Summary
Posterior shoulder dislocations are rare injuries often diagnosed late. Early detection and treatment, especially for isolated cases with small defects, lead to better outcomes.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Radiology
Background:
- Posterior shoulder dislocations and fracture-dislocations are uncommon injuries.
- They often result from seizures or high-energy trauma.
- Late diagnosis is frequent despite imaging advances.
Purpose of the Study:
- To review the diagnosis and treatment of posterior shoulder dislocations and fracture-dislocations.
- To identify factors influencing functional outcomes.
Main Methods:
- Review of literature on posterior shoulder dislocations and fracture-dislocations.
- Analysis of diagnostic facilitators and treatment options.
- Evaluation of prognostic factors for functional outcomes.
Main Results:
- Heightened clinical suspicion and appropriate radiography are key for detection.
- Treatment options range from closed reduction to arthroplasty.
- Early detection and treatment of isolated dislocations with small defects yield good outcomes.
Conclusions:
- Early diagnosis and treatment are crucial for favorable outcomes in posterior shoulder injuries.
- Prognosis is negatively impacted by late diagnosis, large humeral head defects, and associated fractures.
- Evidence-based treatment protocols are challenging due to injury rarity.
