The purpose of this study was to analyze the palmar plate complex at the proximal interphalangeal joint using a three-dimensional (3D) technique, which makes it easier to understand the dimensions of structures and their relationship to the adjacent components. This method allows individual elements to be removed virtually, facilitating clearer observation of each component. Sixteen cadaveric specimens were dissected and reconstructed in a 3D virtual environment. The palmar plate is made up of a distal, fibrous portion and a proximal, membranous portion, which anchors distally on the base of the middle phalanx and is continuous with the bilateral check-rein ligaments proximally. The accessory collateral ligaments and the A3 pulley suspend the palmar plate laterally.
本研究的目的是使用三维（3D）技术分析近端指间关节处的掌板复合体，这使得更容易理解结构的尺寸及其与相邻组件的关系。该方法允许虚拟移除各个元素，便于更清晰地观察每个组件。对16个尸体标本进行了解剖，并在3D虚拟环境中进行了重建。掌板由远端的纤维部分和近端的膜性部分组成，其在远端锚定在中节指骨的基部，并在近端与双侧止动韧带连续。副侧副韧带和A3滑车在侧面悬吊掌板。
