Thumb ultrasound: Technique and pathologies

View Article: PubMed Central - PubMed

ABSTRACT

Ultrasound is ideally suited for the assessment of complex anatomy and pathologies of the thumb. Focused and dynamic thumb ultrasound can provide a rapid real-time diagnosis and can be used for guided treatment in certain clinical situations. We present a simplified approach to scanning technique for thumb-related pathologies and illustrate a spectrum of common and uncommon pathologies encountered.

EPL tenosynovitis (A-D). Schematic diagram (A) of the extensor tendons of the wrist shows the common site of EPL tendinopathy (represented in red circle). Long axis (B) ultrasound at the level of the wrist shows fluid around the extensor pollicis longus (EPL) tendon (white arrows) with absence of fluid at the level of retinaculum (red arrow). Short (C) and long (D) axis ultrasound at interphalengeal joint level shows soft tissue thickening (arrow) around the EPL tendon (open arrow). Subcutaneous veins are normally seen over the extensor tendon (red arrow in d) and should not be confused with tenosynovial fluid

Figure 10: EPL tenosynovitis (A-D). Schematic diagram (A) of the extensor tendons of the wrist shows the common site of EPL tendinopathy (represented in red circle).

Mentions: Inflammation of the tendon sheath, called tenosynovitis, is common in patients with inflammatory arthritis. Ultrasound features of tenosynovitis are hypoechoic fluid in the tendon sheath, hyperemia on color or power Doppler (indicating active inflammation), and synovial hypertrophy with or without hypervascularization (indicating chronic disease). Fluid secondary to inflammation may accumulate proximal and distal to retinacula (for the extensor tendons) [Figure 10A and B] and pulleys (for flexor tendons) producing a lobulated appearance. Soft tissue thickening secondary to inflammation can also develop and surround the tendon [Figure 10C and D].
