牵拉肘又称挠骨小头半脱位。多发生4岁以内幼儿,是一种常见病。临床容易误诊。近5年来,我们收治10例,报告如下。 临床资料:本组10例,男7例,女3例。年龄1～4岁,平均年龄2岁。左肘6例,右肘4例。牵拉伤8例,外伤2例。本组病例拍片阴性,均误诊为软组织损伤,误诊时间为1～3天。确诊后手法复位一次成功。随访6～12个月,肘关节活动正常。 误诊原因:①解剖因素:小儿环状韧带前下方附着点软弱,挠骨小头后外侧边缘低平,在旋前区用力牵拉前臂时,环状韧带前方破裂或松驰,桡骨小头向下自环状韧带内滑出,并向前向桡侧移位,将环状韧 Pull the elbow, also known as radial head subluxation. More children under 4 years of age is a common disease. Clinical easy to misdiagnosis. In the past five years, we received 10 cases, the report is as follows. Clinical data: The group of 10 patients, 7 males and 3 females. Age 1 to 4 years old, average age 2 years old. Left elbow in 6 cases, right elbow in 4 cases. Tension injury in 8 cases, 2 cases of trauma. This group of patients film negative, were misdiagnosed as soft tissue injury, misdiagnosis time was 1 to 3 days. After the diagnosis of a successful reset method. Follow-up 6 to 12 months, elbow activity was normal. Causes of misdiagnosis: ① anatomical factors: pediatric annular ligament before the bottom of the attachment point is weak, after the small radius of the lateral margin of the radial head bent, premature pronation area force to pull the forearm, the anterior annular ligament rupture or relaxation, radial head Sliding out of the annulus and moving forward to the radial side, the ring will be tough
