目的通过对髋臼唇进行解剖学测量,分析髋臼唇的解剖学特点及其临床意义。方法通过10具经甲醛溶液防腐处理的骨盆标本,解剖其髋臼结构,测量15个标点的盂唇宽度并对其形态进行观察。结果臼顶与前壁、臼顶与后壁对应的髋臼唇宽度比较,无统计学差异(P>0.05)。后壁与后方结构、后壁与前壁对应的髋臼唇缘宽度比较,有统计学差异(P<0.05)。髋臼唇组织十分致密、坚韧,外观上与腱性组织相似,断面呈三角形,基底增厚并附着在髋臼骨性结构上,与髋臼月状软骨边缘移行。结论髋臼唇作为髋臼正常解剖结构中的一个组成部分,具有重要的生理功能和生物力学意义。对髋臼唇的损伤我们不应轻易进行切除,而应尽可能对其进行修补或重新固定的手术治疗。
Objective To analyze the anatomic features of acetabular labial lip and its clinical significance by anatomical measurement of acetabular lip. Methods Ten pelvic specimens preserved with formalin solution were dissected and their acetabular structures were dissected. The labrum width of 15 punctual points was measured and its morphology was observed. Results There was no significant difference in acetabular lip width between mortar and anterior wall, acetabulum and posterior wall (P> 0.05). There were significant differences in the lip width of the acetabulum between the posterior and posterior structures, posterior wall and anterior wall (P <0.05). Acetabular lip tissue is very dense, tough, appearance and tendon similar tissue, triangular cross section, the basement thickening and attached to the acetabular bony structure, and acetabular crescent cartilage edge migration. Conclusion Acetabular lip, as an integral part of the normal anatomy of the acetabulum, has important physiological and biomechanical significance. We should not easily resection the acetabular lip injury, but should be as much as possible to repair or re-fixed surgical treatment.
