What is the primary purpose of the FADDIR test?

The FADDIR test, which stands for Flexion, Adduction, and Internal Rotation, is primarily used to assess anterior labral tears in the hip joint. The test is designed to provoke symptoms that may indicate damage to the labrum as well as the surrounding soft tissues, particularly in the anterior region of the hip. During the test, the clinician flexes the hip, adducts it, and internally rotates it, which places tension on the structures of the hip and can elicit pain if there are any abnormalities, such as a labral tear.

The biomechanics involved in the FADDIR test make it particularly effective for revealing issues associated with the anterior labrum, which is a common site for injuries in athletes and active individuals. By causing the hip to move in these specific directions, the test helps to identify potential pathology that may require further investigation or specific treatment.

In contrast, options related to measuring ranges of motion or evaluating hamstring lengths do not align with the primary intent of the FADDIR test, which is focused on the assessment of labral integrity. The functional assessment provided by this test is crucial for diagnosing hip-related pathologies, guiding the appropriate management and rehabilitation strategies.
