The 36-year-old posted a number of x-rays of the injury, just days after he shattered his right tibia and fibula.
Hall eventually won via first-round TKO after referee Herb Dean stopped the contest but there was little celebration from the winner, who looked stunned by the events.
Speaking after the fight, Hall admitted he has "nothing but respect" for Weidman and branded him "truly one of the best."
Weidman was quickly scooped onto a strecher as 15,000 people in attendance at the VyStar Veterans Memorial Arena in Jacksonville, Florida, gasped in horror after seeing replays of the leg break.
Just three days after the horror injury and Weidman looks to be in good spirits following surgery on Tuesday.
He posted before and after X-rays "of this nightmare" incident, writing on his Instagram page: "Special thanks to Dr. Gitlin for performing a successful surgery and being so helpful during the entire process."
"Also, a big thank you to Dr. Davidson from the UFC for making sure I was taken care of properly and speaking to these doctors on my behalf. It made me feel so much better having him involved because I know he had my back."
Weidman went on to explain the next steps in his recovery. He said: "The primary concern is the bone punctured through my calf and skin when I put my weight on it, making sure the laceration doesn't get infected."
In another post on social media hours later, Weidman thanked UFC president Dana White for his efforts after the event.
"I can't thank Dana White and UFC enough for taking care of my family and me during these challenging times." he said.
"These are the sort of things they do for us that people don't get to see. Instead of being in pain on a public plane or stuck in a car forever, they chartered us a plane straight from the hospital to our house.
"Also very thankful to have Ufc medical coordinator @every1lovesraimond who stayed in Jacksonville the entire time to make sure I was good. Grateful to my management @vaynersports Lloyd and @sarahzemonek. So grateful.
It's great to see Weidman on what is set to be a long road to recovery.
