Which tarsometatarsal joint has the least amount of motion in the sagittal plane?

• A. First tarsometatarsal joint
• B. Second tarsometatarsal joint
• C. Fourth tarsometatarsal joint
• D. Fifth tarsometatarsal joint

Answer: (B)

The second tarsometatarsal joint is characterized by a significant amount of stability due to its structural and functional role in the foot. This joint provides important support for the medial arch and facilitates efficient weight-bearing and propulsion during gait. The second metatarsal often serves as an anchoring point for the surrounding metatarsals, limiting excessive motion. In the sagittal plane, the second tarsometatarsal joint has the least amount of motion compared to the other joints. The first tarsometatarsal joint exhibits a greater range of motion to accommodate the dynamic movements of the hallux during activities like walking and running. Similarly, the fourth and fifth tarsometatarsal joints allow for more mobility to aid in the foot’s adaptation to uneven surfaces and provide lateral stability. Overall, the structural composition and biomechanical role of the second tarsometatarsal joint contribute to its minimal motion in the sagittal plane, which is essential for maintaining proper alignment and function of the foot during various activities.
