新生儿骨折的超声诊断

目的探讨超声诊断新生儿骨折的可行性及新生儿骨折的超声影像学特点。方法回顾性分析2018年1月至2019年6月间在北京市朝阳区妇幼保健院住院的30例骨折患儿的住院病因、骨折诊断的超声表现。同时比较超声与X射线检查诊断骨折的情况。结果30例骨折患儿中,29例(96.7%)为产伤性骨折,1例为肋骨骨折,考虑为代谢性骨病;锁骨骨折28例(93.3%),肱骨骨折1例(3.3%),肋骨骨折1例(3.3%)。超声检查可发现骨皮质连续性中断、断端错位或成角等,恢复期可见骨痂形成。30例均可通过超声检查发现。而X射线检查仅发现29例骨折(96.7%),1例锁骨骨折经X射线检查未发现异常。结论超声诊断新生儿骨折准确可靠,其主要超声影像学特点为骨皮质连续性中断、断端形成、错位或成角等。

Ultrasound diagnosis of neonatal fracture

Objective To investigate the feasibility and characteristics of ultrasound imaging in diagnosing fractures in neonates.Methods Thirty neonates with bone fracture in Beijing Chaoyang District Maternal and Child Healthcare Hospital during January 2018 to June 2019 were retrospectively recruited.The causes and ultrasound imaging features of these cases were analyzed.The ultrasound findings were compared with the results of X-ray examination.Results Among the 30 cases,29(96.7%)were diagnosed as fracture due to birth trauma,including 28(93.3%)of clavicle fracture and one(3.3%)of humerus fracture,and one(3.3%)with rib fracture probably caused by metabolic osteopathy.The ultrasound imaging characteristics included interruption of bone continuity,dislocation and/or angulation of fracture ends,and callus formation during recovery.All of the 30 cases were diagnosed by ultrasound.However,X-ray examination failed in the diagnosis of one clavicle fracture.Conclusions Ultrasound is an accurate and reliable method for the diagnosis of neonatal fracture.The main characteristics of ultrasound imaging include interruption of bone continuity,dislocation and/or angulation of fracture ends and callus formation.
