Characterization of digital annular pulleys and their entheses: an ultrasonographic study with anatomical and histological correlations
Authors' conclusion
US is an effective tool to detect and study DAPs. DAP entheses reveal both fibrous and fibrocartilaginous characteristics. A newly described manoeuvre to optimize DAP enthesis visualization enhances their detection by US.
Study context
- Population
- Cadaveric hands and healthy controls; digital annular pulleys and their enthesesDigital annular pulleys (DAPs) analysed (400 cadaveric, 800 healthy controls (HCs))
- Participants
- 1,200 participants
- Comparison
- US vs gross anatomy dissection for digital annular pulleys
- Cadaveric handsn = 20
- HCsn = 20
- Outcome
- Characterization of DAPs by anatomy, histology and US, focusing on detection and description of pulley entheses
