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.

Volar plate complex injury (A-E). Short axis ultrasound (A) and radiograph (B) shows obliquely rotated radial sesmoid (red arrow) with the normal ulnar sesmoid (open arrow). The radiograph also shows the radial sesmoid (red arrow) to be distally displaced at the level of the metacarpophalengeal joint. Magnetic resonance imaging shows the obliquely oriented radial sesmoid (red arrow) and normally oriented ulnar sesmoid (open arrow) on coronal T1 (C) and axial T2 (D) with increased signal in the volar plate and intersesmoidal ligament (yellow arrow) in axial PD fat sat image (E). (F - FPL, R - Right)

Figure 17: Volar plate complex injury (A-E). Short axis ultrasound (A) and radiograph (B) shows obliquely rotated radial sesmoid (red arrow) with the normal ulnar sesmoid (open arrow). The radiograph also shows the radial sesmoid (red arrow) to be distally displaced at the level of the metacarpophalengeal joint.

Mentions: Volar/plamer plate complex consists of the volar plate, which can be identified by pacing the probe along the long- and short-axis over the metacarpophalengeal [Figure 1E] and interphalengeal joints [Figure 1I] and can be seen as echogenic areas [Figure 1G and K]. Sesamoid bones and the interconnecting intersesamoidal ligament that form a part of the volar plate complex (at the level of the metacarpophalengeal joint) are seen embedded within the volar plate with the FPL traversing in between. The volar plate complex can be injured [Figure 17] by forced hyperextension of the metacarpophalengeal joint either with or without a bony fracture on the volar aspect of the base of the proximal phalanx and can be associated with ulnar collateral ligament injury.
