Lateral Foot Pain in a Recreational Runner.

A 35-year-old male recreational runner with a 9-month history of left lateral foot pain self-referred to physical therapy while awaiting orthopaedic consultation. Before presenting to physical therapy, his primary care physician ordered radiographs and referred him to orthopaedics with a provisional diagnosis of multipartite os peroneum. Following examination, the initial treatment hypothesis was cuboid syndrome, as he met the majority of items in a proposed diagnostic cluster.
