In your case, the wound does not heal, and the fracture of the calf itself can easily lead to the wound's non-healing due to blood supply problems. Fortunately, your wound is not infected. Eight months after the fracture, the fracture should heal. As for the treatment of wounds, we often use the following treatment methods:

1. Debridement and dressing change: Go to the hospital to remove the dry skin with a little necrosis or poor blood circulation at the edge of the wound, remember not to use too much, usually about 2 mm, then clean it, and then apply Shengji Yuhong ointment on the wound to promote the formation of fresh granulation tissue, and slowly change the dressing until it heals.

2. This is an operation, using the method of autologous skin flap transplantation. You can also design a suitable flap around the wound of the affected limb, transplant it to the wound for suture or choose a cross flap of the lower limb from the other leg. There are two kinds of flap transplantation: free flap transplantation and pedicled flap transplantation. Of course, in your present situation, it is best to transplant with pedicle, with high success rate. It's ok to do the pedicle breaking in three weeks.

I hope it helps you. If you have any questions, you can ask.

I wish you a speedy recovery!
