背景:拇指指间关节脱位的常见治疗方法是闭合复位,但是有些不能通过在指间关节中插入芝麻骨或足底板而减少,这种情况需要公开减少。
方法:在病例1中,患者是一个17岁的男孩,当摩托车摔倒在他的右拇指上时受伤。X线显示Miki2型IP关节脱位。因为闭合还原失败,通过背侧入路切开复位术至halluxIP关节.在病例2中,患者是一个17岁的男孩,他在走路时被车撞了。X线显示Miki2型halluxIP关节背侧脱位。关闭还原后,X线和CT显示IP关节脱位由Miki2型变为1型。通过背侧入路进行切开复位。
结论:15例Miki2型在闭合复位后转变为1型,1型位错经常被忽视,导致一些慢性病例。重新定位后应进行X射线检查,特别是在横向和斜视图。
结论:我们经历了2例无法复位的髋关节脱位。我们的一个病例从Miki2型重新分类为1型,但我们没有忽视失败的闭合还原,我们做了CT.因此,我们建议额外的侧视X射线和/或CT成像。
BACKGROUND: The common treatment for hallux interphalangeal joint dislocation is closed reduction, but some cannot be reduced by interposition of the sesamoid or the plantar plate in the interphalangeal joint, and such cases need open reduction.
METHODS: In
case 1, the patient was a 17-year-old boy who was injured when a motorcycle fell on his right hallux. X-ray revealed Miki type 2 IP joint dislocation. Because closed reduction failed, open reduction via the dorsal approach to the hallux IP joint was performed. In
case 2, the patient was a 17-year-old boy who was hit by a car whilst walking. X-ray revealed Miki type 2 dorsal dislocation of the hallux IP joint. After closed reduction, X-ray and CT revealed that the IP joint dislocation changed from Miki type 2 to type 1. Open reduction was performed through the dorsal approach.
CONCLUSIONS: Fifteen cases of Miki type 2 changed to type 1 after closed reduction, and type 1 dislocation is often overlooked, leading to some chronic cases. X-rays should be performed after repositioning, specifically in lateral and oblique views.
CONCLUSIONS: We experienced two cases of irreducible dislocation of the hallux IP joint. One of our cases was reclassified from Miki type 2 to type 1, but we did not overlook the failed closed reduction, as we performed CT. Hence, we recommend additional lateral-view X-rays and/or CT imaging.
