The purpose of this study was to identify the structural characteristics of the palmar carpal ligaments. The palmar
carpal ligaments of the thirty-two wrist of Korean adults were dissected and observed with the sugical microscope and
then measured the sized of the ligaments.
Palmar radicarpal ligaments were composed of the five ligaments. The radiotriquetral ligament was apperaed at
43.8%. The attaching types of radiocapitate ligament to radius were classified to thress types. The first type is that the
radiocapitate ligament is attached to radius not overlapped with medially situated ligaments, the second type is
overlapped with medially situated ligaments partially, and third type is superficially situated to ulnotriquetral ligament,
the second type is deeply situated and third type is intermingled with ulnotriquetral lignment. The radiolunate ligament
was the thickest than other ligaments.
The palmar ulnocarpal ligaments were composed of the five ligaments. The ulnocapitate ligament was appeared at
59.4%. The ulnocapitiate ligament was strong ligament in the length, the thickness, and the width, The palmar
ulnocarpal ligaments were thin in compare with the palmar radiocarpal ligaments. Ulnoradiate and ulnopisiform
ligament were not prominent, but these two ligaments were important in triangular fibrocartilage complex that was
contributed stability to distal radioulnar jonint.
The distance from styoid process of radius of palmar radiocarpal ligments was shorts in radiocapitate ligament, and
long in radioscapholunate ligament.
