Superior Labrum Anterior Posterior Clinical Exam Techniques.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Diagnostic Imaging

Background:

• Superior Labrum Anterior Posterior (SLAP) lesions are common in athletes and older adults.
• Accurate diagnosis aids in improving athletes' return to play and overall quality of life.
• Clinical examination is a key component for early and precise SLAP lesion detection.

Purpose of the Study:

• To provide a centralized resource for clinicians on performing SLAP lesion diagnostic examinations.
• To detail the attributes and statistical measures of various clinical tests for SLAP lesions.
• To enhance the diagnostic capabilities of healthcare professionals through accessible educational content.

Main Methods:

• Demonstration of seven distinct clinical tests for SLAP lesions: modified dynamic labral shear (DLS) test, Speed's test, O'Brien test, anterior slide test, crank test, Kim test, and Jerk test.
• Explanation of the procedural steps for each examination.
• Presentation of relevant statistical data, including sensitivity and specificity for each test.

Main Results:

• The modified dynamic labral shear test (72% sensitivity, 98% specificity) and Kim test (61%-92% sensitivity, 88%-99% specificity) exhibit high sensitivity and specificity.
• The anterior slide test (81%-89% specificity) and Jerk test (94%-99% specificity) are also highly specific.
• Statistical measures vary, making certain tests more effective for ruling in or ruling out SLAP lesions.

Conclusions:

• The modified dynamic labral shear test and Kim test are most valuable for ruling out SLAP lesions due to their high sensitivity.
• The modified dynamic labral shear test, Kim test, anterior slide test, and Jerk test are effective for ruling in SLAP lesions due to high specificity.
• Clinician comfort and proficiency in performing specific tests are critical for accurate in-clinic diagnosis of SLAP lesions.
