Study Notes

Carpal Tunnel Syndrome Overview

The median nerve is primarily affected in carpal tunnel syndrome.
Females are more commonly affected than males in carpal tunnel syndrome cases.

Carpal Tunnel Anatomy

The carpal tunnel comprises the carpal bones and the transverse carpal ligament.
Typically, there are nine flexor tendons present within the carpal tunnel.
In addition to the median nerve, the carpal tunnel houses flexor tendons and the synovial sheaths surrounding them.

Consequences of Increased Pressure

Increased pressure within the carpal tunnel can lead to nerve compression, causing pain, numbness, and weakness in the hand.

Risk Factors

Evidence-informed biological risk factors associated with carpal tunnel syndrome include repetitive wrist movements, obesity, diabetes, and hormonal changes.

Clinical Characteristics

A clinical characteristic of carpal tunnel syndrome includes pain and tingling in the thumb, index, and middle fingers.
"Median claw hand deformity" occurs due to complete paralysis of the thenar muscles.

Symptoms and Management

Symptoms worsen at night, often leading to disturbed sleep patterns.
Suggested management for median nerve entrapments includes activity modification and physical therapy.

Splinting and Surgical Intervention

A wrist splint is recommended to reduce nerve compression in carpal tunnel syndrome.
Individuals with severe symptoms or persistent impairment despite conservative measures should be referred for surgical intervention.

Pharmacological Treatment

Nonsteroidal anti-inflammatory drugs (NSAIDs) can be used to relieve pain and inflammation in carpal tunnel syndrome.

Rehabilitation Strategies

'Graded muscle stretching' is recommended to improve flexibility and reduce symptoms in carpal tunnel syndrome.
