@dfspfs I don't mind answering any questions I can. His journey was challenging and absolutely unexpected but all the treatment choices were well worth the outcome.
Initially, he had very little range of motion in that arm. Worked with physical therapy for a long time and used every gadget they had. He still doesn't have full range, but can do basically anything he could do before. His surgeries were very extensive so he does have numbness from nerve damage. He definitely has scars, but that is a small price to pay. Part of his thigh is now his elbow. I'll add a couple pictures (back and side view) of what it looks like now. Compared to what it looked like 5 years ago, it's amazing.
