Palmar plates are being used as a source of graft in radial or ulnar collateral ligament reconstruction, pulley reconstruction, and volar plate arthroplasty. The purpose of this study is to determine morphometric and major histological differences of palmar plates in metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints among fingers, and supply sufficient data which would be useful in reconstruction procedures. Ninety-six MCP and 96 PIP palmar plates of 12 well-preserved formalin-fixed cadavers were measured focusing on their length, width, central thickness, and lateral thickness and statistically analyzed using ANOVA. Randomized three male and three female cadavers' specimens were examined histologically after staining with Masson's trichrome. For central thickness of the PIP joint level, there was significant difference among fingers, caused by the middle and little fingers. For lateral thickness of the PIP joint level, there was significant difference which was originated from little fingers. MCP palmar plates were significantly thicker than PIP joint levels for most of the fingers. There were thicker and denser collagen bands in MCP than PIP palmar plates. The relation of size-related parameters was not close with the thickness parameters. The predicted sizes and thicknesses of palmar plates vary according to fingers. The data collected for each finger in this study should be used as a guide in reconstructive procedures that use palmar plates as source of graft.
掌板正被用作桡侧或尺侧副韧带重建、滑车重建和掌板关节成形术中的移植物来源。本研究的目的是确定手指间掌指（MCP）关节和近端指间（PIP）关节掌板的形态测量和主要组织学差异，并提供在重建手术中有用的充分数据。对12具保存完好的福尔马林固定尸体的96个MCP掌板和96个PIP掌板进行测量，重点关注其长度、宽度、中央厚度和外侧厚度，并使用方差分析进行统计分析。对随机选取的三具男性和三具女性尸体的标本用马松三色染色后进行组织学检查。对于PIP关节水平的中央厚度，手指间存在显著差异，由中指和小指导致。对于PIP关节水平的外侧厚度，存在显著差异，该差异源于小指。大多数手指的MCP掌板比PIP关节水平的掌板厚得多。MCP掌板中的胶原带比PIP掌板中的更厚且更密集。尺寸相关参数与厚度参数的关系不紧密。掌板的预测尺寸和厚度因手指而异。本研究中为每个手指收集的数据应用作使用掌板作为移植物来源的重建手术的指导。
