This patient has a radius shaft segmental fracture with nonunion, healed soft tissue with scar, nerve and probably tendon injuries but a well perfused hand, probably not infected and an intact ulna.
This would most commonly be treated with plate fixation of the radius shaft and the bone would typically heal in good position and give the best chance at optimal recovery of the various soft tissue problems.
Although one could argue for intramedullary fixation on a theoretical basis, plates work very well on the radius shaft in both practice and theory.
At 5 months post injury you could either reduce the distal nonunion and span the intercalary segment (4 screws in the proximal and distal fragments) accepting some imperfect alignment at the proximal fracture site or take down the "nascent imperfect" union at the proximal fracture site. Although the fracture may be "healed", by carefully scraping away the callus you can typically develop the original fracture line and improve the reduction in the manner of Jupiter and distal radius "nascent" malunions. The callus will provide adequate bone graft to fill the apparent small bone defect at the distal nounion site.
Restoring length, rotation and stability immediately and obtaining ultimate bone healing will greatly enhance the potential for soft tissue recovery. (in contrast to accepting a chronic nonunion around some kind of small intramedullary device).
To me, there is a good treatment option available with reasonably good chance of success and no need to try something innovative.
