An anatomic and biomechanical study of the ligamentous stabilizers of the scaphotrapezial trapezoidal joint was performed in 25 fresh cadaver specimens. A consistent scaphotrapezial ligament complex consisting of four entities was identified. This complex is comprised of a stout scaphotrapezial ligament on the radial and palmar aspects of the scaphotrapezial joint, weak palmar and dorsal capsules, and a scaphocapitate capsular ligament. A biomechanical study subsequently found that these structures were directly related to resisting diastasis of the scaphotrapezial trapezoidal joint. This information is helpful in understanding scaphoid tuberosity fractures, scaphotrapezial instability and arthrosis, scaphoid dislocations, and perhaps scapholunate disassociations.
对25个新鲜尸体标本进行了舟大多角小多角关节韧带稳定结构的解剖学和生物力学研究。确定了一个由四个部分组成的一致的舟大多角韧带复合体。该复合体由舟大多角关节桡侧和掌侧的一条粗壮的舟大多角韧带、薄弱的掌侧和背侧关节囊以及一条舟头关节囊韧带组成。随后的生物力学研究发现，这些结构与抵抗舟大多角小多角关节分离直接相关。这一信息有助于理解舟骨粗隆骨折、舟大多角关节不稳定和关节炎、舟骨脱位，以及可能的舟月分离。
