Clinical Classification Guidelines
Medical Intelligence & Overview
An injury of the digital nerve of the thumb involves damage to the nerve responsible for sensation in the thumb, which can result from various types of trauma. The digital nerves are small nerves that run along each finger and thumb, providing feeling and sensation. When injured, symptoms may include numbness, tingling, or loss of sensation in the thumb. This condition is classified under ICD-10 code S64.30, indicating an unspecified injury to the digital nerve of the thumb. Digital nerve injuries can occur due to cuts, lacerations, crush injuries, or penetrating wounds. The severity varies from minor nerve irritation to complete nerve severance, which can lead to significant sensory deficits. Proper diagnosis and treatment are essential to restore function and minimize long-term complications.
