[Proximal tibial fractures]

Only 1-4% of all long bone fractures in children involve the proximal tibia. To evaluate these fractures appropriately, it is mandatory to differentiate between articular fractures and metaphyseal fractures. Articular fractures of the proximal physis are rare and include Salter Harris type III and IV injuries. The reconstruction of the articular surface is the fundamental goal of therapy. Injuries of the anterior crucial ligament which typically appear as an avulsion of the tibial spine and the avulsion fracture of the tibial tubercle apophysis can involve the articular surface. Dislocated fractures should be reduced and stabilized. Extraarticular fractures include Salter Harris type I and II fractures. Other types of metaphyseal fractures are the complete fracture, the compression fracture and the bending fracture of the proximal tibia. Care should be taken while treating bending fractures, especially a valgus deformity must be excluded. Due to unequal growth stimulation during remodelling, a progressive valgus deformity frequently develops. Small deformities in the sagittal plane can be compensated by spontaneous remodelling during further growth. Dislocated fractures should be reduced and stabilized by K-wires. The retention of bending fractures by a compression plate or external fixator for medial compression might be more beneficial.
