Cubital tunnel syndrome (CuTS) is a common compression neuropathy of the ulnar nerve at the elbow. While the general anatomy and pathophysiology are well-documented, limited data exist regarding the anatomical dimensions of the cubital tunnel and their relationship to nerve stability. This study aims to investigate ulnar nerve compression and associate muscle using ultrasound B-mode imaging and shear wave elastography (SWE) to better understand the biomechanical changes under different arm positions.
