I had ulnar shortening along with wrist arthroscopic surgery on August 19. Was in a cast for six weeks. This Thursday went back again and had another x-ray. The ulnar bone is not healing. (guess this would be non union.) Know he has me in a hard splint, a bone growth stimulator for 10 hours a day , vitamin C & D to try and make the bone heal. Does anyone know what they would do if it still does't heal? More surgery or what? I am new to this group so I would appreciate any insight one could give.
