hi yossarian,

at the outset I wonder why you were on cast for "9 weeks" for fracture lower end of radius and ulnar styloid.

anyway, post-traumatic stiffness is a known phenomenon so don't panic. from your post I understand that your range of motion (ROM) is grossly limited.

well, I would advice you to seek a competent physiotherapist's help to aid mobilization as self exercises alone will not suffice.

apart from manual therapy, your physio "will" put you on a strict home based exercise regimen. kindly follow the same religiously to regain your "full" range of motion.

all the best.

cheers,

thomas
