Abstract

Introduction :
Cubital Tunnel Syndrome (CuTS) is the second most common compressive neuropathy of the upper limb, characterized by ulnar nerve entrapment at the elbow. Patients typically present with sensory disturbances (numbness, tingling in the fourth and fifth fingers) and motor deficits (weakness, muscle atrophy). When conservative treatments fail, surgical intervention becomes necessary to prevent irreversible nerve damage.

The two primary surgical approaches are *simple decompression* (releasing the nerve without repositioning) and *anterior submuscular transposition* (relocating the nerve anteriorly to reduce tension). While transposition was historically preferred for severe cases, recent studies suggest comparable efficacy for decompression in mild-to-moderate CuTS. However, debate persists regarding optimal technique selection, complication rates, and long-term outcomes.

This study prospectively compares these techniques in 30 patients, evaluating clinical improvement, electrophysiological recovery, and ultrasonographic changes. By analyzing postoperative outcomes, we aim to clarify the superiority of one method over the other, guiding surgical decision-making for CuTS management.
