Dear Praful,
You seem to be having a series of instrumentation problems!!
I would probably leave it alone till the fracture unites and then address the issue of broken drill bit during implant remoal and only if there are some problems to it. In other words no action now. You have not told us age of the patient and any other co-morbidities. These factors also may affect the decision making later.
