You can stabilize that foundation wall to prevent further movement using carbon fiber straps. The rest of the crack you fill with hydro cement.

Call local contractor who specialize in such repairs and they will give you the price. Depending on prep-work, etc the prices vary, average cost is about $400 per strap which are installed 4' on center including material and labor so in your case it will be approximately 4-5 straps.

My neighbors had their foundation repaired. They replaced (built new foundation walls) the front and one side of the house. I believe they said it was $20,000. Plus having to spend a week in a hotel due to the gas and water line had to be disconnected while the wall was being repaired. They also had to replace a bathroom and re-finish their game room. Most of the foundation failure in our area is due to improper foundation back fill /drainage and the clay soil/water pushing in the foundation. Straps for our area sounds like a band aid. It doesn't correct the problem of why the foundation failed in the first place. I am in PA.
