Spiral Fracture lower tibial,upper fibula..Cast-no surgery

Hello my name is Ricky. About 2 weeks ago i managed to fracture both my Tibial and fibula. It was a closed spiral fracture and did not puncture the skin. The tibial fracture is about 3-4 inches above my ankle and fibula is right near the top closer to the knee. Now I was placed in a splint for about 2 weeks the was on my full leg above the knee. Now i just came back from the orthopedic and have a full leg cast on. We took xrays with the splint on and the fracture was still a little off place, so then i had the cast out on and was xrayed again, yet they did arch my foot up more and place a bend in my knee. After the cast was on they did another xray and my bone was still in place but now even more out of place, not by much but noticeable. I have done some research to see recovery times and i seen it will be months before the cast can be removed and another month if not more in physical therapy to get a full range of motion and movement back to a normal level. Now my doctor told me i can either go about this 1 of 2 ways..First being the hard cast for about 2 months or surgery. Now this is where i need the help. He said surgery would make the recovery time a lot quicker. He did mention risk of infections and problems with anesthesia with the procedure involving placing a rod down my shin bone and holding it in with pins. So basically my question is which way would be the best for me and overall recovery of my leg? I've only been in this hard cast for half a day and i cannot stand it nor the fact of staying in it for a few months. Also the fact of knowing the sever loss of muscle mass and strength. Now i didn't get much information on the surgery procedure and what is involved, so any more information on how to go about this would be great. Thank You
