“…On the palmar side of the styloid process and the palmar edge of the scaphoid fossa, there is an insertion site common to the radioscaphocapitate (RSC) and long radiolunate (LRL) ligaments, while at the palmar edge of the lunate fossa, there is an insertion site for the short radiolunate ligament (SRL) (Apergis, ). The RSC ligament is inserted proximally on the palmar side of the styloid process of the radius and distally on the scaphoid and the capitate bone (Buijze, Dvinskikh, Strackee, Streekstra, & Blankevoort, ; Buijze, Lozano‐Calderon, Strackee, Blankevoort, & Jupiter, ); the LRL ligament runs between the palmar edge of the scaphoid fossa of the radius and the lunate (Berger, ); the SRL ligament spans the palmar edge of the lunate fossa of the radius and the lunate. 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, ).…”

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.

“…The anatomical features of the scapholunate complex play an important role in the biomechanics of this joint. The dorsal part of the SLIL is described as being thick, tight and short, whereas the palmar part of the SLIL is thin, longer and slacker (Buijze et al., 2011; Kauer, 1986). Wrist extension probably causes tension in the palmar part of the SLIL, and wrist flexion could produce tension in the dorsal part of the SLIL combined with closing of the scapholunate joint gap by traction on the palmar SLIL (Kauer, 1974, 1986).…”

Additional fixation of the palmar scapholunate interosseous ligament has been advocated to improve the long-term results of dorsal scapholunate interosseous ligament reconstruction. To investigate the validity of this approach, we determined normal scapholunate motion patterns and calculated the location of the scapholunate rotation axis. We hypothesized that the optimal location of the scapholunate interosseous ligament insertion could be determined from the scapholunate rotation axis. Four-dimensional computerized tomography was used to study the wrist motion in 21 healthy participants. During flexion–extension motions, the scaphoid rotates 38° (SD 0.6°) relative to the lunate; the rotation axis intersects the dorsal ridge of the proximal pole of the scaphoid and the dorsal ridge of the lunate. Minimal scapholunate motion is present during radioulnar deviation. Since the scapholunate rotation axis runs through the dorsal proximal pole of the scaphoid, this is probably the optimal location for attaching the scapholunate ligament during reconstructive surgery.

“…These earlier studies of the anatomy of the scaphoid analysed specimens by manually measuring the morphology with a caliper or two-dimensional slices of CT scans [8,28,29] which can be imprecise and disregards the complex and variable three-dimensional anatomy. Only a few studies besides ours have used 3D reconstruction of computed tomography [15,27,30,31]. Van de Giessen et al [32] calculated a statistical shape model of the scaphoid using a series of 50 CT scans with an average isotropic voxel of 0.3 mm.…”

Background A detailed understanding of scaphoid anatomy helps anatomic fracture reduction, and optimal screw position. Therefore, we analysed (1) the size and shape variations of the cartilage and osseous surface, (2) the distribution of volumetric bone mineral density (vBMD) and (3) if the vBMD values differ between a peripheral and a central screw pathway? Methods Forty-three fresh frozen hand specimens (17 females, 26 males) were analysed with high-resolution peripheral quantitative computed tomography (HR-pQCT) and dissected to compute a 3D-statistical osseous and cartilage surface model and a 3D-averaged vBMD model of the scaphoid. 3D patterns were analysed using principal component analysis (PCA). vBMD was analysed via averaging HR-pQCT grey values and virtual bone probing along a central and peripheral pathway. Results (1) PCA displayed most notable variation in length ranging from 1.7 cm (− 2SD) to 2.6 cm (mean) and 3.7 cm (+ 2SD) associated with differences of the width and configuration of the dorsal surface (curved and narrow (4 mm) to a wider width (9 mm)). (2) High vBMD was located in the peripheral zone. Lowest vBMD was observed in the centre and waist. (3) Virtual probing along a peripheral pathway near to the cartilage surfaces for the capitate and lunate allowed the center region to be bypassed, resulting in increased vBMD compared to a central pathway. Conclusion High anatomical variations regarding the osseous and cartilage surfaces were associated with three distinct concentrically arranged zones with notable different vBMD. The complex scaphoid anatomy with its waist might alter the strategy of fracture fixation, education and research.
