Spine Orthopaedic Test: Yeoman's Test

Yeoman's Test is a physical examination test used to assess sacroiliac joint dysfunction or inflammation. Here are the steps to perform the test:

1. The patient lies prone (face down) on an examination table with one leg straight and the other flexed at the hip and knee.
2. The examiner stands on the side of the flexed leg and applies downward pressure just above the patient's knee joint.
3. The examiner then hyperextends the patient's knee and simultaneously places a firm pressure over the sacroiliac joint on the same side as the flexed leg.
4. The test is considered positive if the patient experiences pain in the sacroiliac joint region during the hyperextension maneuver.

A positive Yeoman's test suggests sacroiliac joint involvement, although the test is not always reliable and should be used in combination with other tests and clinical findings for a comprehensive evaluation.
