OPin good company with crashes.
In brief my last accident was broken femur At age 72. Rode 13,0000 lie since.. Lessons learned were many. Like the advice to find a doc who rides.
Anyways 1) Do PT and keep it up as long as suggested if not more; 2) When ready start on a trainer or spinning at the gym to build. Up strength and heart lung. Safer than on the road; 3) Only if ready ride easy on road. Your body will tell yu when you are ready; Ride with a friend to start.
All this assume you want to ride again and your are convinced it will be safe. RemInds me what my doc said when broke collar. Bone about safety riding. He said it’s safe to ride, just not safe to fall.
You already knw we re all different so no one proves works for all. Best of luck and take your time.
