Cuboid subluxation involves displacement of the cuboid, resulting in pain and problems with push off during dancing or running. Its incidence varies with the population being studied, being apparently highest in ballet dancers. Most cuboid subluxations are plantar and medial, with rare dorsal subluxations. Diagnosis rests on adequate clinical evaluation, and traditional imaging tends to be unhelpful. Ultrasound imaging may offer some insights, although much remains to be learned about this imaging modality in cuboid subluxation. Treatment focuses on conservative measures, including cuboid manipulation, bracing and taping, activity modification, and orthotics. Immobilization may be warranted in cases in which instability is noted, such as after acute traumatic injury. Most athletes and dancers with this disorder return to full participation after successful treatment. Adequate awareness and understanding of this condition will lead to improved diagnosis and outcomes.
