Had a double femur fracture with plate, dynamic hip screw etc last July and was in hospital for 10 days. A handful of suggestions:
Assuming you are not on crutches yet, or at least not without supervision from either a nurse or an HCA, a zimmer frame will help a bit to build up your hands and triceps, for when you leave on crutches.
I found getting in and out of bed was easier by straightening my legs and hooking my good leg's foot, under the ankle of the bad leg and using it as a guide/support. It could still hurt like hell, but I had much more control over the movement.
When you get to the stage of wanting to relieve your back by rolling to various degrees on your good side, use a pillow or two to support your good leg, so you don't roll too far and try putting a folded pillow or two between your knees. I found the pillow/s between my legs took some of the pressure off the damaged area. You might not be comfortable for very long, but it relieves your back.
After a few days and you start to manage the pain better, see if the nurses will let a visitor take you out occasionally in a wheelchair. Just getting off the ward, even if only for 5 minutes, can make a big difference.
I've probably got wussy hands, but some padded fingerless gloves helped break my hands in when I started on crutches..
