简介:对学习客观解剖并且biomechanical骶的小花梗和侧面的质量展示以便为骶的小花梗和侧面的质量的临床的螺丝钉固定技术提供参考。60成年病人骶骨和尾臀骨的螺线CT图象全部的方法A随机被选择。骶的小花梗和侧面的集体螺丝钉的入口点被决定,并且螺丝钉轨道用三个维的重建方法被测量。同时,粗野解剖在15个成年死尸标本被细看决定骶的小花梗和侧面的质量拧紧入口点。骶的小花梗和侧面的集体螺丝钉轨道的长度,宽度和角度被测量。15个死尸标本中的八个被选择测试骶的小花梗和侧面的集体螺丝钉的最大的抽取力量。小花梗和侧面的集体螺丝钉技术对待的15个盒子的临床的数据镇定、分析。结果S1-S5骶的小花梗和侧面的集体螺丝钉轨道的直径和长度是常规的,与大约20?牧潯敶吗?
简介:如果误诊,距骨的侧面的过程破裂是有一个潜力的稀罕损害引起重要病态。这些破裂的适当管理仍然是争论的,仅仅一些报告在这个题目上是可得到的。我们在在损害的时候被误诊的距骨的侧面的过程上与忽视的骨折介绍了37岁的男性的一个案例。长期的脚关节疼痛地在错误诊断以后介绍给7个月的病人。我们的案例在它是在湾穴tarsi作为松开的身体介绍了的距骨的侧面的过程上的忽视的骨折的一个稀罕案例的意义是唯一的。然而,有松开的身体的切除的一个手术与2years’一起介绍了令人满意的结果后续。到我们的知识,它应该是在英语文学报导的第一个案例。通过这份案例报告,当评估损伤到脚关节的侧面的方面时,我们为如此的稀罕多骨的损害强调怀疑的高索引的重要性并且讨论这些破裂的管理的原则。
