BACKGROUND
The anatomy of the first metatarsophalangeal (MTP) joint, particularly the metatarsosesamoid articulation, remains poorly understood. Our goal was to quantitatively define the excursion of the sesamoids.
METHODS
Seven cadavers were dissected to assess the articulating surfaces throughout a normal range of motion. The dissections were digitally reconstructed in various positions using a MicroScribe.
RESULT
For first MTP joint, excursion averaged 14.7mm for the tibial sesamoid in the sagittal plane and 7.5mm for the fibular sesamoid. The sesamoids also moved medially to laterally when the joint was dorsiflexed. For the maximally dorsiflexed joint, excursion averaged 2.8mm for the tibial sesamoid and 3.5mm for the fibular sesamoid.
CONCLUSION
Hallucal sesamoids appear to have differential tracking: the tibial sesamoid has greater longitudinal excursion; the fibular sesamoid has greater lateral excursion. The anatomical data will interest those involved with the design of an effective hallux arthroplasty.
背景
第一跖趾关节（MTP）的解剖结构，尤其是跖籽骨关节，目前仍知之甚少。我们的目标是定量确定籽骨的移动范围。
方法
解剖7具尸体，以评估在正常运动范围内的关节面。使用MicroScribe在不同位置对解剖结构进行数字重建。
结果
对于第一跖趾关节，在矢状面，胫骨籽骨的移动平均为14.7毫米，腓骨籽骨为7.5毫米。当关节背屈时，籽骨也会从内侧向外侧移动。对于最大背屈的关节，胫骨籽骨的移动平均为2.8毫米，腓骨籽骨为3.5毫米。
结论
拇趾籽骨似乎有不同的运动轨迹：胫骨籽骨有更大的纵向移动；腓骨籽骨有更大的横向移动。这些解剖学数据将引起那些参与有效拇趾关节置换术设计的人员的兴趣。
