骶髂关节韧带应用解剖学意义

背景：骨盆后部结构中,骶髂后韧带复合体、骶结节韧带和骶棘韧带的完整,对骨盆稳定性有重要作用.目的：观察骶髂关节周围韧带解剖结构,了解各韧带对关节稳定性的作用.方法：对20具防腐成年尸体骨盆标本,共40侧依次采用前后方入路,对骶棘韧带,骶结节韧带,耻骨联合及骶髂关节诸韧带结构进行解剖学观察.结果与结论：骶髂关节周围韧带可分为3组：骶髂前韧带、骶髂骨间韧带和骶髂后韧带.耻骨上下韧带及耻骨前后韧带.骶棘韧带和骶结节韧带.此3组韧带主要有两个功能：连接脊柱和骨盆环;维持骨盆环的稳定.

Applied anatomy of the sacroiliac ligaments

BACKGROUND：Complete structure of the sacroiliac complex,the sacrotuberous ligament and the sacrospinous ligament in the back of the pelvis is important to the stability of the pelvis.OBJECTIVE：To observe the structure of the sacroiliac joint ligaments and study the functions of the ligaments on the stability of the sacroiliac joint.METHODS：The sacrospinous ligament,sacrotuberous ligament,and pubic symphysis and the ligaments of the sacroiliac joint from 20 embalmed pelvis specimens were observed via the anterioposterior approach to study their anatomical structure.RESULTS AND CONCLUSION：The sacroiliac joint ligaments can be divided into three groups：the anterior sacroiliac ligaments,the interosseous sacroiliac ligaments and the posterior sacroiliac ligaments;the symphysis pubis ligaments;the sacrospinous and sacrotuberous ligaments.These ligaments have two main functions.They can connect the vertebral column with the pelvic,and maintain the stability of the pelvic ring.
