What is the correct treatment for a conminuted fracture of the radius and ulna?

The surgeon decides on a minimally invasive technique due to the presence of bone comminution and soft callus that make anatomical reduction of the fragments impossible.
A small incision is made medial to the fracture site to remove the cerclage wire and intramedullary nail.
A sample is taken for bacteriological culture and antibiogram.
A tunnel is made with blunt Metzenbaum scissors between the extensor tendons and the radius, through which a locked plate is inserted.
The plate is fixed with two screws to the distal fragment and three screws to the proximal fragment.
Another locked plate is placed orthogonally to the first and on the lateral surface of the ulna to increase stability.
A bacterial culture is negative, so antibiotic administration is discontinued.
At four months post-surgery, positive bone activity, maintenance of alignment, and absence of implant complications are observed.
The incorrect planning of this case, in which inadequate techniques and implants were used for the management of this fracture, resulted in a delay in bone consolidation.
The correct option in this case would have been to place two plates, one on the radius and one on the ulna, as was done later.
