Complications following tibial intramedullary nailing include anterior knee pain, malunion, nonunion, and symptomatic/prominent interlocking screws. We report a case of a posterior tibial tendon tear caused by placement of a distal interlocking screw which was detected via dynamic ultrasound. This is a rare and possibly underreported complication which could be the cause of persistent medial sided ankle pain following locked tibial nail placement.
