Question
I was bornj with a arm disorder, it makes the lenght of my arm shorter than is appropriate for my size and it unable me to open up my palm. This is because the joint conecting the lower and and upper part of my arm is defective at birth.Please can you tell me the name of this disease and any other details i need to know?

Answer
Unfortunately, I can't answer your question because there are several diseases that can result in problems with the upper extremities.  I can only suggest that you ask your doctor what the specific condition is and what precautions that you might need to follow.

Thank you for your question, Paul.  I hope that my answer leads you to more appropriate information.
