Lawson's classification of naviculars pertains to which bone?

• A. Navicular bone
• B. Talus
• C. Calcaneus
• D. Cuboid

Answer: (A)

Lawson's classification of naviculars is about the navicular bone in the foot. The navicular is the midfoot tarsal that sits between the talus proximally and the three cuneiforms distally, and Lawson’s system describes variations of that specific bone. So the bone in question is the navicular bone itself. The other bones listed—the talus, calcaneus, and cuboid—are different tarsals and are not described by Lawson’s navicular classification.
