Broken wrist with cast, running allowed?

broken wrist. Sometimes, but this depends on the stability of the fracture. Please discuss with your orthopedic surgeon.
Yes, carefully. Running is allowed. You must keep in mind however that the cast only provides some protection. If you were to fall, you could cause further damage to the wrist. Running on a treadmill is probably safer than running outside in that regard. The cast may have to be changed more frequently as a result of the sweat.
