[Limb emergencies in children].
The three main categories of limb emergencies are trauma, infection and the painful hip. Conventional radiography is used as the initial screening imaging modality that can sometimes be complemented with sonography. Computed tomography and MRI are rarely needed. Familiarity with conditions specific to the pediatric population is essential to the diagnosis and management of these patients. Traumatic injuries in children involve growing bones with large cartilaginous component and biomechanical resistance different from that in adults. Lim infections in children are affected by the characteristic vascular supply to the metaphyseal-epiphyseal region, the intra-articular location of the metaphysis, and loose periosteal attachment. Limping (transient synovitis, Legg-Calvé-Perthes disease and slipped capital femoral epiphysis) is frequent cause of consultation and diagnosis relies on the patient's age and plain film findings.
