Clinical features
The elbow is swollen and deformed. There is tenderness over the lateral condyle. Passive flexion of the wrist (pulling on the extensors) may be painful.
X-ray
X-ray examination must include oblique views or else the full extent of the fracture may be missed. Two types of fracture are recognized and classified by Milch:
Type I: A fracture lateral to the trochlea: the elbow joint is not involved and is stable.
Type II: A fracture through the middle of the trochlea: this injury is more common; the elbow is unstable as the radius and ulna are carried along with the fragment.. The fragment is often grossly displaced and capsized, and it may carry with it a triangular piece of the metaphysis.Remember that the fragment (partly cartilaginous) is much larger than it seems on x-ray.

临床特征
肘部肿胀变形。外侧髁上有压痛。手腕被动屈曲(拉伸肌)可能会疼痛。
X射线
X光检查必须包括斜视,否则可能漏掉整个骨折范围。Milch将骨折分为两种类型:
I型:滑车外侧骨折:肘关节未受累,稳定。
II型:滑车中部骨折:这种损伤更常见;由于桡骨和尺骨与碎片一起携带,肘关节不稳定。。碎片经常严重移位翻了,它可能带着一块三角形的干骺端。记住碎片(部分软骨)比x光片上看起来要大得多。
