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.

Probe positions and ultrasound for evaluation of thenar muscles, FPL and extensor compartment tendons of the thumb (A-I). Probe position in short (A) and long (B) axis with corresponding ultrasound image (C and D) of thenar muscles and the flexor pollicis longus. Schematic diagram (E), probe position (F), and ultrasound image (G) shows Lister's tubercle, EPL and 2nd compartment tendons. Probe position (H) and ultrasound image (I) shows the 1st compartment tendons. (FPL- F, metacarpal - M, dorsal interossei – D, Lister's Tubercle - L, 1st compartment - 1, 2nd compartment - 2, 3rd compartment tendons - 3)

Figure 3: Probe positions and ultrasound for evaluation of thenar muscles, FPL and extensor compartment tendons of the thumb (A-I). Probe position in short (A) and long (B) axis with corresponding ultrasound image (C and D) of thenar muscles and the flexor pollicis longus. Schematic diagram (E), probe position (F), and ultrasound image (G) shows Lister's tubercle, EPL and 2nd compartment tendons. Probe position (H) and ultrasound image (I) shows the 1st compartment tendons. (FPL- F, metacarpal - M, dorsal interossei – D, Lister's Tubercle - L, 1st compartment - 1, 2nd compartment - 2, 3rd compartment tendons - 3)

Mentions: Flexor pollicis longus (FPL) is seen on the palmar surface of the wrist and can be located at two levels in the transverse probe position at proximal and distal carpal tunnel by locating scaphoid tubercle and pisiform (proximal level) and trapezium and hook of hamate (distal level). FPL tendon is seen just medial to the scaphoid tubercle and trapezium. The FPL is then evaluated in the thenar eminence in long and short axis with the hand in supinated position [Figure 3A–D] along with the thenar muscles. Moving the thumb can be helpful in identifying the tendon.
