Focus on a MSD #6 –<\/strong> De Quervain’s tenosynovitis<\/h1>\n<\/div><\/div>
<\/div>

Today, we’re taking a closer look at a musculoskeletal disorder (MSD) that is often overlooked compared with other wrist and hand conditions: De Quervain’s tenosynovitis.<\/span><\/p>\n

This MSD affects the tendons at the base of the thumb and can make everyday tasks as well as work-related activities painful and difficult.<\/p>\n

In this new MSD focus, we’ll explore how this condition develops, its symptoms and risk factors, as well as the key approaches to prevention and treatment.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

De Quervain’s tenosynovitis is a condition characterized by inflammation and swelling of the tendons, or their surrounding sheath, at the base of the thumb.<\/p>\n

It affects two tendons that are essential for thumb movement: the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). These tendons enable the thumb to move away from the hand and play a key role in gripping, pinching and grasping movements.<\/p>\n

The condition is named after the Swiss surgeon Fritz de Quervain, who first described it in 1895.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

Spotlight: Understanding the different hand and wrist syndromes<\/strong><\/em><\/p>\n

Several musculoskeletal disorders can affect the hand and wrist:<\/span><\/p>\n

\u2192 De Quervain’s tenosynovitis:<\/strong> affects the tendons at the base of the thumb, causing pain during gripping, pinching and grasping movements.<\/p>\n

\u2192 Carpal tunnel syndrome:<\/strong> compression of a nerve at the wrist that can cause tingling, numbness and loss of sensation in the fingers.<\/p>\n

\u2192 Guyon’s canal syndrome<\/strong> (also known as ulnar tunnel syndrome): compression of a nerve at the wrist (on the little finger side), leading to sensory and\/or motor disturbances in some fingers.<\/p>\n<\/div><\/div>

<\/div>

There is limited precise epidemiological data on De Quervain’s tenosynovitis, which explains the relatively small number of available figures.<\/span><\/p>\n

In France, a study conducted among 3,710 employees between 2002 and 2005 estimated a prevalence of 1.2% in the working population, with a higher frequency in women (2.1%) than in men (0.6%).<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

De Quervain’s tenosynovitis:<\/strong> Symptoms<\/span><\/h2>\n

The main symptom of De Quervain’s tenosynovitis is pain located on the outer side of the wrist, at the base of the thumb. It usually develops gradually and becomes worse during movements that involve the thumb or wrist.<\/p>\n
