What is the normal capsular pattern for the midcarpal joint?

• A. Flexion > Extension
• B. Flexion = Extension
• C. Abduction and Adduction limited
• D. Extension > Flexion

Answer: (B)

Movements of a joint are governed by the capsule and surrounding ligaments, and a capsular pattern shows a characteristic, directional limitation when the joint capsule is involved. For the midcarpal joint, the normal pattern is an equal limitation in both directions—flexion and extension are similarly restricted. This means when you assess ROM, you’ll typically see flexion and extension limited to about the same extent, rather than one being markedly more limited than the other. Abduction/adduction aren’t the primary directions described for this pattern, and other patterns would indicate different joints or planes being more affected.
