Unusual dislocations of the shoulder

Area of Science:

• Orthopedic Surgery
• Radiology
• Sports Medicine

Background:

• Erect (luxatio erecta) and superior glenohumeral dislocations are exceptionally rare shoulder injuries.
• Understanding their unique radiographic presentations is crucial for accurate diagnosis and management.

Observation:

• Luxatio erecta involves the humeral head positioned inferior to the glenoid, with the humeral shaft parallel to the scapular spine.
• Superior dislocations are characterized by the humeral head overlying the acromion or clavicle on anteroposterior radiographs.

Findings:

• The study analyzes radiographic findings in seven cases of erect and superior glenohumeral dislocations.
• Key radiographic features differentiating these dislocations from common anterior types are highlighted.

Implications:

• Accurate radiographic interpretation is essential for diagnosing these uncommon dislocations.
• Awareness of associated complications aids in comprehensive patient care and treatment planning.
