What is the Fortin Finger Test primarily used to assess?

• A. Lumbar spine involvement
• B. Hip joint osteoarthritis
• C. Sacroiliac joint involvement
• D. Quadriceps strength

Answer: (C)

The Fortin Finger Test is primarily used to assess sacroiliac joint involvement. This test is designed to evaluate whether pain or discomfort in the lower back or buttock region is related to the sacroiliac joint. During the test, the patient points to the area where they experience pain, usually in the vicinity of the sacroiliac joint. If the patient is able to accurately localize their pain to this specific area, it suggests that the sacroiliac joint may be the source of discomfort.

In contrast, lumbar spine involvement would not be specifically assessed with this test, as it focuses on the sacroiliac area. Hip joint osteoarthritis and quadriceps strength are also not evaluated through this test; other assessments and clinical evaluations are more appropriate for those conditions. Hence, the Fortin Finger Test's primary purpose is to pinpoint sacroiliac joint issues, making it an essential tool for clinicians when diagnosing lower back and pelvis-related pain.
