Ultrasonographic study of the thumb pulleys and their entheses: correlations with anatomy and histology
Authors' conclusion
US is an effective and reliable tool to detect and study thumb pulleys, even though the identification of their entheses may be challenging and require advanced US skills.
Study context
- Population
- Cadaveric thumbs and thumbs from healthy controls240 thumb pulleys analysed
- Participants
- 20 vs 40
- Exposure
- Ultrasound (US) vs gross anatomy and histology of thumb pulleys and their entheses
- Cadaveric thumbsn = 20
- Healthy controls (HC)n = 40
- Outcome
- Characterisation of the thumb annular pulley system, including entheses, by anatomy, histology and US
