Tendovaginitis of the wrist, work-related

Definition
Wrist tendinitis is a clinical condition defined by pain, local swelling, redness, tenderness and sometimes crepitation in the wrist region.

The condition has many names that refer to the specifically affected tendon structure, but which in clinical practice are only confusing because the specific localization for inflammation cannot be determined. One possibility is to consistently name the condition tendinitis as here


 * Work-related de Quervain's tendinitis is treated separately

Occurrence
In epidemiological studies, different case definitions are used, which is why very different prevalences are reported among employees with and without wrist-loading work1 The acute wrist tendinitis with characteristic symptoms and clinical signs is rarely seen in cross-sectional studies of working people because the condition is short-lived. In contrast, recurrent persistent wrist pain with no signs of acute inflammation is common in professional groups with unilateral, repeated manual labor.

Occupational risk factors
Risk factors for developing wrist tendinitis are 1.	high repetitiveness 2.	exercise of force 3.	use of the hand in awkward positions or combinations thereof 4.	There are mainly cross-sectional studies but also a few follow-up studies for work-related reasons. Several of these show, despite extremelydifferent prevalence of the disease, an excess risk of these factors of 2-4 times, but there are also studies that can not demonstrate an excess risk2 5.	The condition is seen with increased incidence, among other things, in slaughterhouse workers, employees in the fishing industry, in packing work, in industrial seamstresses, in power-intensive assembly work and certain types of cleaning work. 6.
