Textbook Question

Mr. Harvey, a computer programmer, has been complaining of numbness and pain in his right hand. The nurse practitioner diagnosed his problem as carpal tunnel syndrome and prescribed use of a splint. Where will Mr. Harvey apply the splint?

Verified step by step guidance

Understand the condition: Carpal tunnel syndrome occurs when the median nerve, which runs through the carpal tunnel in the wrist, becomes compressed. This can lead to symptoms such as numbness, tingling, and pain in the hand and fingers.

Identify the location of the carpal tunnel: The carpal tunnel is located on the palmar side of the wrist. It is a narrow passageway formed by the carpal bones and the transverse carpal ligament.

Determine the purpose of the splint: A splint is used to immobilize the wrist in a neutral position to reduce pressure on the median nerve and alleviate symptoms.

Locate where the splint should be applied: The splint should be applied to the wrist, ensuring that it supports the wrist in a neutral position (not flexed or extended). This position minimizes compression of the median nerve.

Ensure proper usage: Mr. Harvey should wear the splint as prescribed by the nurse practitioner, typically during activities that exacerbate symptoms or while sleeping, to prevent wrist movement and allow the nerve to heal.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Carpal Tunnel Syndrome

Carpal tunnel syndrome is a condition caused by compression of the median nerve as it travels through the wrist's carpal tunnel. Symptoms include numbness, tingling, and pain in the hand and fingers, particularly affecting the thumb, index, and middle fingers. Understanding this condition is crucial for recognizing the need for interventions like splinting.

Wrist Splinting

Wrist splinting is a common treatment for carpal tunnel syndrome, designed to immobilize the wrist and reduce pressure on the median nerve. The splint is typically worn at night or during activities that exacerbate symptoms. Proper application of the splint is essential for effective symptom relief and prevention of further nerve damage.

Anatomy of the Wrist

Understanding the anatomy of the wrist is important for applying a splint correctly. The carpal tunnel is located on the palm side of the wrist, where the median nerve and tendons pass through. Knowing the location of the carpal tunnel helps in positioning the splint to ensure it provides adequate support and alleviates pressure on the affected nerve.
