Summary

This trial aims to determine which of two surgeries is more effective in treating ulnar neuropathy at the elbow and reducing symptoms.

Who is the study for?
This trial is for people with ulnar nerve entrapment at the elbow who have tried non-surgical treatments like night splinting. They must meet specific diagnostic criteria and be able to follow study procedures. It's not for those with previous elbow surgery, other neuropathies, or conditions that make surgery too risky.
What is being tested?
The study compares two surgeries: 'simple decompression' and 'subcutaneous anterior transposition,' to see which one better relieves symptoms of ulnar neuropathy at the elbow. Participants will be randomly assigned to one of these surgical options.
What are the potential side effects?
Potential side effects from both surgeries may include pain at the surgery site, infection risk, numbness or weakness in the hand or arm, and complications related to anesthesia.

Awards & Highlights

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.

Trial Design

2Treatment groups
Active Control
Group I: Subcutaneous anterior transpositionActive Control1 Intervention
Anterior transposition repositions the ulnar nerve, providing decompression and lengthening by moving the nerve anterior to the axis of elbow rotation
Group II: Simple decompressionActive Control1 Intervention
In-situ decompression releases only the compressive ligamentous structures overlying the ulnar nerve.

Other Research
The most common treatments for Ulnar Nerve Entrapment include decompression and transposition surgeries. Decompression involves relieving pressure on the ulnar nerve by removing any constrictive tissues or structures, which helps to restore normal nerve function and alleviate symptoms. Transposition surgery involves relocating the ulnar nerve to a position where it is less likely to be compressed or irritated, often moving it from behind the medial epicondyle to a more anterior position. These treatments are crucial for patients as they directly address the mechanical compression of the nerve, which is the primary cause of pain, numbness, and muscle weakness associated with Ulnar Nerve Entrapment. By alleviating this pressure, these surgical interventions can significantly improve nerve function and patient quality of life.
