Sqad, He has Emphisemia Fibrosis so finds breathing difficult. On oxygen 16 hours a day. What i meant by clean brake is - has it broken without any jagged edges or is it misaligned and crooked. The latter may cause damage to inside flesh.
He probably has CPOD and is short of breath anyway and as far as an X-Ray is concerned without any evidence of extreme shortness of breath following the incident then it would be of little or no value....even if the fracture? showed up.
What is far more important than an X-Ray is to inject a dose of local anaesthetic into a painful spot, so as not to impair his already troubled breathing.
