Sulcus Sign Test

Overview

• The sulcus sign is a clinical test used by healthcare professionals to assess the stability of the shoulder joint.
• It is often performed to diagnose shoulder instability or dislocation, particularly inferior glenohumeral instability.

Positive Test Indication

• A positive sulcus sign indicates potential shoulder instability.
• During the test, the examiner pulls the arm downward and observes the space between the acromion and the humeral head.
• A noticeable indentation or "sulcus" appears below the acromion if the test is positive.

Clinical Relevance

• A positive sulcus sign is commonly associated with:
  • Multidirectional instability
  • Inferior shoulder instability
  • Shoulder dislocations

Important Considerations

• Further evaluation may be required to determine the extent of instability and appropriate treatment.
• The test should be conducted by a trained professional to avoid unnecessary injury.

Treatment Implications

• Depending on the severity, treatment may range from physical therapy to surgical intervention.
• Focus on strengthening the shoulder muscles and improving joint stability.
