Extrinsic ligaments: Radioscaphocapitate ligament, radial collateral ligament, radiolunate ligament, radioscapholunate ligament, ulnolunate ligament, meniscus homologue (radiotriquetral ligament), ulnar collateral ligament; the superficial palmar radiocarpal ligament and the triangular fibrocartilage are not shown. Intrinsic ligaments: scapholunate ligament, lunotriquetral ligament, and palmar intercarpal (deltoid, or V) ligaments. The short palmar intrinsics are not shown.

(B) The dorsal wrist ligaments of the right hand. Extrinsic ligaments: Radiotriquetral, radiolunate, and radioscaphoid fascicles of the dorsal radiocarpal ligament. Intrinsic ligaments: Dorsal intercarpal, trapeziotrapezoid, trapeziocapitate, and capitohamate fascicles of the short intrinsic ligaments. The scaphotrapezium ligament is not shown.
