It is more than 2 and half months since the injury.. Normally it should have been healed by now.
As per the x ray pic, there are visible signs if fracture healing but a doubtful line can be seen in some views which creates a doubt regarding complete union.
Next Steps
If you are not having any pain, you may start with partial weight bearing walking with support (placing just toes on the floor).. if there is no pain, you can start full weight bearing after 10 days..
If the pain increases, stop weight bearing and get a repeat x ray..
Health Tips
Use a crepe bandage for support as there is a possibility of local swelling when you start walking.. crepe bandage will help in preventing that..
