Ulnar nerve injury

The ulnar nerve is one of the important peripheral nerves in the upper limb, running from the axilla along the medial side to the hand. It is primarily responsible for the movement of specific muscles in the upper limb and sensation in localized skin areas. Ulnar nerve injury can result from external forces such as compression, traction, or tearing at any point along its course. Ulnar nerve injury mainly manifests as sensory and motor dysfunction.
