Summary
Traumatic posterior glenohumeral joint dislocation is rare and often missed. Prompt diagnosis via history, exam, and radiography, followed by direct pressure reduction, is key for effective management.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Radiology
Background:
- Traumatic posterior glenohumeral joint (GHJ) dislocation is an uncommon injury.
- Subtle clinical presentations can lead to delayed or missed diagnosis.
- Early recognition is crucial for timely and effective treatment.
Purpose of the Study:
- To highlight the diagnostic challenges and management of traumatic posterior GHJ dislocations.
- To emphasize the importance of clinical suspicion and appropriate imaging.
- To describe a simple reduction technique.
Main Methods:
- Review of clinical presentation and diagnostic imaging findings.
- Description of the physical examination maneuvers for posterior GHJ dislocation.
- Explanation of the direct pressure reduction technique.
Main Results:
- Limitation in range of motion following acute trauma necessitates thorough evaluation.
- A 3-view plain radiography is essential for diagnosis.
- Direct pressure on the humeral head effectively reduces posterior dislocations.
Conclusions:
- Traumatic posterior GHJ dislocation requires high index of suspicion.
- Comprehensive assessment including history, physical exam, and radiography is vital.
- Direct pressure is an effective method for closed reduction.
