Isolated cuneiform fractures rarely occur, but must be considered in the differential diagnosis for midfoot injuries. Along with other nondisplaced, nondislocated midfoot injuries, these fractures are commonly missed or delayed in diagnosis. A review of the literature reveals only three other reported cases of isolated medial cuneiform fractures. Because of the difficulties with finding nondisplaced, nondislocated cuneiform fractures on plain film, further studies should be considered. Other medial cuneiform fractures found in the literature were nonisolated. This report describes a case of isolated medial cuneiform fracture in a 26-year-old Special Forces soldier that resulted in a significant delay of diagnosis.
