“…This is consistent with the in vitro studies of Moritomo et al (2000a) and Cyriax (1926) that report that the trapezoid and trapezium rotate by equal amounts. Cyriax dissected 20 arms and found that the difference in trapezoid and trapezium rotation was 1% of wrist motion (Cyriax, 1926).…”

“…Additionally, this study aimed to determine if the in vivo motion observed was consistent with the reported in vitro motion. According to previous in vitro results reported by Moritomo et al the trapezoid and trapezium move together as a unit along a single path of rotation during all directions of wrist motion (Moritomo et al, 2000a). We found that the in vivo STT motion was in general consistent with that reported in vitro, but that this over-simplified the STT motion.…”

“…It has been suggested that this single path of motion lies in an ulnar-flexion to radial-extension direction parallel to the trapezoid and trapezium articular surface, and that an anatomical feature, the interfacet ridge, further defines this border and articulation path (Kauer, 1986;Moritomo et al, 2000b). Additionally, a recent study proposed that the single axis of rotation, about which the trapezoid and trapezium rotate in all directions of wrist motion, passes through the origin of the scapho-trapezium ligament on the scaphoid (Moritomo et al, 2000a). Though simple and elegant, this theory invites the question of why both the trapezoid and trapezium exist as distinct bones separated by an articulating surface.…”

Background The thumb carpometacarpal (CMC) joint is often affected by osteoarthritis-a mechanically mediated disease. Pathomechanics of the CMC joint, however, are not thoroughly understood due to a paucity of in vivo data. Questions/purposes We documented normal, in vivo CMC joint kinematics during isometric functional tasks. We hypothesized there would be motion of the CMC joint during these tasks and that this motion would differ with sex and age group. We also sought to determine whether the rotations at the CMC joint were coupled and whether the trapezium moved with respect to the third metacarpal. Methods Forty-six asymptomatic subjects were CT-scanned in a neutral position and during three functional tasks (key pinch, jar grasp, jar twist), in an unloaded and a loaded position. Kinematics of the first metacarpal, third metacarpal, and the trapezium were then computed. Results Significant motion was identified in the CMC joint during all tasks. Sex did not have an effect on CMC joint kinematics. Motion patterns differed with age group, but these differences were not systematic across the tasks. Rotation at the CMC joint was generally coupled and posture of the trapezium relative to the third metacarpal changed significantly with thumb position. Conclusions The healthy CMC joint is relatively stable during key pinch, jar grasp, and jar twist tasks, despite sex and age group. Clinical Relevance Our findings indicate that directionally coupled motion patterns in the CMC joint, which lead to a specific loading profile, are similar in men and women. These patterns, in addition to other, nonkinematic influences, especially in the female population, may contribute to the pathomechanics of the osteoarthritic joint.

Background The dorsal capsuloligamentous scapholunate septum (DCSS) is a confluence of the dorsal capsule, the dorsal intercarpal ligament (DIC), and the scapholunate interosseous ligament (SLIOL). It appears to play a role in the stability of the scapholunate articulation. The purpose of this study was to describe the anatomical basis for this structure and to investigate its role in scapholunate instability through sectioning of this structure followed by an arthroscopic and fluoroscopic analysis. Material and Methods In the anatomical part of the study we dissected 3 fresh cadaver wrists to examine the anatomy of the DCSS. In the arthroscopic part of the study we assessed the EWAS grade of SL instability before and after sectioning the DCSS and measured the scapholunate and radiolunate angles fluoroscopically. Results Sectioning the DCSS increased the EWAS grade of SL instability but did not affect the scapholunate gap, the scapholunate angle or radiolunate angle. Conclusion We have demonstrated that there is a distinct structure that is separate from the dorsal capsule, which we have labeled the Dorsal Capsuloligamentous Scapholunate Septum. We believe that the DCSS is a previously unreported secondary stabilizer of the SL joint which may have therapeutic and prognostic implications.
