Tibia and fibula bone compound fracture.

Hi I met with an accident on 17/04/2019 and operated on 19/04/2019 and doctor fitted rod in my leg with 2 screws both side. On 30/08/2019 i had a X-ray I attached in the attachment in that it is showing my bone still not joined . It is almost 5 months. I want to go for job also and it is also been 5 months that I didn't go for job. I want to ask how much more time it will take that i can go back to my job. I have deep cut under the back side of foot (eddy) where i get 15 stiches. Now the outer part of the wound is okay and stick together but inside that wound it is not healed properly. When i walk more on that it is like spoonge type very soft . When i didn't walk it is hard. But there is no pain only sometimes. Please help me for both the case and suggest me any medicine or any diet to join the bones together or anything to recover the tissues of the wound. Waiting for your answers. Thanks Vikas
