Fractura triplanar del extremo distal del radio: reporte de caso / Triplanar fracture of the distal end of the radius: case report

ABSTRACT

Triplanar fractures are those that occur in 3 separate planes at the end of an immature long bone. They typically cross the epiphysis in the sagittal plane, physis in the transverse plane, and metaphysis in the coronal plane. Due to their nature, they are considered an intra-articular injury. Radiographically, these fractures often resemble a Salter-Harris type III epiphyseal slip injury on the anterior-posterior view and a Salter-Harris type II on the lateral view and are consequently considered a Salter-Harris type IV. Only 5 cases of triplanar fracture of the distal end of the radius have been reported so far in the literature, the second case managed with open reduction and internal fixation is reported. This is a 12-year-old patient with a history of trauma to the right wrist after a traffic accident, with deformity and functional limitation and diagnostic images that confirm a fracture at the metaphyseal level of the distal end of the right radius with radial displacement and a stroke. fracture that goes through the epiphysis, physis and metaphysis. An open reduction and internal fixation was performed. 2 years after the injury, the patient is asymptomatic, with preserved ranges of joint mobility and diagnostic images with evidence of adequate consolidation of the fracture, absence of alteration of the physis and consequent normal growth of the radius. Level of Evidence IV.
