Mennell sign

The Mennell sign (after James B. Mennell, English orthopedic surgeon, 1880–1957) is a clinical sign indicating inflammation or degenerative damage to the sacroiliac joint , as is the case with Bechterew's disease (ankylosing spondylitis) and other diseases from the group of Spondyloarthropathy is the case.

A distinction is made between the classic hyperextension test with positive Mennell signs and the 3-step test.

In the classic test, the doctor overextends the patient's extended leg to be examined (ipsilateral hyperextension), who is lying on the prone or on the side, in the sacroiliac joint with simultaneous pelvic fixation by pressure on the sacrum (on both sides in the prone position or on one side in the lateral position). If pain is indicated in the examined hip joint, it is referred to as a positive Mennell's sign. However, a negative sign does not rule out damage.

In the 3-stage test, the examination is differentiated according to the localization of the complaints in the facet joints of the hip joint (stage I), the sacroiliac joint (stage II) or the lumbar spine (stage III). The patient is placed on his stomach and the extended leg is raised. A fixation of the pelvis in the area of ​​the acetabulum (stage I), the sacrum (stage II) or the lumbar spine (stage III) is carried out by applying vertical pressure with the hand. A pain on the examined side is considered a positive sign.
