Summary

A rare case of median nerve entrapment after posterior elbow dislocation is detailed. This entrapment occurred at both a healed fracture site and within the elbow joint, suggesting a new classification.

Area of Science:

  • Orthopedic Surgery
  • Neurology
  • Traumatology

Background:

  • Elbow dislocations can lead to nerve injuries, but median nerve entrapment is uncommon.
  • Posterior elbow dislocations present unique challenges for neurovascular assessment.

Observation:

  • A patient presented with median nerve entrapment following a posterior elbow dislocation.
  • The entrapment was identified at two distinct sites: a healed medial epicondyle fracture and within the elbow joint itself.

Findings:

  • This case demonstrates dual-location median nerve entrapment (fracture site and joint) after elbow dislocation.
  • The median nerve was compressed both proximally at the fracture callus and distally within the joint capsule.

Implications:

Related Experiment Videos

  • The findings suggest a need to expand the classification of median nerve entrapment following elbow dislocations.
  • Recognizing dual-location entrapment is crucial for effective surgical management and improved patient outcomes.
  • This case highlights the importance of thorough intraoperative exploration in suspected nerve injuries post-dislocation.
