Summary
Inferior glenohumeral dislocation, or luxatio erecta humeri, is a rare shoulder injury. Prompt recognition and reduction are crucial due to associated rotator cuff tears and neurovascular compromise.
Area of Science:
- Orthopedics
- Emergency Medicine
- Radiology
Background:
- Inferior glenohumeral dislocation (luxatio erecta humeri) is a rare shoulder injury.
- Often results from falls onto an abducted arm, potentially linked to syncopal episodes.
Observation:
- A 67-year-old woman presented with severe left shoulder pain and immobility after a fall.
- Physical examination revealed hyperabduction of the left arm (approx. 80 degrees).
- Radiographs confirmed inferior glenohumeral joint dislocation.
Findings:
- Successful closed reduction of the inferior glenohumeral dislocation was performed in the emergency department.
- This case highlights the importance of recognizing luxatio erecta humeri.
- High incidence of associated rotator cuff tears and potential neurovascular compromise noted.
Implications:
- Increased awareness is needed for timely diagnosis and treatment of inferior glenohumeral dislocation.
- Orthopedic consultation is vital due to the high risk of rotator cuff tears.
- Monitoring for and managing neurovascular compromise is essential, as neurological deficits often resolve post-reduction.
