摘　　要：目的研究足第1蚓状肌的解剖结构并测量相关数据，为携带第1蚓状肌足趾移植修复拇、手指缺损提供解剖学基础依据，并探讨足部第1蚓状肌的形态学功能。方法2016年3月-2018年1月．对50只福尔马林固定的足进行系统且细致的解剖．观察第1蚓状肌起止点的确切位置．用游标卡尺进行测量相关数据．并进行统计学分析。结果第1蚓状肌起于第2趾的趾长屈肌腱内侧，肌腹长度为[55．87±8．67（79．30～41．16）1mm；肌腱的止点具有两处，第1止点在近节趾骨底的内侧结节，第2止点为趾背腱膜，以内侧结节为标志点，将肌腱分为近侧及远侧段。近侧段的长度、宽度及厚度分别为[15．34±4．81（5．52～25．18）]mm、[2．31±1．12（3．28-1．21）1mm、[0．44±0．14（0．28-0．68）]mm；远侧段的长度、宽度及厚度分别为[11．51±4．06（3．46～14．90）]mm、[6．10±1．44（9．36～3．70）]mm、[0．18±0．09（1．10～0．38）]mm。近侧段的长度及厚度明显大于远侧段，差异有统计学意义（P〈0．05）。结论第l蚓状肌具有维持运动时足趾、足弓的平衡及稳定：屈跖趾关节、伸趾骨间关节、内收第2趾：足部运动时防止第2趾旋外的作用。Objective To investigate the anatomical structure of the first plantar lumbrical muscle in the foot and to measure the relevant data which could provide anatomical basis for repairing thumb and finger defects with the transplantation of toes accompanied with the first lumbrical muscle,and to explore the marphologieal function of the first lumbrical muscle of the foot. Methods From March, 2016 to January, 2018, a systematic and detailed dissec- tion of the 50 formalin-fixed feet was performed to observe the exact position of the starting and ending points of the first lumbrical muscle, and a Vernier caloper was used to measure the relevant record data. Results The first lum- brical muscle originates from the medial portion of the flexor digitorum lungus tendon of the second toe, and the length of the ventral muscle was [55.87±8.67（79.30-41.16] mm. There were 2 endpoints in the tendon. The first one was in the medial tubercle of the proximal phalanges. The second one was aponeurosis of the dorsal toe and the tendon was divided into proximal and distal segments with the medial tubercle as the mark point. The length of the proximal seg- ment was [15.34±4.81（5.52-25.18] ram, the width of the proximal segment was [2.31±1.12（3.28-1.21）] ram, the thick- ness was [0.44±0.14（0.28-0.68）] mm; the length of the distal segment was [11.51±4.06（3.46-14.90）] ram, the width was [6.10±1.44（9.36-3.70）] mm, and the thickness was [0.18±0.09（1.10-0.38）] mm. The length and thickness of the proximal segment was siguifantly larger than those of the distal segment （P〈0.05）. Conclusion The first lumbrical muscle has the function of maintaining the balance and stability of both the toe and the arch during movement, flexur- ing the metatarsophalangeal joint, extending the interosseous joint of the extensor phalangeal, adducting the second toe; also the function of preventing the second toe from oronation during foots＂ movement.
