为了评估舟骨梯形 (STT) 关节的解剖变化和退行性变化的分布，对 165 个经过防腐处理的尸体手腕进行了检查。 81%的腕部发现舟骨远端关节面有分界脊，舟骨远端关节面形状分为3种类型。 15% 的手腕发现头状梯形韧带发育不全。从解剖学和放射学角度研究了 STT 关节中梯形-梯形关节面倾斜度（TT 倾斜度）的新骨骼测量方法。 39% 的手腕出现退行性变化。最常见的退变位置是舟状骨远端的尺侧以及 TT 侧梯形的桡侧和中央侧。退行性变化的存在与较高的解剖学和/或放射学 TT 倾斜和/或头状梯形韧带发育不全具有显着相关性。 （J Hand Surg 2000；25A：899-910。美国手外科学会版权所有 (C) 2000。）。
To evaluate anatomic variations and distribution of degenerative changes in the scaphotrapezio-trapezoidal (STT) joint, 165 embalmed cadaver wrists were examined. An interfacet ridge on the distal scaphoid was found in 81% of the wrists and the shape of the distal joint surface of the scaphoid was classified into 3 types. Underdevelopment of the capitate-trapezium ligament was found in 15% of the wrists. A new skeletal measurement for the inclination of the joint surface of the trapezium-trapezoid in the STT joint (TT inclination) was investigated anatomically and radiographically. Degenerative changes were found in 39% of the wrists. The most common location of degenerative changes was on its ulnar aspect on the distal scaphoid and on the radial and central aspect of the trapezoid on the TT side. The presence of degenerative changes had a significant correlation with a higher anatomic and/or radiographic TT inclination and/or underdevelopment of the capitate-trapezium ligament.
