“…2 It is generally accepted that those on the palmar aspect provide greater restraint to instability. 7 There are 3 strong palmar extrinsic radiocarpal ligaments: the radioscaphocapitate, the long radiolunate, and the short radiolunate ligaments (Fig. 2).…”

“…These three ligaments are considered the main stabilizing elements of the radiocarpal joint (Apergis, ) and in humans they are more developed than the dorsal ligaments (Apergis, ; Mayfield et al, ; Nordin & Frankel, ). Jointly, the three ligaments limit dorsal rotation and translation of the carpus (Katz, Green, Werner, & Loftus, ) and tighten during wrist extension. In addition, the RSC and LRL ligaments are an important stabilizing element of the radial region of the wrist (Cardoso & Szabo, ).…”

Objectives: To identify anatomic differences in the insertion sites of the palmar radiocarpal ligaments in different species of hominoid primates that may be related to their different types of locomotion. Materials and methods:We have used three-dimensional geometric morphometrics (3D GM) to analyze the distal radius ligament insertion sites in 31 Homo sapiens, 25 Pan troglodytes, 31 Gorilla gorilla, and 15 Pongo pygmaeus. We have also dissected the radioscaphocapitate (RSC), long radiolunate (LRL) and short radiolunate (SRL) ligaments in six H. sapiens and five P. troglodytes to obtain quantitative values that were then compared with the results of the 3D GM analysis.Results: H. sapiens had a relatively larger insertion site of the RSC + LRL ligament than the other hominoid primates. P. pygmaeus and P. troglodytes had a relatively large SRL ligament insertion site with a palmar orientation. In G. gorilla, the two ligament insertion sites were relatively smaller and the SRL insertion site had an ulnopalmar orientation.Discussion: The morphological differences observed can be related to the types of locomotion used by the different species and to quantitative data obtained from the dissection of ligaments in H. sapiens and P. troglodytes. 3D GM analysis of ligament insertion sites can help in interpreting the types of locomotion used by extinct hominoid primates through the analysis of preserved fossilized fragments of the distal radius.

“…In particular, the RTL, which is located on the volar side of the wrist and which constrains the volar displacement of the lunate during wrist extension, plays an important role in the maintenance of stability of the lunate. 12,14,15 When the volar carpal ligaments became obviously lax, the dorsal DRC caused a relative DISI deformity. Additionally, the carpal tunnel release and progression of synovitis from the DRUJ worsened the volar carpal instability, which resulted in an extreme DISI deformity, proximal shift of the capitate, and volar dislocation of the lunate.…”

Carpal tunnel syndrome caused by volar dislocation of the lunate in a patient with rheumatoid arthritis

et al. 2006

We report a case of carpal tunnel syndrome caused by volar dislocation of the lunate in a patient with rheumatoid arthritis. A 74-year-old woman complained of numbness in her fingers. Carpal tunnel syndrome was diagnosed, and carpal tunnel release was performed. However, the symptoms recurred. Three-dimensional computed tomography and magnetic resonance imaging revealed volar dislocation of the lunate and synovitis around the distal radioulnar joint, respectively. Resection of the lunate and the Sauvé-Kapandji procedure were effective.
