These are demanding procedures for the surgeon, which take 2.5 to 3 hours. The key to success in these cases is the correction of the ulna – reconstruction of its articular surface, restoration of its axis and length, and subsequent fitting with a plate. Then continue with the reconstruction of the upper end of the spoke. If it is possible to assemble the fragments, we use a plate for fixation as in the ulna; if this is not possible, we replace the upper end of the radius with an endoprosthesis. Only after perfect restoration of the original shape of both bones does the patient have hope for future full function of the affected limb.
