There's actually a post for that in the disABILITIES FAQs thread (page 2)
I copied the post for you:
If it is a rigid cast, that is a little different and harder to get into things than full leg brace (braces have at least some flexibility.
Someone who is not able to bend the leg at all might have very few attractions they can ride and may have to settle for shows. The wheelchair space In most of the wheelchair accessible ride cars is around 48 inches long.
So, if someone is using a wheelchair and has their leg extended out in front of them, they are likely to be longer than 48 inches.
My DD's personal wheelchair from the tips of her toes to the back of the push handles is almost 40 inches ( and she has little feet). Add a packed backpack, and her wheelchair is about 46 inches. Someone with longer feet or an extended leg might be longer than 48 inches in a wheelchair.
The attractions listed below
might have room for someone out of a wheelchair in a regular seat.
Wheelchairs can be brought all the way to the boarding area of most attractions.
Peter Pan and Tomorrowland Transit Authority have moving walkways which can't be slowed or stopped, so would not be accessible to someone with a long leg cast.
Disney used to have a FAQs on their website where they did list the attractions that had more room for a leg cast.
Besides size, you would need to check with the doctor for some - like Tower of Terror. Don't want to risk damage by jostling the leg too much. I removed the things that no longer exist, added the replacement in its place, if the ride car is the same/similar and added some notes about ride cars.
The following attractions have additional space on aisle ways or next to the seating areas and should be able to accommodate a full leg cast. Please speak with a Cast Member at each of these locations for additional information.
Magic Kingdom
- Walt Disney World Railroad (has a wheelchair space in the front car and should fit)

Disney-MGM Studios
- Star Tours (check with doctor) - would need to transfer to a ride seat
- Twilight Zone Tower of Terror (check with doctor)
- For the a First Time in Forever - A Frozen Singalong

- Star Wars - movie and wheelchair accessible walk thru displays
- Walt Disney, One Man's Dream - museum like attraction
- Toy Story Mania - has a wheelchair accessible car, but it is fairly tight and wheelchair with leg extended will not fit. If able to get on, beware of the bar that holds the pop gun used during the ride; my daughter has ended up with it crashed into her knee while it was being secured.
Animal Kingdom
- Kilimanjaro Safaris - wheelchair accessible ride car may fit
- Pangani Forest Exploration Trail
- Wildlife Express to Conservation Station
- Festival of the Lion King
For MKSomeone with a long leg cast may not be able to get into Splash Mountain or possibly Pirates because the ride cars are pretty tight. Pirates, possibly is not an easy step in, but might be doable with a long leg cast or brace.
Splash has a very high step over the side, so would probably not work.
Haunted Mansion would probably not work - possibly would work in his own ride car.
Buzz Lightyear and Aladdin have wheelchair cars, but both a tight and the regular car does not have much leg room, although someone with a long leg cast might fit in a row by himself, sitting partly sideways.
The Great Goofini is a small short roller coaster and does not look like it would have space.
For Epcot, Mission Space ride car is fairly tight, so he may not fit and would not have the option of a ride car for himself, but maybe it would work if there were less than 4 in the ride car and if OK with his doctor (even green version can move you around).
Spaceship Earth is also fairly tight, although the walk in is flat.
Maelstrom in Norway is about the same to get into as Splash Mountain - tight and high step over the side.
For the Studio, Toy Story Midway Mania has a wheelchair car, but someone may not fit with a long leg cast. My DD's wheelchair is a fairly tight fit.
They may or may not fit if transferring to the regular ride car, but would have to use the accessible boarding area anyway to avoid the stairs in the regular line.
For AK, if he gets the OK from his doctor and has a waterproof cast, a person with a long leg cast may be able to ride Kali River Rpids. It won't be easy in or out, but they have a special boarding area for guests with disabilities where they trap a boat so it stays still. I would not recommend it though - the water in the boat makes things slippery and the chance of getting totally soaked is great.
Expedition Everest is another one to ask the doctor about. The ride car is pretty tight, but there is a practice car guests can try to see if they would fit.
Dinosaur is very rough and fairly tight.
I would highly recommend skipping Primeval Whirl. It is rough and jostles riders around a lot. Without binging able to use the leg, the rider would not be able to brace very well and would be jostled more than usual.
For most of the rides that require a transfer, the person will be getting in and out on the same side. So, if they are stepping in with the 'bad' leg going in last, they will step out with the bad leg coming out first. This is important to keep in mind because getting in may be easier than getting out (or vice versa).
