Trendelenburg Test

 Trendelenburg Test

What is Trendelenburg Test?

Trendelenburg Test is used to identify weakness of the hip abductors. It also can be used to assess other mechanical, neurological or spinal disorders, such as the Congenital dislocation of the hip or hip subluxation.

What does a positive Trendelenburg Test mean?

Several dysfunctions can produce a positive Trendelenburg Test:

  1. Weakness of gluteus medius muscle.
  2. Hip instability and subluxation.
  3. Hip osteoarthritis.
  4. Initially post Total Hip Replacement.
  5. Superior Gluteal Nerve Palsy.
  6. Lower back pain.
  7. Legg-Calvé-Perthes Disease.
  8. Congenital hip dislocation.

A Trendelenburg gait can also be observed caused by abductor insufficiency and is characterized by:

  1. Pelvic drop in swing phase.
  2. Trunk side flexion towards the stance limb.
  3. Hip adduction during stance phase.

Sensitivity & Specificity

A Systematic Review for diagnostic validity of the physical examination maneuvers for hip pathology, the Trendelenburg test demonstrated some evidence for use in a clinical setting in diagnosing gluteal tendon pathology:

Notes

Grading of the Trendelenburg test:

NegativePatient can lift the pelvis on the non–weight-bearing side
Weakly positivePatient can maintain the position of the pelvis on the non–weight bearing side but not lift it
PositivePelvis on the non–weight-bearing side drops visibly
