Early complications of primary shoulder dislocations

Area of Science:

• Orthopedics
• Neurology
• Sports Medicine

Background:

• Primary shoulder dislocation is a common injury.
• Complications can significantly impact patient outcomes and recovery.
• Understanding risk factors is crucial for prevention and management.

Purpose of the Study:

• To prospectively evaluate the incidence and types of complications following primary shoulder dislocation.
• To identify patient demographics and injury characteristics associated with increased complication rates.

Main Methods:

• Prospective study conducted over three years (1973-1976).
• Clinical examinations performed in Casualty and Physical Medicine departments.
• Evaluation focused on rotator cuff, neurovascular status, and extremity function.

Main Results:

• 26% of 238 patients experienced complications.
• Common complications included brachial plexus lesions (29), axillary nerve lesions (21), and rotator cuff ruptures (28).
• Complications were more frequent in patients over 50, manual laborers, and those with delayed humerus reduction (>12 hours).

Conclusions:

• Primary shoulder dislocation carries a significant risk of complications, particularly neurovascular and rotator cuff injuries.
• Older age, manual labor, and prolonged dislocation are associated with higher complication rates.
• Early reduction and careful patient selection may mitigate risks.
