Question 17

Hamate, Capitate, Trapezoid, Trapezium

The arrangement of the distal carpal bones from medial to lateral is Hamate, Capitate, Trapezoid, and Trapezium. This sequence accurately reflects their anatomical positioning in the wrist.

A) Hamate, Capitate, Trapezoid, Trapezium

This option is correct as it lists the distal carpal bones in the proper medial to lateral arrangement. The Hamate is located on the medial side, followed by the Capitate, then the Trapezoid, and finally the Trapezium on the lateral side.

B) Capitate, Trapezium, Hamate, Trapezoid

This option is incorrect because it misplaces the bones. The Capitate should be positioned medial to the Trapezium, and the Hamate should be on the medial side, not mixed with the lateral bones.

C) Trapezoid, Hamate, Capitate, Trapezium

This option is also incorrect as it starts with the Trapezoid, which is one of the more lateral bones. The Hamate should be placed more medially, and the arrangement does not follow the correct medial to lateral order.

D) Trapezium, Trapezoid, Capitate, Hamate

This option is incorrect because it lists the Trapezium first, which is the most lateral bone. The Hamate should be at the medial end of the arrangement, making this sequence inaccurate.

Conclusion

The correct answer, Hamate, Capitate, Trapezoid, Trapezium, accurately reflects the anatomical orientation of the distal carpal bones. All other options fail to maintain the proper order from medial to lateral, highlighting the importance of understanding anatomical positioning in the wrist.
