U have already taken cast now that is good.
Cast Should be done in this type of fracture since day 1 .
First 7 days slab then continue cast .
But its ok .
Now according to my treatment plan u should do
Immobilisation-- Continue below-knee cast
Weight bearing -- Strict non-weight bearing
Duration --Another 3–4 weeks
Crutches Use for mobilisation
Ankle exercises -- Toe movements; ankle ROM after cast removal
Follow-up Repeat X-ray at 3-4 weeks weeks from injury
