title: Os trigonum syndrome.
abstract: Os trigonum syndrome refers to a constellation of findings that can result in significant posterior or lateral ankle pain. The diagnosis may be very challenging for the clinician; nonetheless, modern imaging techniques can reliably aid in the diagnosis and in determining the extent of injury. This article explores the anatomy, pathomechanics, imaging findings, and clinical presentation of os trigonum syndrome.
