Non displaced or only mildly displaced simple fractures
of radius need not require any surgery and can do well in plaster for 8-10 weeks. sometimes along with fracture of radius there is displacement of the wrist joint (distal radioulnar joint) called Galleazies fracture which requires surgery.
Only a competent orthopedic surgeon can decide about your situation.
do not worry. delay of a week or two will not harm much as surgery ( if required) can be done later also. till ten keep plaster, elevate limb and activelY move your fingers. consult ortho surgeon ASAP.
