The medial malleolar fleck sign (MMFS) is a radiographic indicator of medial ankle instability, conventionally interpreted as an avulsion of the deltoid ligament from its tibial insertion. However, its precise anatomical origin remains unclear, with limited intraoperative confirmation reported in the literature. We present a case of a 51-year-old woman with a left ankle inversion injury, resulting in a Weber B fibular fracture, posterior malleolar fracture, and a cortical fragment consistent with MMFS, accompanied by medial clear space widening.

Pediatric ankle injuries are common; ankle epiphyseal fractures are also common in children. But isolated distal epiphyseal fibular fractures of the distal fibula are clinically rare. We describe one unusual case of an adolescent with a completely displaced Salter-Harris type II distal fibular epiphyseal fracture.

A linear flake of bone at the posterolateral aspect of the distal fibula indicates avulsion of the superior peroneal retinaculum and warrants further investigation by dynamic ultrasound.

Background: This study analyzes position of the peroneal tendons and status of the superior peroneal retinaculum (SPR) whenever a lateral malleolar bony flake fracture occurs.
Methods: Twenty-four patients had a lateral malleolar bony fleck on anteroposterior ankle radiographs, either in isolation or associated with other hindfoot injuries. We studied size of the bony flecks, presence or absence of peroneal tendon dislocation and pathoanatomy on CT scans.
