Rare Presentation of Flexor Hallucis Longus Tendinopathy, Idiopathic Hallux Saltans

Video Transcription

Video Summary

The video discusses a case report on idiopathic haluxaltans, an uncommon condition that involves the entrapment of the flexor luteus longus (FHL) tendon in the talus. The main cause is thickening of the tendon before it enters its sheath, often seen in athletes who perform excessive plantar flexion movements. The typical locations of the condition are in the FHL sheath, the fibrosus tunnel below the sustentaculum talus, or at the MTP joint. Although the cause is unknown, it may be related to various space-occupying factors. Symptoms include a snapping sensation during active extension of the hallux. The patient in this case had no history of trauma but experienced painless snapping. Conservative treatments were initially attempted but ultimately, surgical intervention was necessary. The fibro-osseous tunnel was partially resected, resulting in successful resolution of symptoms. Arthroscopy was chosen over open release for better visualization and reduced soft tissue damage. This case highlights the effectiveness of surgical treatment for idiopathic haluxaltans.
