Which joints exist between wedged-in foot bones?

• A. Intercarpal joints
• B. Intercuneiform joints
• C. Tarsometatarsal joints
• D. Interphalangeal joints

Answer: (B)

Joints between the wedged-in foot bones are the intercuneiform joints. The three cuneiform bones (medial, intermediate, and lateral) sit wedged between the navicular bone on top and the bases of the first three metatarsals below, forming part of the foot’s transverse arch. The intercuneiform joints connect these cuneiforms to each other (medial with intermediate, and intermediate with lateral) and allow a small amount of gliding movement to accommodate the arch’s shape. The other options describe joints in different areas or between different bones: intercarpal joints are in the wrist, tarsometatarsal joints are between tarsals and metatarsals, and interphalangeal joints are between toe phalanges.
