Wrist drop

Wrist Drop

Wrist drop (pronounced: /ˈrɪst drɒp/), also known as radial nerve palsy, is a medical condition characterized by the inability to lift the hand at the wrist. The condition is typically caused by damage to the radial nerve, which controls movement and sensation in the arm and hand.

Etymology

The term "wrist drop" is derived from the English words "wrist", referring to the joint connecting the hand to the forearm, and "drop", indicating a downward movement or position. The term accurately describes the primary symptom of the condition, which is a drooping wrist.

Symptoms

The primary symptom of wrist drop is the inability to lift the hand at the wrist. This can result in the hand hanging limp from the arm. Other symptoms may include numbness or tingling in the arm or hand, weakness in the arm or hand, and difficulty with finger movement.

Causes

Wrist drop is typically caused by damage to the radial nerve, which can occur due to a variety of factors. These may include direct injury to the nerve, prolonged pressure on the nerve, or conditions that cause nerve inflammation, such as rheumatoid arthritis or diabetes.

Treatment

Treatment for wrist drop typically involves addressing the underlying cause of the nerve damage. This may include physical therapy, medication, or in some cases, surgery. In cases where the nerve cannot be repaired, assistive devices such as braces or splints may be used to support the wrist and improve function.
