Abstract
De Quervain tenosynovitis (DQT) was first discovered by Swiss surgeon Fritz de Quervain in 1895. It is a condition that affects the first extensor compartment of the wrist, resulting in stenosing tenosynovitis. The condition causes thickening of the sheaths that encompass the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendons as they traverse through their fibro-osseous tunnel, which is located along the radial styloid.(1)
De Quervain tendinopathy usually affects females, more than males, aged 30-50 years. Risk factors include overuse, such as knitting, sewing, dish washing, and phone texting. It can also occur post traumatic, or postpartum.(2)
Patients usually present with radial-sided wrist pain aggravated by thumb and wrist movement. Patients face difficulty in performing daily tasks such as opening a jar lid and lifting objects. Pain over the radial styloid along with fusiform swelling are appreciated as well.(3)
Diagnosis can be made clinically by the presence of radial sided wrist pain along with swelling. Special tests such as Finkelstein test, Eichhoff test, and WHAT test aid in the diagnosis. X-rays are of no diagnostic value but may show generalized signs and can aid in ruling out other causes of pain such as fracture, and arthritis. Ultrasound and MRI scans are the diagnostic radiological modalities for this condition.(4, 5)
The treatment regimens consist of non-operative methods and operative one. The non-operative methods, include immobilization and local injection.(6)
The administration of corticosteroid injections for musculoskeletal ailments gained widespread acceptance during the 1950s. While the efficacy of this therapy is commonly due to the anti-inflammatory properties of corticosteroids, the precise mechanism of action remains uncertain, as histopathological analysis fails to reveal any evidence of inflammation.(7)
In contemporary medical practice, platelet-rich plasma (PRP) injections are emerging as a viable option for the treatment of tendinopathies that have proven to be resistant to conservative management strategies.(8)
Conservative management through NSAIDS, Splinting, injection are all methods proven to be effective as a first line of management of this condition. In case of failure of conservative management, Surgery is usually performed as a last resort in an outpatient setting.(9)
