Fractures of the lateral condyle of the humerus classified as type IV in Salter schema are difficult to diagnose when the capitellum is not ossified. Therefore it is necessary to know exactly the radiological lines which are constructed from the humerus and the radius to the capitellum. Diagnosis is also difficult when the ossification center of the capitellum humeri is only slightly displaced. The epiphyseal fracture line which is always visible at surgery can be missed on X-Ray when ossification has not yet appeared. Laminograms are necessary in some cases to be sure that the fracture is displaced. Displaced fractures are always treated by open reduction.
按照萨尔特分型为IV型的肱骨外侧髁骨折，在肱骨小头未骨化时很难诊断。因此，必须准确了解从肱骨、桡骨至肱骨小头所构建的放射学线。当肱骨小头的骨化中心仅有轻微移位时，诊断也很困难。手术时总能看到的骨骺骨折线，在骨化尚未出现时X线片上可能会漏诊。在某些情况下，需要进行断层摄影以确定骨折是否移位。移位骨折总是采用切开复位治疗。
