Management of lateral condyle fractures of the humerus in children

Lateral condyle fracture of the humerus is the second most common paediatric elbow fracture and is often missed, which can result in severe consequences including malunion, growth arrest and tardy ulnar nerve palsy. The difficulty in managing this fracture stems from a lack of awareness and the often subtle findings on radiographs. Patients can also present with quite vague symptoms; clinicians who do not have a high index of suspicion may not investigate beyond the initial clinical assessment and could miss vital cues. This article provides a guide to managing this common paediatric fracture, from initial presentation to definitive treatment, and discusses the complications that can ensue if managed incorrectly.
