What exercise can you do with a fractured wrist while in a brace?

Cardio: While you cannot lift weights, you can still participate in cardio activities, such as running, hiking or stationary cycling.

Up to surgeon: Certainly limited range of motion exercises of the fingers with the splint in place will be allowed under the supervision of a therapist almost immediately after surgery or immobilization. Above and beyond that, it depends on the stability of the reduction and serial x-ray examination and monitoring of the fracture status.
