The lateral side of the base of the second (SMT), third (TMT), and fourth (FMT) metatarsal bones displays constant and distinct grooves. The groove on SMT starts just above the middle of the lateral surface of the base and runs toward the shaft forming an angle of 85-111 degrees with the base. TMT has a groove starting at about the middle of the lateral surface forming an angle of 57-72 degrees with the base, while the groove on FMT runs upward more acutely, starting from the lower end of the surface, forming an angle of 37-54 degrees with the base. The presence of these grooves and the usefulness of their characteristics in distinguishing between these metatarsals, especially in forensic medicine, is discussed.
第二（SMT）、第三（TMT）和第四（FMT）跖骨基部的外侧有恒定且明显的凹槽。SMT上的凹槽始于基部外侧表面中部上方，朝着骨干延伸，与基部形成85 - 111度的角度。TMT的凹槽始于外侧表面中部左右，与基部形成57 - 72度的角度，而FMT上的凹槽从表面下端开始向上延伸得更为陡峭，与基部形成37 - 54度的角度。本文讨论了这些凹槽的存在及其特征在区分这些跖骨方面的用途，尤其是在法医学中的用途。
