Where is the Lunate?

The lunate is located in the center of the proximal carpal row of the wrist.

Understanding the Lunate's Position

The wrist is composed of several small bones called carpals, which are arranged in two rows: the proximal and the distal.

• Proximal Carpal Row: This row is closer to the forearm and includes the scaphoid, lunate, triquetrum, and pisiform bones.
• Distal Carpal Row: This row is closer to the hand and includes the trapezium, trapezoid, capitate, and hamate bones.

The lunate, as mentioned, resides within the proximal carpal row, and more specifically, in the center of this row.

Lunate's Articulations

• Distal Articulation: The lunate articulates distally with the capitate, which is located in the center of the distal carpal row.
• Radial Articulation: The scaphoid bone articulates with the radial side of the lunate. The scaphoid is unique as it bridges both the proximal and distal rows of the carpals.

Key Points about the Lunate's Location

• The lunate occupies a central position in the proximal carpal row.
• Its position allows it to articulate with bones in both the proximal and distal rows.
