This study evaluated the correlative use of MRI methods and gross anatomy to monitor tendon displacement in the central region of the palm at rest and during flexion and extension of the metacarpophalangeal and interphalangeal joints with respect to the corresponding neurovascular bundles (NVBs). In all of the samples the neutral and extended positions showed the NVB to be palmar with respect to the flexor tendons, while during flexion tendon displacement caused the NVB to be dorsal to both the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) tendons. T1-weighted MR images correlated with gross anatomical slides demonstrated that significant changes occur in the relative positions of the flexor tendons and associated NVBs of the palm upon flexion and extension.
本研究评估了磁共振成像（MRI）方法与大体解剖学的相关应用，以监测手掌中央区域在静止状态以及掌指关节和指间关节屈伸过程中，相对于相应神经血管束（NVBs）的肌腱移位情况。在所有样本中，中立位和伸展位时，神经血管束相对于屈肌腱位于掌侧，而在屈曲过程中，肌腱移位导致神经血管束位于指浅屈肌（FDS）和指深屈肌（FDP）肌腱的背侧。T1加权磁共振图像与大体解剖切片的对比显示，手掌屈肌腱及其相关神经血管束的相对位置在屈伸过程中发生了显著变化。
