Ulnar Nerve Injury: Causes, Symptoms, and Treatment
Ulnar nerve injury at the upper arm level, also known as ulnar neuropathy, is a condition that affects the function of the ulnar nerve, which runs from the shoulder to the hand. This injury typically occurs due to direct trauma, compression, or repetitive motion, resulting in pain, tingling, weakness, and numbness along the inner side of the forearm and hand, particularly in the ring and little fingers.
People with ulnar nerve injury may experience difficulty with gripping objects, weakness in the hand muscles, and a claw-like deformity of the hand. The symptoms may worsen at night or during activities that involve bending the elbow or applying pressure on the affected arm.
Diagnosis of ulnar nerve injury involves a thorough physical examination, nerve conduction studies, and imaging tests. Treatment options include conservative measures such as rest, splinting, and physical therapy, as well as surgical interventions in severe cases. Early intervention is crucial for a better prognosis, as long-term nerve damage can lead to permanent loss of sensation and muscle control.
