The base of the 5th metatarsal is a common location for lateral foot injuries that occur in athletics. There are three different types of injuries of differing severity that can occur at this junction creating difficulty in assessment, diagnosis, and treatment for the caregiver. An avulsion fracture, Jones fracture, and finally a stress fracture are the three possible bony injuries that can occur in this location. In addition, but uncommonly there can also be accessory or sesamoid bones that can become symptomatic and create additional difficulties in diagnosis and management. The research for this case study was precipitated and conducted based on an injury to the foot of an NCAA Division III male basketball player. The study describes the common signs and symptoms, diagnostic difficulties, treatment options, rehabilitation procedures, and the prognosis for return-to-play.
