In response to the enquiries: “Purple fingers and fractured wrist” and “Is it common for fingers to turn purple after wrist surgery?”
Yes, it is rather common for the fingers to turn blue or purple after wrist fracture and after wrist and carpal tunnel surgery.
The fracture and the surgery damage blood vessels and blood flow to the palms and fingers is obstructed. Dead and dying blood remains in the vessels of the fingers and the palms and it turns blue. The blue color indicates that there is no more oxygen in the blood that stays in the hand.
Soak the hand and fingers in hot water, massage to get fresh circulation going, and use vapor rub on the fingers and hands to stimulate blood flow and elasticity of the blood vessels.
