[Irreducible physeal fracture of the distal radius due to entrapment of the extensor pollicis longus. A case report]. / Fractura fisaria de radio distal irreducible por atrapamiento del extensor pollicis longus. Reporte de un caso.

We present a clinical case of entrapment of the extensor pollicis longus at the level of the fracture site in a distal radius epiphysiolysthesis. The active mobility deficit of the patient's thumb, pain upon passive mobility, and the X-rays should make us suspect this lesion.
