Understanding Wrist Drop (Acquired): Causes, Symptoms, and Treatment
Wrist drop is a condition that results in the inability to extend the wrist and fingers. The condition can be acquired or congenital. Acquired wrist drop is more common and is usually caused by nerve damage or injury. In this article, we'll explore the causes, symptoms, and treatment options for acquired wrist drop.
- Causes of Acquired Wrist Drop
- Radial nerve injury: This is the most common cause of acquired wrist drop. The radial nerve runs from the neck down to the hand, and it controls the movements of the wrist, fingers, and thumb. Injury to the radial nerve can occur due to trauma, compression, or stretching.
- Fracture: A fracture in the arm or wrist can damage the radial nerve and lead to wrist drop.
- Compression: Prolonged pressure on the radial nerve, such as leaning on the arm for an extended period, can lead to nerve damage and wrist drop.
- Neurological disorders: Certain neurological disorders such as Guillain-Barre syndrome and multiple sclerosis can cause nerve damage and lead to wrist drop.
- Symptoms of Acquired Wrist Drop
- Inability to extend the wrist and fingers
- Weakness in the arm and hand
- Numbness or tingling in the arm and hand
- Pain in the arm and wrist
- Treatment of Acquired Wrist Drop
- Physical therapy: This is the most common treatment for wrist drop. A physical therapist can help to strengthen the muscles in the arm and wrist and improve range of motion.
- Splints or braces: These can be used to support the wrist and keep it in a neutral position.
- Surgery: In severe cases, surgery may be necessary to repair the damaged nerve or to relieve pressure on the nerve.
- Medications: Pain relievers or anti-inflammatory drugs may be prescribed to relieve pain and inflammation.
If you are experiencing wrist drop symptoms, it's important to see a doctor for an accurate diagnosis and appropriate treatment. With proper treatment, most people with acquired wrist drop can regain full use of their arm and hand.
