Summary
This case report details a rare irreducible elbow dislocation caused by a fall. The brachialis muscle and entrapped ulnar nerve complicated the open reduction surgery.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Anatomy
Background:
- Elbow dislocations are common injuries, but irreducible dislocations are rare.
- Post-traumatic irreducible elbow dislocations pose significant surgical challenges.
Observation:
- A patient sustained a lateral elbow dislocation from a fall onto a flexed elbow with medial forearm trauma.
- The injury mechanism involved forearm pronation.
Findings:
- Open reduction revealed the brachialis muscle formed a tight band obstructing joint reduction.
- The ulnar nerve was found entrapped within the dislocated joint.
Implications:
- This case highlights the importance of recognizing unusual entrapment patterns in irreducible elbow dislocations.
- Understanding the role of the brachialis muscle and ulnar nerve is crucial for successful surgical management of complex elbow trauma.
