The metacarpophalangeal joint complex represents an articulation not only between the metacarpal and proximal phalanx but in the case of the thumb also between the metacarpal and sesamoids. The collateral ligaments and volar plate contribute significantly to the stability of the metacarpophalangeal joints. Detailed knowledge of the anatomy of the articulations and soft-tissue supports of this complex is necessary for MR imaging detection of subtle injuries to these structures. The role of MR imaging in both acute and chronic trauma to the collateral ligaments and in the often difficult diagnosis of chronic thumb sesamoiditis is presented, with illustrative examples of the normal and pathologic conditions of metacarpophalangeal joints.
掌指关节复合体不仅是掌骨与近节指骨之间的关节，对于拇指而言，还包括掌骨与籽骨之间的关节。侧副韧带和掌板对掌指关节的稳定性有重要作用。要通过磁共振成像（MR）检测这些结构的细微损伤，必须详细了解该复合体关节及软组织支撑结构的解剖学知识。本文介绍了MR成像在侧副韧带急慢性创伤以及慢性拇指籽骨炎（常难以诊断）中的作用，并举例说明了掌指关节的正常和病理状况。
