Your injury sounds worse than the one I had. A stationary bike was part of my therapy, so I considered myself ready for riding my bike. I tilted the bike lower so I could lift my leg over it. I was too bored to care about the possibility that another crash could keep me off the bike for longer, or forever. That did not happen, but I was never a fast rider, and I stayed on flat terrain away from cars.
For protecting your hip, a recumbent trike may be your safest option, depending on seat height and relative pedal height.
