摘要
目的:虽然髂后嵴常被用于不稳定型骨盆骨折的固定,我们对髂后嵴进行解剖测量探讨骶骨棒内置的安全性。方法:共解剖32具尸体标本,男18具,女14具,从L5椎板上缘至两侧髂后上棘不同水平测量腰骶管至双侧髂后嵴顶点连线的距离。结果:发现所有标本从L5椎板上缘至两侧髂后上棘水平间其距离都大于要求的12mm安全距离,最大距离位于L5-S1接合处水平,在髂后上棘水平以下平均距离为8.88mm。结论:从L5椎板上缘至两侧髂后上棘间的髂后嵴区域安全且骨质量较好可用于骶骨棒的安全、有效固定,在髂后上棘水平以下安装骶骨棒是危险的。
Objective： The posterior iliac crest is frequently used for posterior stabilization of unstable pelvic fractures. Anatomic dissections were done to evaluate the size of the posterior iliac crest and the satety and feasibility of the intra-saeral rod insertion. Methods： Thirty-two cadavers were dissected bilaterally. Eighteen were male and fourteen were temale. The distance between the posterior wall of the sacral canal and the tip of the iliac crest was measured at various levels between the. level of the upper border of L5 lamina to the level of the posterosuperior iliac spine. Results： In all the dissections the greatest distances were at the level of the L5-S1 junction, The average measured distance between the level of the upper border of L5 lamina to the level of the posterosuperior lilac spine were greater than 12 mm, which is the smallest sate. distance. Below the posterosuperior iliac spine level, the average measured distance was only 8.88 mm.. Conclusions：The entire length of the posterior lilac crest from the level of the upper border of L5 lamina to the posterosuperior lilac spine was shown to be the safest level for good bony purchase and appropriate for safe and solid sacral bar fixation, Below the postemsuperior iliac spine level, insertion of the sacral bars was dangerous.
