Special Tests

Special tests include those maneuvers used to define other sources of symptoms as well as those used to define symptoms localized to the hip. There also needs to be an appreciation of how tests for other sources may also affect a painful hip.

FIGURE 3.20. With the patient supine, the Patrick or Faber test is performed by crossing the ankle over the front of the contralateral knee and then forcing the knee of the involved extremity down on the table. This combination of flexion, abduction, and external rotation stresses the sacroiliac (SI) joint, and when injury or inflammation is present, this movement markedly enhances symptoms localized to the SI area. This same maneuver can irritate the hip joint as well, but with distinctly different localization of symptoms.

FIGURE 3.21. The log roll test is the single most specific test for hip pathology. With the patient supine (A), gently rolling the thigh internally (B) and externally (C) moves the articular surface of the femoral head in relation to the acetabulum but does not stress any of the surrounding extraarticular structures.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
