Trendelenburg Sign

Trendelenburg's sign is named after Friedrich Trendelenburg who was a German surgeon. This sign is positive in individuals whose abductor muscles of the hip, i.e. gluteus medius and gluteus minimus, have become weak or paralyzed. During test patient is advised to stand on one leg. Trendelenburg sign is considered positive if upon standing on one leg, the patient's pelvis tilts on the opposite side. The tilt on opposite side is caused by weakness of gluteus minimus and maximus muscles of opposite side of the stance leg. A positive Trendelenburg sign indicates muscular dysfunction, i.e. weakness of the gluteus minimus or medius. During Trendelenburg' test patient may complain of pain on opposite side.

Ortolani Test or Ortolani Maneuver

Ortolani Test includes Barlow Maneuver followed by Ortolani Maneuver. The test was described in 1937 and is named after Michael Ortolani. Barlow Maneuver is done first then Ortolani maneuver is performed. The test is performed to diagnosed congenital dysplasia of the hip joint. The Barlow Maneuver dislocates the hip joint and Oetolani maneuver reposition the hip joint by adjusting head of femur in hip joint socket.

Barlow maneuver- Examiner supports both leg with hand in flex position at knee joint. Then hip joint is also flex at 90 0. Examiner while continuing his hands on knee joint adduct the leg at hip joint while leg is pushed posteriorly toward the examining bed. Examiner may feel or hear click while hip joint is dislocated. This maneuver dislocates both or one hip joint.

Ortolani Maneuver- Ortolani Maneuver was described by Marino Ortolani. Following Barlow Maneuver Ortolani Maneuver is performed to reposition the head of femur in hip joint socket. The procedure is known as relocating a dislocated hip joint. The position of both knee and hip joint is maintained at 90 0 during entire period of test. The examiner repositions the hand to hold the leg. The examiner palpates the greater trochanter with index finger and also abducts the leg at hip joint using thumb. The maneuver places the head of femur into hip joint socket with a click sound. The test confirms the diagnosis of congenital hip joint dysplasia.

Gaenslen's Test

The test was described by Orthopedic Surgeon Dr. Frederick Gaenslen. Gaenslen's test is performed to diagnose cause of back pain. The positive test suggest cause of pain could be sacroiliac joint disease. The test is performed to stress both sacroiliac joint simultaneously. Patient is asked to lie on examination bed in supine position. As shown in image below, right leg is kept hanging on the side of the bed so right hip is optimally extended. Such position stretches right sacroiliac joint. Next patient is asked to flex knee joint. Now examiner will assist to flex the leg at hip joint. The attempt is made to touch the knee joint to abdomen. The maneuver will now stretch the left sacroiliac joint. The test is repeated on opposite side. The test is considered positive if patient is complaining of pain on one or both side. The cause of pain is sacroiliac joint arthritis or sprain. The test is also positive if patient is suffering with spondylo-arthritis or sciatica.

All these maneuvering test are subjective test and can be false positive or false negative. The positive test result has to be evaluated and compare by specialist and also supported by other findings of clinical or radiological examination. Test has to be performed by qualified physician, chiropractor or physical therapist.
