Cuboid assumed to become partially subluxed due to excessive traction from peroneus longus as the foot is excessively pronated cuboid not stable as peroneus longus contracts lateral aspect of cuboid pulled dorsally and medial aspect plantarly.
Cuboid may also become subluxed as part of lateral ankle sprain.
In about 4% of all foot injuries in athletes.
Lateral pain on weightbearing – over calcaneocuboid joint and cuboid-metatarsal joints; pain is often referred get a generalised foot discomfort, especially over lateral aspect of foot.
Pressing cuboid upwards can produce pain
Range of movement of cuboid is restricted relative to unaffected foot.
If severe may have shallow depression on dorsum of foot
Has not been documented on x-ray.
Differential diagnosis – sinus tarsi syndrome; stress fracture; peroneal tendonitis; irritation of os peroneum; ankle meniscoid lesion/impingement.
Pain in calcaneocuboid joint has been reported as being common following plantar fascia surgical release.
Manipulation – cuboid pushed upward and laterally from the plantar surface
Ice, strapping, foot orthoses with cuboid notch, footwear with good rearfoot control
