    在脚上,腰椎弯曲meta趾关节并延伸指间关节。已知在神经病中受影响的腰椎药。尚不清楚它们是否会在正常人中退化。这里,我们报告了我们在两个尸体看似正常的脚部中发现的孤立性退化的腰椎。我们在死亡时年龄为60-80岁的20名男性尸体和8名女性尸体中探索了Lumbricals。作为例行解剖的一部分,我们暴露了指长屈肌和腰椎的肌腱。从退化的腰部看,我们取了一些组织做石蜡包埋,切片,用苏木精和伊红染色,和Masson的三色技术。在所研究的224种医用兴奋剂中,我们在两具男性尸体中发现了四具明显退化的腰椎.在第一,左脚的第2和第4个腰椎和右脚的第2个腰椎退化。在第二个,右侧第4个腰椎退化。微观上,退化的组织是由胶原蛋白束组成的。由于神经供应的压缩,lumbricals可能已经退化。我们无法评论脚的功能是否受到这些孤立的腰椎变性的影响。
    In the foot, the lumbricals flex the metatarsophalangeal joints and extend the interphalangeal joints. The lumbricals are known to be affected in neuropathies. It is not known whether they may degenerate in normal individuals. Here, we report our findings of isolated degenerated lumbricals in seemingly normal feet of two cadavers. We explored lumbricals in 20 male and 8 female cadavers that were 60-80 years of age at the time of death. As part of routine dissection, we exposed the tendons of the flexor digitorum longus and the lumbricals. From the degenerated lumbricals, we took some tissue for paraffin-embedding, sectioning, and staining by hematoxylin and eosin, and Masson\'s trichrome technique. Of the 224 lumbricals studied, we found four apparently degenerated lumbricals in two male cadavers. In the first, the 2nd and 4th lumbricals in the left foot and the 2nd in the right foot were degenerated. In the second, the right 4th lumbrical was degenerated. Microscopically, the degenerated tissue was made of bundles of collagen. The lumbricals may have degenerated due to compression of their nerve supply. We cannot comment on whether the functionality of the feet were affected by these isolated degeneration of the lumbricals.
