Intraosseous Nontraumatic Median Nerve Entrapment at the Elbow: A Case Report

Area of Science:

• Orthopedic Surgery
• Neurology
• Anatomy

Background:

• Intraosseous median nerve entrapment typically occurs after elbow trauma like fractures or dislocations.
• This condition is considered rare and severe, affecting nerve function within the bone.

Observation:

• A unique case of median nerve entrapment was identified within the distal humerus.
• The entrapment was observed to be atraumatic, meaning it did not result from injury.

Findings:

• This represents the first reported instance of atraumatic intraosseous median nerve entrapment.
• The median nerve was found to be compressed inside the humerus without any history of trauma.

Implications:

• This finding expands the known spectrum of median nerve entrapment etiologies.
• Further research may be needed to understand the mechanisms and diagnostic approaches for atraumatic intraosseous nerve entrapment.
