Resisted External Derotation Test

Source: Physiotutors

Execution

  1. 1Position the patient supine.
  2. 2Flex the test hip and knee to approximately 90 degrees.
  3. 3Passively place the hip into internal rotation.
  4. 4Ask the patient to externally rotate the hip back toward neutral while the examiner resists.
  5. 5Record whether lateral hip pain over the greater trochanter is reproduced.

Positive outcome

Reproduction of familiar lateral hip pain during resisted external derotation is positive. The test loads the gluteus medius / minimus tendons from a compressed and lengthened position. Deep buttock or groin pain should be interpreted differently.

Studies

StudyReliabilitySnSpLR+LR−
Lequesne et al. (2008)NA8897.332.60.12

CommentLequesne reported strong values in refractory greater trochanteric pain syndrome, but the sample was small and selected. Later gluteal tendinopathy work emphasizes combining palpation, loading, and compression tests rather than relying on one test. Despite the high LR+, this is graded moderate because of limited validation.
