or an anastomosis of both – it anastomosis with A. of tarsal canal
• Posterior tubercle – direct branches of posterior tibial
