Capitellum fractures account for less than 1% of all elbow fractures. Their appearance on plain radiographs may be subtle. It is this combination of features that make these injuries easy to misdiagnose. Misdiagnosis of a nondisplaced capitellum fracture is significant because the capitellum does not have soft tissue attachments and can convert to a displaced fracture that will need surgery. Although a prior study has reported a high incidence of occult elbow fractures when elevated fat pads are present, it did not demonstrate an impact on management. Our case illustrates that because of the capitellum's propensity to displace, detecting fat pads and immobilizing the elbow may have a significant impact on outcome.
肱骨小头骨折占肘部骨折的比例不到 1%。它们在普通 X 光片上的表现可能很细微。正是这些特征的结合，使得这些损伤很容易被误诊。肱骨小头骨折的误诊意义重大，因为肱骨小头没有软组织附着，容易转化为需要手术的移位骨折。尽管先前的一项研究报告称，当出现高脂肪垫时，隐性肘部骨折的发生率很高，但并没有证明这对治疗有影响。我们的病例表明，由于肱骨小头有移位的倾向，因此检测脂肪垫并固定肘部可能对结果有重大影响。
