Q

The Trendelenburg test is a physical assessment for hip dysfunction that assesses hip abduction. What are the key muscles involved?

A
  • gluteus medius and minimus

- can see muscles contract to abduct the femur at the hip

44
Q

The Trendelenburg test is a physical assessment for hip dysfunction that assesses hip abduction, generally assessing gluteus minimus and medius. When we abduct the right femur at the hip, is it just the right sided gluteus minimus and medius that contract?

A
  • no
  • right side contract more for the abduction
  • BUT left side contracts pulling the hip laterally to stabilise the hip joint
45
Q

The Trendelenburg test is a physical assessment for hip dysfunction that assesses hip abduction, generally assessing gluteus minimus and medius. When we abduct the right femur at the hip like when we walk, the left hip abductors must stabilise the hip and stop the hip from dropping to the right (essentially try to rotate the left hip laterally). What happens in a positive trendelenburg test?

A
  • patient stands/walks and one side of the hip drops
  • if standing/walking on left leg, left sided weakness causes the right side of hip to drop as right side abduction cannot maintain hip stability
  • if standing/walking on right leg, left sided weakness causes the left side of hip to drop as left side abduction cannot maintain hip stability
46
Q

The Trendelenburg test is a physical assessment for hip dysfunction that assesses hip abduction, generally assessing gluteus minimus and medius. When we abduct the right femur at the hip like when we walk, the left hip abductors must stabilise the hip and stop the hip from dropping to the right (essentially try to rotate the left hip laterally).
