Abstract

Purpose

To demonstrate the usefulness of ultrasonography (US) in the detection of anatomic variations in the first extensor compartment of the wrist in patients with de Quervain disease.

Materials and Methods

The institutional review board approved this study protocol and waived the informed consent requirement. Fifteen wrists in 13 women (age range, 41–62   years) in whom de Quervain disease was clinically diagnosed and who underwent surgery for intractable pain were included. A musculoskeletal radiologist performed US before surgery. The absence or presence and extent of subcompartmentalization within the first extensor compartment and the number of abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendon slips were evaluated and recorded. Preoperative US findings were compared with surgical records and photographs.
