采用三维刚体弹簧模型（3D-RBSM）分析腕关节的受力分布。在中立位时，48%的力通过桡舟窝传递，40%通过桡月窝传递，12%通过三角纤维软骨复合体传递。在功能位时，腕关节、血管略微伸展，导致通过月骨的力显著增加（53%）。月骨似乎比以前报道的承受更多的负荷。
A three-dimensional rigid body spring model (3D-RBSM) was used to analyse force distribution through the wrist joint. In the neutral position, 48% of the force was transmitted through the radioscaphoid fossa, 40% through the radiolunate fossa, and 12% through the triangular fibrocartilage complex, In the functional position, the wrist joint,vas slightly extended, resulting in significantly increased force through the lunate (53%). The lunate appears to bear more load than has been reported previously.
