[Complete Rupture of the Extensor Hallucis Longus Tendon with Accessory Slip Mimicking a Partial Rupture: A Case Report].

Abstract

The accessory tendon of the extensor hallucis longus is a common type of extensor hallucis longus variation. This is a case of a 38-year-old female patient who initially considered conservative treatment for a suspected partial rupture, but finally underwent surgery after being diagnosed with a complete rupture of the main tendon and accessory tendon medial to the main tendon on MRI scan.
