In this article, we present a 47-year-old female patient applying with pain in posteromedial of ankle and trigger toe complaints. There was no predisposing factor such as dance or sports or any radiological sign such as os trigonum. Posterior ankle endoscopy technique was used for evaluation and it was observed that the FHL tendon was triggered. Fibrous thickening around the tendon was released with endoscopic instruments. After release, it was observed that the FHL tendon was not triggered with toe movements. Hallux saltans can be treated by posterior endoscopic methods with an attention to the tibial nerve such as other joint and soft tissue pathologies. To the best of our knowledge, this is the first case report of endoscopic treatment of bilateral HS in an ordinary female patient.
