Lower-Lying Flexor Hallucis Longus Is Associated With Advancing to Surgery in Pediatric and Adolescent Os Trigonum Syndrome

Key Points

• The aim is to determine if the position of the flexor hallucis longus muscle belly influences the success of nonoperative treatment in os trigonum syndrome.
• Analyzed the anatomical position of the flexor hallucis longus muscle in patients with os trigonum syndrome.
• Monitored treatment outcomes between nonoperative and surgical management.
• Compared muscle belly positioning with surgical intervention rates.
• Patients with a lower-lying flexor hallucis longus were more likely to require surgery.
• Nonoperative management had higher failure rates associated with specific muscle positions.
• Understanding the muscle anatomy can aid in better treatment planning.
