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。
