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.

A 55-year-old male with painful thumb abduction (A-F). Oblique radiograph (A) and reconstructed computed tomography–volume rendering technique image (B) of the thumb reveals subtle calcification along the lateral aspect of the base of proximal phalanx (arrow). Long axis (C) ultrasound of the thumb shows calcification (arrow) with heterogeneous hypoechoic area (open arrow) near the insertion of APB tendon. Axial T1 (D) and STIR (E) Magnetic resonance images of the thumb show calcification (arrow) and edema (open arrow) within the APB tendon/muscle. Steroid was injected using ultrasound guidance (F). Sesamoid bone (grey arrow)

Figure 9: A 55-year-old male with painful thumb abduction (A-F). Oblique radiograph (A) and reconstructed computed tomography–volume rendering technique image (B) of the thumb reveals subtle calcification along the lateral aspect of the base of proximal phalanx (arrow). Long axis (C) ultrasound of the thumb shows calcification (arrow) with heterogeneous hypoechoic area (open arrow) near the insertion of APB tendon.

Sesamoid bone (grey arrow)

Mentions: Calcific tendinitis of APB [Figure 9] is a rare entity[6] with patients presenting with pain along the radial aspect of the metacarpophalangeal joint. Ultrasound features of calcific tendinitis are thickening of the tendon, hyperechoic calcific foci and increased flow on color Doppler. Ultrasound guided steroid injection with needle decompression can be used to treat calcific tendinitis [Video 4].
