Abstract
Isolated posterior tibial tendon dislocation is a rare condition. Diagnosis can be challenging, especially in the acuteclinical setting. Predisposing factors include shallow posterior tibial tendon groove and tear of theflexor retinacu-lum. We report the case of traumatic subluxation of the posterior tibial tendon, illustrating imagingfindings andsurgical technique. Posterior tibial tendon dislocation was detected using dynamic ultrasound, while magneticresonance was essential for a comprehensive evaluation that included underlying predisposing anatomic abnor-malities and associated pathologic conditions. Conservative treatment is often unsuccessful thus surgical approachwas needed. Under ampliscopic guidance, a bone tunnel was created behind the retromalleolar groove. The poste-rior tibial tendon was located into the new groove and the retinaculum was re-attached and tightened by anchorsand absorbable sutures at the anterior margin of the sulcus. At 12-month follow-up, the patient did not complainany residual pain and he was able to perform normal daily activities without any limitations and with no furthertendon dislocationsFile | Dimensione | Formato | |
