Wrong thread.Ulnar nerve contusion
What is an ulnar nerve contusion?
Ulnar nerve contusion is a bruising injury to the ulnar nerve, close to the skin’s surface at the elbow, from a direct blow. Contusions cause bleeding from ruptured capillaries that allow blood to infiltrate the nerve. Direct injury to the nerve causes damage even if bleeding of capillaries is not a factor. The contusion causes pain, hand weakness, and loss of feeling, often in the fourth and fifth fingers. Ulnar nerve dysfunction or inflammation may greatly decrease athletic performance in sports that require strong hand or wrist action.
