【 摘 要 】

Category:Basic Sciences/Biologics, HindfootIntroduction/Purpose:Sinus Tarsi syndrome is a frequent cause of anterolateral foot pain following injury. Chronic lateral subtalar pain, often referred to as “Sinus Tarsi Syndrome”, is commonly reported to occur following trauma. One hypothetical epidemiological predisposing factor for sinus tarsi syndrome is flatfoot deformity with valgus hind foot alignment. Common conservative treatment includes medial heel posting to attempt to widen the sinus tarsi space and alleviate synovitic pain. Although treatment with operative intervention has been reported, no data exists to evaluate if hindfoot realignment functionally opens the sinus tarsi volume.Methods:Weight-bearing Computed Tomography (CT) scans were obtained in 5 healthy volunteers standing at rest on slanted platforms, 25 degree valgus and 25 degree varus. The volume of the sinus tarsi was measured on each scan. Cross sectional area of the sinus tarsi was measured in 3.6 mm slices from the most lateral fully...
