Posterior Tibial Tendon Dislocation: A Case Report

Abstract Isolated posterior tibial tendon dislocation is a rare condition. Diagnosis can be challenging, especially in the acute clinical setting. Predisposing factors include shallow posterior tibial tendon groove and tear of the flexor retinaculum. We report the case of traumatic subluxation of the posterior tibial tendon, illustrating imaging findings and surgical technique. Posterior tibial tendon dislocation was detected using dynamic ultrasound, while magnetic resonance was essential for a comprehensive evaluation that included underlying predisposing anatomic abnormalities and associated pathologic conditions. Conservative treatment is often unsuccessful thus surgical approach was ne…
