为给临床行枕颈融合内固定术提供解剖学资料,对50 块干燥完整的成人枕鳞下部的厚度进行了测量。结果表明枕鳞下部厚度不均匀,以枕外隆凸处最厚,为11 ～17 mm ,平均14 .3±2 .6 mm ;最薄部位位于枕外隆凸外下方小脑窝处,为1 .2 ～7 .6 mm ,平均2 .5 ±0 .7 mm 。骨质厚度从枕外隆凸起向外向下放射状递减,左、右无明显差异( P> 0 .05) 。同时对枕鳞下部厚度进行了分区和讨论,其中厚度大于8 mm 区域为枕颈融合枕骨螺钉内固定的最佳部位
To provide anatomical data for clinical occipitocervical fusion and internal fixation, the thickness of the lower part of the occipital scale in 50 dry adults was measured. The results showed that the thickness of the lower part of the occipital scale was not uniform. The thickest part of the occipital lobe was 11-17 mm with an average of 14.3 ± 2.6 mm. The thinnest part was located in the cerebellar fossa outside the outer part of the occipital lobe. .2 ~ 7 .6 mm, an average of 2.5 ± 0. .7 mm. The thickness of the bone decreased radially outward from the occipital protuberance, with no significant difference between left and right (P> 0.05). At the same time, the thickness of the lower part of the occipital scale was subdivided and discussed. The thickness of more than 8 mm was the best site for internal fixation of the occipital-cervical fusion occipital screw
