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.

Foreign body (thorn) in thumb (A-G). Patient photograph (A) shows the site of prick in the lateral aspect of the proximal thumb. Antero-posterior (B) and oblique (C) radiographs show the foreign body to be non-radio-opaque. Long (D and E) and short (F) axis ultrasound images show two hyperechoic foreign bodies (arrows) with surrounding hypervascular granulation tissue (open arrow in F). Long axis ultrasound (G) image shows granulation tissue/abscess (open arrow) tracking from the skin up to the foreign body (arrow)

Figure 21: Foreign body (thorn) in thumb (A-G). Patient photograph (A) shows the site of prick in the lateral aspect of the proximal thumb. Antero-posterior (B) and oblique (C) radiographs show the foreign body to be non-radio-opaque. Long (D and E) and short (F) axis ultrasound images show two hyperechoic foreign bodies (arrows) with surrounding hypervascular granulation tissue (open arrow in F). Long axis ultrasound (G) image shows granulation tissue/abscess (open arrow) tracking from the skin up to the foreign body (arrow)

Mentions: Traditionally, plain radiographs have been the first modality of choice for the diagnosis of foreign bodies. However, non-radiopaque foreign bodies in the soft tissue are difficult to localize on radiographs. For detection of superficial, nonradiopaque foreign bodies, ultrasound has been shown to be more effective than even computed tomography.[2425] Familiarity with the ultrasound appearances [Figure 21] of soft-tissue foreign bodies and a systematic evaluation of the region of interest in both the longitudinal and transverse orientations are needed for accurate assessment.
