“…Nagao et al stated that the ulnolunate ligament originates radial to the attachment of the ulnocapitate ligament and ulnotriquetral ligament at the base of the ulnar styloid process and runs parallel to the ulnolunate and the ulnotriquetral ligaments. 4 They also reported that the attachment of the long radiolunate, short radiolunate, radioscapholunate, ulnolunate, and lunotriquetral ligaments on the lunate occupy approximately 49% of all ligament attachments on the lunate. Ulnocapitate ligament: The ulnocapitate ligament originates from the fovea of the ulnar head and proximal 1, third-fourth metacarpal-capitate-hamate intra-articular ligament; 2, third metacarpal ulnar base-fourth metacarpal radial base interosseous ligament; 3, capitate-hamate base interosseous ligament.…”

“…Extrinsic ligaments connect the distal radius and ulna to the carpal bones, and intrinsic ligaments have their origins and insertions within the carpal bones. 2 Nagao et al 4 and Nanno et al 5,6 made computed tomography images of wrists, from which 3-dimensional images of the bones were modeled, and the ligament attachment areas thereupon are listed in Table 1. The presence or absence of each ligament is also noted.…”

“…Several ligaments of the second through fifth CMC joints cannot be seen until more superficial ligaments and tendons are sectioned or completely removed. In addition, there has been little information detailing the location and area of specific ligament attachments on the three-dimensional (3D) surface of the individual MCs and carpal bones (Nagao et al, 2005). Visually demonstrating the attachment sites of the ligaments on 3D images of the bone can help provide a more accurate understanding of the anatomy and location of ligaments.…”

The purpose of this study is to clarify, measure, and show the anatomic locations and areas of specific ligamentous attachments and paths of the second through fifth carpometacarpal (CMC) joints on a three-dimensional (3D) surface model. Ten fresh-frozen cadaver wrists were used to dissect and identify the second through fifth CMC ligaments. Their ligamentous attachments and whole bone surfaces were digitized three-dimensionally and their areas calculated. The attachments of each ligament were represented in a model combining CT surfaces overlaid by a digitized 3D surface, and were also visually demonstrated with a specific color on 3D images of the bones. Nine dorsal and 11 palmar CMC ligaments and one CMC interosseous ligament were identified in the second through fifth CMC joints. An intra-articular ligament between the third metacarpal (MC), the fourth MC, capitate, and hamate was also identified. Five dorsal and five palmar intermetacarpal ligaments and three intermetacarpal interosseous ligaments were also identified in the second through fifth intermetacarpal joints. A previously undescribed palmar intermetacarpal ligament was located between the third, fourth, and fifth MC bases. The anatomic 3D attachment sites of the second through fifth CMC ligaments were visually depicted qualitatively, and their areas quantified. This 3D information will not only afford a better understanding of the anatomy and mechanics of the second through fifth CMC joints, but will also assist in the assessment of radiographic images and treatment of various injuries.

“…The ligament courses obliquely ulnarly toward the lunate, supporting, but separate from, the palmar aspect of the SLIO ligament. 1,10 Between the RSC and the LRL is the interligamentous sulcus, which represents a weak zone in the wrist capsule, dividing to form the space of Poirier in a perilunate dislocation. 1 The LRL ligament inserts into the radial half of the palmar surface of the lunate and triquetrum.…”
