A dissection-based study of 18 embalmed cadavers (7 male, 11 female), mean age 84 (+/-8.4) years.
To determine the morphology and morphometry of the anterior dural (Hofmann) ligaments.
The attachment of the posterior longitudinal ligament to the dura mater is poorly understood. Anterior dural ligaments connect the anterior dura to the deep layer of the posterior longitudinal ligament, but appear to be limited to the lumbar region and have been observed to have a craniocaudal orientation. Their function is reported to help in supporting and protecting the dural sac and spinal cord.
The spinal canal was opened exposing the dural sac, the spinal nerve roots incised, and spinal cord removed to mobilize the dural sac and gain access to Hofmann ligaments. The extent, orientation, length, and level of origin and insertion of the ligaments were documented.
The orientation of the ligaments changed from caudocranial (dura to posterior longitudinal ligament) at upper thoracic levels to transverse at the level of T8-T9 to craniocaudal at lower thoracic and lumbar levels, often with multiple ligaments being present at a single level. Ligament length varied from 0.5 to 28.8 mm and was positively correlated with vertebral level and negatively correlated with orientation.
Hofmann ligaments are present at most levels between C7 and L5; although most ligaments were limited to a single vertebral segment, some were observed to cross several segments.

确定硬脊膜前（霍夫曼）韧带的形态和形态测量。
后纵韧带与硬脊膜的附着情况尚不清楚。硬脊膜前韧带将硬脊膜前部与后纵韧带深层相连，但似乎仅限于腰椎区域，且观察到其呈头尾方向。据报道，它们的功能有助于支撑和保护硬脊膜囊和脊髓。
打开椎管暴露硬脊膜囊，切断脊神经根，移除脊髓以移动硬脊膜囊并显露霍夫曼韧带。记录韧带的范围、方向、长度以及起始和插入的水平。
韧带的方向在上胸段从尾头方向（硬脊膜至后纵韧带）变为T8 - T9水平的横向方向，在下胸段和腰段变为头尾方向，通常在单个水平存在多条韧带。韧带长度从0.5至28.8毫米不等，与椎体水平呈正相关，与方向呈负相关。
霍夫曼韧带存在于C7至L5的大多数节段；尽管大多数韧带局限于单个椎体节段，但观察到一些韧带跨越多个节段。
