【摘要】 肱骨远端全骺分离骨折为儿童肘部损伤中少见损伤,常与肱骨髁上骨折和婴幼儿的肘关节脱位相混淆。本文报告12例,占同期肱骨远端骨骺损伤的7.1%。12例中骨骺内移9例、外科3例。根据X线片和手术发现,属Salter-Harris Ⅰ型8例、Ⅱ型3例、Ⅴ型1例。骨骺碎裂为2块或3块者4例,其中1例兼有压缩。手法复位5例,手法整复失败或陈旧损伤,行切开复位7例。结果6例满意、3例较好,3例肘关节活动受限明显。12例中肘内翻5°～14°者4例,前臂无不稳现象。本文还就病因、损伤机理、诊断和鉴别诊断等问题进行了讨论。更多还原

【Abstract】 Fracture—separation of the distal numeral epiphysis is rarely seen among injuries of the elbow in childnood aud very comonly it is misdiagnosed as a supracondylar humeral fracture and elbow dislocation in infant。In this group 12 cases were reported.In same during 7.1 per cent was occupied.Nine of 12 of fracture—separation of the distal humeral epiphysis with medial displacement and 3 cases with lateral displacement were reported.Accoring to X—Ray films and findings on operation,belong to TypeⅠ eight cases,TypeⅡ three,Type Ⅴ one by Salter—Harris were presented classificat on.Four of them of two or three piceses broken and among only one pressed of the distal humeral epiphysis,five cases with perfect closed reduction sucess- fully and immobilization,seven cases with open reduction and interner fixation while closed reduction unsuccess and/or old fracture.The results in nine cases were excellent,three were better,and three elbow joints movement were limited.There were a 5—14° varus deformity which fortunately caused no obvious disability of the arm.The mechanism of injury,causes,diagnosis,and differential diagnosis were discussed更多还原
