case_images: Anteroposterior and lateral X-rays of the left wrist showed a displaced Salter-Harris type IV fracture of the distal ulna (Figures 1(a) and 1(b)). CT showed a displaced fracture through the epiphysis and metaphysis on the volar side of the distal ulna with an intraarticular step of 3 mm (Figure 1(c)).

case_images: A third pin was drilled in the anteroposterior plane through the distal fragment (Figure 2).
case_images: Anteroposterior and lateral X-ray 2 weeks after surgery.

case_images: Follow-up after two weeks showed a favourable clinical evolution with maintained position of the fracture fragments on X-ray (Figure 3).
case_images: Anteroposterior and lateral X-ray 6 months after surgery. Two pins have been removed. No physeal closure visible.

case_images: X-ray of the wrist showed the fracture was fully healed with no evidence for premature fusion of the physis or growth arrest (Figure 4).
case_images: Anterioposterior and lateral X-ray 1 year after surgery shows premature physeal closure and mild negative ulnar variance.

case_images: X-ray 1 year postoperatively showed complete closure of the physis with development of a negative ulnar variance (Figure 5).
