(S65.3) Injury of deep palmar arch

Injury of the deep palmar arch occurs when the ulnar artery is damaged, usually due to a traumatic event such as a cut or laceration. the deep palmar arch is a network of blood vessels located in the palm of the hand which supply blood to the fingers and thumb. when the ulnar artery is damaged, blood flow to the fingers and thumb is reduced, resulting in reduced sensation and potential tissue death.

Injury of the deep palmar arch is caused by a disruption of the ulnar artery, which is part of the arch. this disruption can be caused by direct trauma to the area, or by a sudden increase in pressure, such as in a car accident. the disruption of the ulnar artery can cause reduced blood flow to the hand, leading to decreased sensation, pain, and possible numbness in the affected area. in severe cases, tissue death and necrosis can occur.
