About

The purposes of this study are to compare the effectiveness and side effects of US-guided and palpation-guided corticosteroid injections for de Quervain's disease.

Full description

De Quervain's disease is a common clinical disorder, characterized by pain at radial side of the wrist. It often interferes wrist and thumb movement, and may affect activity of daily life. It is caused by overuse and impaired gliding of the abductor pollicis longus (APL) and extensor policis brevis (EPB) tendons at the styloid process of the radius. It is associated with postpartum baby care, or jobs or hobbies that involve repetitive hand and wrist motions. The most effective treatment is corticosteroid injection into the tendon sheath of the conjoined tendons of APL and EPB. Over the past few years because of advancement of sonography in the musculoskeletal system, ultrasound (US)-guided intra-sheath injection has become popular, and it has been proved to improve the accuracy of placement of needle tip in the tendon sheath, however, studies comparing the effect and side effects of US-guided corticosteroid injection with palpation-guided injection for de Quervain's disease have never been reported before. The purposes of this study are to compare the effectiveness and side effects of US-guided and palpation-guided corticosteroid injections for de Quervain's disease.

The investigators plan to recruit 70 patients with de Quervain's disease, half of them will be randomly assigned into US-guided injection group, and the other half into the palpation-guided injection group. Each subject will receive one shot of injection and each subject will expect to fill in the evaluation form at baseline, and at 1 week, 3 months, and 6 months after the injection. Statistics will be performed after completing the patients' treatment and evaluations.

49 participants in 2 patient groups

palpation-guided injection

Active Comparator group

Description:

Injectate: a mixture of 10mg triamcinolone acetonide (10mg/1ml) and 0.3ml 1% lidocaine. For palpation-guided injection, a 2.5cm 25-gauge needle will be inserted almost horizontally between APL and EPB tendons, just distal to the radial styloid, at the site of maximum tenderness. Then the mixture of triamcinolone and lidocaine will be pushed into the common tendon sheath.

Treatment:

Procedure: palpation-guided injection

US-guided injection

Active Comparator group

Description:

For US-guided injection, a 22 MHZ linear array probe (Esaote MyLab™ClassC, Italy) will be used for guidance of injection via a transverse scan, in-plane approach. After sterilization, the probe will be placed at the radial styloid with maximal swelling or tenderness. Then a 2.5 cm 25-gauge needle will be placed into the tendon sheath via transverse scan, in-the-plane approach, and the injectate will be pushed into the tendon sheath. Care will be taken avoiding injury of vessels and the superficial branch of radial nerve during the injection.

Treatment:

Procedure: US-guided injection
