Previous studies concerning the level of termination of the human spinal cord have been carried out in unselected cadavers. We have used magnetic resonance imaging to determine this level of termination, and that of the dural sac, in normal living subjects. We found a wider range of the level of termination of both the spinal cord and dural sac and a higher median level of termination of each than is commonly described. These anatomical findings are of clinical relevance to clinicians practicing regional anesthesia.
以往关于人类脊髓终止水平的研究是在未经挑选的尸体上进行的。我们利用磁共振成像来确定正常活体受试者中脊髓和硬脊膜囊的终止水平。我们发现脊髓和硬脊膜囊的终止水平范围比通常描述的更宽，且各自的中位终止水平更高。这些解剖学发现对从事区域麻醉的临床医生具有临床相关性。
