During the Thigh Thrust test in the Cluster of Laslett, what position is the hip flexed to?

• A. 45 degrees
• B. 90 degrees
• C. 120 degrees
• D. 75 degrees

Answer: (B)

The Thigh Thrust test, part of the Cluster of Laslett for assessing sacroiliac joint dysfunction, requires the hip to be flexed to 90 degrees. This specific position is crucial as it maximizes the load on the sacroiliac joint while allowing for proper engagement of the surrounding structures. When the hip is flexed to this angle, the examiner can apply a downward force through the femur, which can help elicit pain or reproduce symptoms related to sacroiliac joint dysfunction if it exists. Understanding this position is vital for accurate assessment and diagnosis in patients presenting with lower back or pelvic pain.
