I fractured my radial head in August - only a class 1 fracture, but it was missed in the general horror of my wrist/hand, and only found in October after physio pointed out I had limited forearm rotation.
Despite loads of physio, I still have limited pronation, and hardly any supination even with someone trying to force it. No problems with flexion/extension apart from it locking sometimes and lots of crunching.
MRI was normal, and hand specialist/physio/hand therapists are a bit baffled as to what is causing it.
As there always seems to be someone here with experience, I wondered it anyone had any bright ideas, or recommendations for an elbow super expert ? Its suprisingly annoying esp as it reduces the few useful things I can do with that arm, so am keen to seek ideas.
