2.5 months ago, I had multiple fractures in BOTH my upper arms & elbows following a fall from a cycle (as well as a fracture in right shoulder & 3 cracked ribs). Some of the humerus pieces had even "jumped". I had extensive surgery (plates, pins, screws, wires), but I have the same problem as you guys, i.e. lack of movement in the elbows. I have only about 110 deg flexion & 110 deg extension in both arms. I'm having physio 3 x a week, but progress seems to be very limited.
BTW, as a lay person, I am unable to understand your medical terminology. I would be most grateful if you could explain it in layman's terms.
Thanks
