Finger stiffness after operation, and this is caused by the doctor's mistake, negligence or improper operation, then the doctor needs to bear the responsibility.

Sometimes postoperative finger stiffness is caused by complications that cannot be completely avoided during operation, individual differences of patients, improper postoperative rehabilitation or other unpredictable factors.
