Posteromedial dislocation of the elbow: a case report

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Traumatology

Background:

• Elbow dislocations are common injuries, particularly in pediatric patients.
• Closed reduction is the initial treatment, but maintaining reduction can be challenging.
• Posteromedial dislocations present unique challenges in achieving stable reduction.

Discussion:

• The case highlights the importance of recognizing subtle anatomical features, such as the medial aspect of a posteromedial dislocation.
• Standard supination positioning failed to maintain reduction, indicating a need for alternative strategies.
• Adapting Rangs principles, originally for pediatric supracondylar humerus fractures, to elbow dislocations demonstrated success.

Key Insights:

• Forearm rotation is critical for maintaining elbow dislocation reduction.
• Pronation of the forearm is a key maneuver for stabilizing posteromedial elbow dislocations.
• Successful reduction and maintenance can be achieved by adapting existing orthopedic principles.

Outlook:

• Further studies are warranted to validate pronation as a standard technique for specific elbow dislocation types.
• This approach may reduce the need for surgical intervention in certain pediatric elbow dislocations.
• Refining reduction techniques based on dislocation patterns can improve patient outcomes.
