Healing for a little one

Please pray for a friend of mine's little boy named Zeke Norris,  He is a 17 month old baby.

They just did surgery to correct tibial pseudoarthrosis. He was born with a bent tibia, then it broke, and would not heal. They put him in a cast for 3 months, then a soft cast to heal the skin.  Since the surgery, he's in a spica cast but he'll switch to a single cast in a month. They got three different opinions from 3 different hospitals and felt this was the best chance for his leg to ever heal. All specialists that they have spoken with have told them that they can do all this and he may still have to have that leg amputated.  Please pray for complete healing. 
Thanks!  Christina Grace
