Which dysfunction commonly occurs with cuboid dysfunction?

• A. Navicular dysfunction
• B. Achilles tendinopathy
• C. Fifth metatarsal stress fracture
• D. Posterior tibial tendon dysfunction

Answer: (A)

Cuboid dysfunction disrupts the stability of the lateral column of the foot, which in turn changes how load is transferred through the entire arch. When that lateral component is out of place, the medial column often compensates, and the navicular bone can move abnormally or show altered height during weight-bearing. This pattern—altered navicular position in relation to the arch—is a common finding when cuboid problems are present, so navicular dysfunction frequently accompanies cuboid subluxation.

Achilles tendinopathy, fifth metatarsal stress fracture, and posterior tibial tendon dysfunction are more closely tied to different parts of the hindfoot or medial column mechanics and aren’t as typically linked as a concurrent finding with cuboid dysfunction.
