What is the main indication for using the Cluster of Laslett?

• A. Hip dislocation
• B. SI inflammation, subluxation, or sprain
• C. Knee osteoarthritis
• D. Thigh muscle strains

Answer: (B)

The Cluster of Laslett is primarily used to assess conditions related to the sacroiliac (SI) joint, specifically focusing on identifying SI inflammation, subluxation, or sprain. The cluster consists of several diagnostic tests that help clinicians determine whether the SI joint is the source of a patient's pain. These tests include the distraction test, compression test, and other maneuvers designed to provoke pain specific to the SI joint anatomy and function.

When appropriately applied, the Cluster of Laslett aids healthcare professionals in establishing a diagnosis that can inform treatment options for patients with lower back pain or lower extremity issues that may stem from SI dysfunction. It is crucial in effectively isolating the specific source of pain, thereby supporting targeted management strategies. This targeted approach is not applicable to hip dislocation, knee osteoarthritis, or thigh muscle strains, as those conditions involve different anatomical structures and require distinct assessment protocols.
