Abstract

Cubital tunnel syndrome (CuTS) is a prevalent but often under-recognized compressive neuropathy of the upper extremities, involving the entrapment of the ulnar nerve within the cubital tunnel at the elbow. CuTS is common, but remains relatively unfamiliar to many neurosurgeons compared to other neuropathies. It frequently presents with sensory disturbances and motor deficits in the hand, particularly affecting the ulnar digits, and it may be linked to specific usage patterns or even considered a form of neurotrauma. Its diagnosis typically involves a clinical assessment supplemented by imaging and electrophysiological studies to evaluate the extent of nerve involvement. While conservative management may be sufficient in the early stages, surgical intervention is often necessary for advanced cases, and various techniques offer differing outcomes. This review underscores the importance of a thorough anatomical understanding in guiding an accurate diagnosis and effective treatment, ultimately contributing to improved patient outcomes. These insights are essential for clinicians encountering the complexities of CuTS in diverse clinical scenarios.
