Carpal Tunnel Syndrome (CTS)

Carpal Tunnel Syndrome (CTS) is a medical condition that occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes compressed at the wrist. This compression leads to symptoms such as pain, numbness, and tingling in the hand and arm.

Explanation

Carpal Tunnel Syndrome is significant within the context of occupational health and safety as it is one of the most common work-related musculoskeletal disorders. It often arises from repetitive hand movements, prolonged wrist flexion, or other ergonomic risk factors associated with certain jobs, such as assembly line work, typing, or using hand tools. Understanding CTS is crucial for employers and employees to implement preventive measures, promote ergonomic practices, and ensure a safe working environment.

Practical Examples

  • Manufacturing: Workers on assembly lines frequently perform repetitive tasks that can lead to CTS. For instance, a factory employee assembling small parts may develop CTS due to the repetitive motion of gripping and manipulating tools.
  • Office Work: A data entry clerk who spends long hours typing without proper wrist support may experience symptoms of CTS, leading to decreased productivity and potential long-term disability.
  • Healthcare: Surgeons and other medical professionals who perform repetitive hand movements during procedures may also be at risk for developing CTS.

Synonyms and Acronyms

  • Synonyms: Median nerve compression, wrist nerve entrapment
  • Acronyms: CTS

TermDefinitionKey Differences
TendonitisInflammation of a tendon, often due to overuse.Tendonitis affects the tendons rather than nerves, whereas CTS specifically involves nerve compression.
Cubital Tunnel SyndromeCompression of the ulnar nerve at the elbow.Cubital Tunnel Syndrome affects a different nerve and location (elbow), leading to different symptoms and causes.
De Quervain’s TenosynovitisInflammation of the tendons on the thumb side of the wrist.Primarily affects the tendons rather than the median nerve, with distinct symptoms and treatment approaches.

Related Concepts

  • Ergonomics: The study of designing equipment and workplaces to fit the worker, reducing the risk of injury.
  • Repetitive Strain Injury (RSI): A broader category of injuries that occur from repetitive motion, of which CTS is a specific type.
  • Workplace Safety: Policies and practices aimed at ensuring a safe work environment, including the prevention of musculoskeletal disorders.
