ligamenta

Two cases of hypertrophy of ligamenta flava at the L_3-L_5 level undergoing surgical operation were reported, both gaining satisfactory result.

手术治疗两例L3～L5黄韧带肥厚症患者，收到满意效果。

Results: According to the macroscopical pathological features, ossification of ligamenta flava could be recognized as nodular ( hyperplasia) type, peripheral type and diffuse type.

结果：根据大体形态特点可将黄韧带骨化分为结节型（增生性）骨化、周围型骨化和弥漫型骨化3种类型。

Methods 34 cases of normal human ligamenta flava were determined by salt precipitation, the collagen samples were analyzed by SDS-PAGE.

方法用盐析法对34个正常黄韧带标本中的Ⅰ型和Ⅱ型胶原含量进行测定，并用SDS-PAGE法进行胶原的分型确定。

Objective The type-I and type-II collagen contents in the normal ligamenta flava and the clinical significance of them were investigated.

目的研究人正常黄韧带中Ⅰ型和Ⅱ型胶原含量，探讨临床意义。

Smple fenestration was adopted to resect the ligamenta flava to treat retro-Lumbar spinal stenosis for 36 cases.

采用单纯开窗,黄韧带切除手术,治疗退形性腰椎管狭窄症36例.

Operative Treatment of Hypertrophy of Ligamenta Flava ( L_3& L_5). Report of Two Cases

L3-L5黄韧带肥厚症手术治疗二例

Conclusions: The macroscopical type of the lesion indicates the different stage in development of the ossification of ligamenta flava.

结论：黄韧带骨化的大体类型代表着同一病变发展的不同阶段；
