Objectives: After studying the article entitled “Identification of Aberrant Muscle Bellies in the Carpal Tunnel Using Sonography,” you will be able to:
Discuss the importance of identifying aberrant muscles in the carpal tunnel
Discover how to best identify an aberrant muscle in the carpal tunnel
Learn how to differentiate aberrant muscles from other pathologies
Carpal tunnel syndrome is compression of which structure at the level of the wrist? Median nerve Transverse carpal ligament Flexor digitorum superficialis muscle Median arteries
Aberrant muscles extending into the carpel tunnel typically have which appearance? Shortened and hypotrophic Shortened and hypertrophic Elongated and hypotrophic Elongated and hypertrophic
How can aberrant muscle bellies best be confirmed? Color Doppler Compression with transducer Dynamic movements Static scanning
Aberrant muscles within the carpel tunnel may be mistaken for which pathology? Bones of the wrist Blood vessels Solid masses Foreign bodies
The lumbrical muscles typically reside fully within which structure? Palm Carpal tunnel Proximal digits Distal forearm
