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?

검증된 단계별 안내

Understand that carpal tunnel syndrome is caused by compression of the median nerve as it passes through the carpal tunnel in the wrist.

Recall that the carpal tunnel is a narrow passageway on the palmar side (front) of the wrist, formed by carpal bones and the flexor retinaculum (a strong fibrous band).

Recognize that symptoms like numbness and pain in the hand, especially in the thumb, index, middle, and part of the ring finger, are due to median nerve compression in this area.

Know that a splint for carpal tunnel syndrome is applied to immobilize the wrist, keeping it in a neutral or slightly extended position to reduce pressure on the median nerve.

Therefore, Mr. Harvey will apply the splint around his wrist, specifically over the palmar side, to stabilize the wrist and relieve symptoms.

Carpal Tunnel Syndrome

Carpal tunnel syndrome is a condition caused by compression of the median nerve as it passes through the carpal tunnel in the wrist. It leads to symptoms like numbness, tingling, and pain in the hand, especially affecting the thumb, index, middle, and part of the ring finger.

Anatomy of the Carpal Tunnel

The carpal tunnel is a narrow passageway in the wrist formed by carpal bones and the transverse carpal ligament. It houses the median nerve and tendons that control finger movement. Understanding its location is essential for targeting treatment like splint placement.

Purpose and Placement of a Splint in Carpal Tunnel Syndrome

A splint for carpal tunnel syndrome is applied to the wrist to keep it in a neutral position, reducing pressure on the median nerve. It immobilizes the wrist, preventing flexion or extension that can worsen symptoms, and is typically worn during activities or at night.
