Ulnar Claw

Ulnar Claw (pronounced: UHL-nahr klaw), also known as Ulnar Claw Hand or Claw Hand, is a deformity of the hand that develops due to ulnar nerve damage. The ulnar nerve is one of the three main nerves in the arm and it travels from the shoulder to the little finger.

Etymology

The term "Ulnar Claw" is derived from the Latin word "ulna", meaning "elbow", and the Old English word "clawu", meaning "claw". The condition is named so because it affects the ulnar nerve, which runs along the inner side of the arm and hand, and causes the fingers to bend in a way that resembles a claw.

Symptoms

The primary symptom of Ulnar Claw is a deformity in the hand where the ring and little fingers bend towards the palm, resembling a claw. This is often accompanied by weakness and a loss of fine motor skills in the hand. Other symptoms may include numbness, tingling, and pain in the hand or arm.

Causes

Ulnar Claw is typically caused by damage to the ulnar nerve, which can occur due to a variety of reasons such as elbow or wrist injuries, pressure on the nerve from prolonged elbow bending, or conditions that damage nerves such as diabetes or autoimmune diseases.

Treatment

Treatment for Ulnar Claw primarily involves addressing the underlying cause of the nerve damage. This may include physical therapy, medication, or in severe cases, surgery.
