Hi, welcome to HCM.
Clot due trauma can be resolved. It depends on size and location of clot. Also what amount of clot has been removed in operation. If extradural or subdural haematoma
is aspirated then recovery will be fast. Otherwise It will take time to resolve at least 6 to 8 month.
Important treatment in such patients is physiotherapy
. It will improve the power of lower limb.
Hope I have answered your query.
