Cubital tunnel syndrome: anatomy, pathology, and imaging

Mohsin Hussein et al. Skeletal Radiol. 2025 Jan.

Abstract

Cubital tunnel syndrome (CuTS) is the second most common peripheral neuropathy in the upper limb. It occurs due to ulnar nerve compression within the fibro-osseous cubital tunnel at the elbow joint. Although CuTS is typically diagnosed clinically and with electrodiagnostic studies, the importance of imaging in evaluating the condition is growing. Knowing the typical imaging findings of ulnar nerve entrapment is necessary for precise diagnosis and proper treatment. In this article, we focus on the clinical features, workup and complex imaging of the "anatomic" cubital tunnel and relevant pathological entities.

Keywords: Anatomy; CuTS; Cubital tunnel; Entrapment; Pathology; Ulnar nerve.
