Abstract

The posterior ligaments: ligamentum flavum, articular, interspinous and supraspinous ligaments of twenty five fresh cadaveric intervertebral segments, from T11-T12 to L4-L5, extracted from fourteen spines were tested in tension. A progressive dissection method was used, that is, each segment was tested after first resecting the disk with the ligaments intact and a force-elongation curve obtained. Then one ligament was cut and the test repeated, and so on. The most restrictive ligament was found to be the ligamentum flavum followed by the articular, interspinous, and supraspinous ligaments.

摘要

对从14个脊柱中提取的25个新鲜尸体的胸椎11 - 12至腰椎4 - 5节段的后韧带(黄韧带、关节突关节韧带、棘间韧带和棘上韧带)进行拉伸测试。采用逐步解剖法,即每个节段先在韧带完整的情况下切除椎间盘后进行测试并获得力-伸长曲线。然后切断一条韧带并重复测试,依此类推。结果发现限制作用最强的韧带是黄韧带,其次是关节突关节韧带、棘间韧带和棘上韧带。
