question: My dad who is 92y/o fell last week on his arm in which he had had elbow replacement surgery.  The x-ray shows that he has knocked everything loose and he cannot lift his arm at all, plus his shoulder is very sore.  He was diagnosed with congestive heart failure last year and I would like to know the risks involved and/or there other options besides the surgery???   He is not diabetic. Thank you, gail pate
