Patient's question:
The palm cannot be up, just the left hand cannot flip, the right hand is normal, this problem was recently discovered.Doctor's answer:
The symptoms you described are likely to be a condition called proximal ulnar-radius synostosis. If it is confirmed to be this condition, unfortunately, there is no treatment available (i.e., achieving the purpose of self-flipping movement of the palm).However, it can be checked to see if surgical treatment can be attempted.
