下图为最初的x线片和三个月、六个月复查的x线片。

2.at what age does the lateral condyle typically ossify?

肱骨外髁骨化中心出现的年龄?

10

12

never

3.which category of salter-harris fracture is this considered to be?

此例骨骺损伤的salter-harris分型?

type i

type ii

type iii

type iv

选择题答案:

findings

there is a left lateral condylar fracture, with anterior fat pad sign. fragment is less than 2 mm displaced. radial head is in place. follow-up imaging reveals bony bridging compatible with healing.

肱骨外侧髁骨折伴前方脂肪垫征阳性。骨片移位小于2mm。桡骨小头在位。复查x线示骨痂形成、愈合良好。

differential diagnosis

normal ossification center正常骨化中心radial head dislocation桡骨小头脱位medial condylar fracture内髁骨折lateral condylar fracture外髁骨折

diagnosis

lateral condylar elbow fracture肘关节外髁骨折

key points

lateral condylar elbow fracture is the second most common pediatric elbow fracture (15%).肘关节外髁骨折是儿童第二常见的肘部骨折(15%)。seen most often from ages 4 to 10, with peak incidence at age 6.常见于4岁-10岁,发病高峰年龄为6岁。usually related to a fall on an outstretched hand with the elbow extended and the forearm abducted.多于摔倒时手臂伸展有关,一般是前臂相对固定、肘关节过伸所致。considered to be a salter-harris type iv injury.该损伤属于salter-harris iv型。stage or type i fractures with less than 2 mm displacement can be treated with immobilization.移位小于2mm的i型损伤一般采取固定治疗。open reduction recommended for all type ii or iii fractures.salter-harris ii型或iii型,推荐切开复位。easily missed if thought to represent a normal ossification center. the lateral condyle does not ossify until age 10.如果误认为这是一个正常的骨化中心,则很可能漏诊该病。实际上,在10岁之前,这里不会出现骨化中心。
