What type of injury might a positive Hibb Test suggest?

• A. Fractured femur
• B. Hip impingement
• C. Sacroiliac joint dysfunction
• D. Quadriceps strain

Answer: (C)

The Hibb Test is specifically designed to assess for dysfunction in the hip joint and the sacroiliac joint. A positive result indicates pain or restricted movement when the hip is internally rotated and flexed, which can be indicative of issues related to the sacroiliac joint. In cases of sacroiliac joint dysfunction, there often may be associated pain and altered mechanics that present during this test.

While the other options involve various types of injuries or conditions that could cause lower extremity pain, they do not specifically relate to the mechanics being tested by the Hibb Test. For instance, a fractured femur would typically present with more significant mobility limitations and deformity, while hip impingement more directly impacts the range of motion due to bony structures rather than the sacroiliac joint mechanics. Quadriceps strains primarily affect the muscle tissue and would not elicit symptoms based on the joint movement tested in the Hibb Test. Thus, the nature of the Hibb Test's focus on the hip and sacroiliac region aligns it most closely with dysfunction in that particular area.
