Sulcata Shell Burn help

My fault, I rescued a 60 pound Sulcata tortoise two years ago and all been well he is now just over 95lbs. Living in Alaska brings many challenges when trying to care for reptiles. Harry has a run of the 1 acre fenced yard and for 5 months out the year he is in heaven. His last owner could not care for him so I took him on. I winter him in my basement.
Last summer Harry got himself caught under my deck and damaged his front scutes. The two front scutes were peeled back and exposed the bone underneath there was no bleeding and no subsequent infections. So I left it alone. I changed heating my bulb and noticed that the area seemed to be injured. It looks like a burn but now the area around where the shell was damaged is dried and sealed. You can see the bone under where the scutes used to be. It’s the very top of the scutes and does not seem to interfere with his new growth.
I have changed my light and moved to a 150 watt heat emitted (12” above his shell) that keep his shell temp above now @ 85.5. He eats and moves fine and is doing well.
Is there anything I can do and will it heal if I just leave it alone? I’ll be moving him to the barn once I complete my reptile room. He will be with my new Black Throat Monitor. Feel like an idiot that I did not check temps I just assumed same bulb will provide same temps. NOT!

how about a picture of the ara that is burnt? maybe put aloe on it or neosporin to help it heal.

Sulcata can easily handle a basking spot with surface temps of 100*+. I think that your problem is that a one bulb basking area for a 24" tortoise isn't going to cut it. You're probably going to need to use 3-4 bulbs placed in a pattern to create a nice large spot. Good care sheets for monitors will illustrate how to arrange the lights for nice big basking areas. Additionally, I would add a livestock heat mat to a hide in your enclosure if you don't already have one. Kane and Stanfield make some very reliable ones. Sulcata will opt to use belly heat over basking spots for large portions of the day/night and having a pad will reduce the likelihood that your tortoise will hang out long enough under a lamp to burn itself again.

Also, I hope that "with" your monitor doesn't actually mean "with" your monitor. Monitors are amazingly intelligent apex predators. Your sulcata is a big bruiser, but he's an active and curious bruiser that a monitor could quickly learn to kill. And even if your tortoise remains unharmed for a long time, sleeping in the same enclosure with a predator is going to cause a lot of stress which could result in illness or death for the tortoise.

For the burn, just keep it clean and apply a topical like neosporin and it should heal up nicely. Keep the wound uncovered to discourage infection.

Good advice I will follow through on. its healing nice its dried out and seems clean and free of infections.

He's doing great, talked to my vet and an a few others on some Herp forums and its best to leave it alone. The burn is only on the very top of two front scutes and are the ones prone to damage. The burns are completly dried and there is no sign of infection. Its been raining here and he is none to happy about not getting out in the sun.
