(tren'del-en-burg?)
Ger. surgeon, 1844–1924.

Trendelenburg gait

A side lurching of the trunk over the stance leg caused by weakness in the gluteus medius muscle.

Trendelenburg limp

An abnormal gait in which the patient transfers his or her weight laterally over the femoral head on the weight-bearing side and then shifts the weight back to a central position as the leg on that side is lifted from the ground. It is caused by weak hip adduction.

Trendelenburg position

A position in which the patient's head is low and the body and legs are on an elevated and inclined plane. This may be accomplished by having the patient lie flat on a bed and then elevating the foot of the bed. In this position, the abdominal organs are pushed up toward the chest by gravity. The foot of the bed may be elevated by resting it on blocks. This position is used in abdominal surgery. It is also usually used in treating shock, but if there is an associated head injury, the head should not be kept lower than the trunk. Synonym: head-down position See: position for illus

reverse Trendelenburg position

A body position in which the trunk and head are elevated above the pelvis and lower extremities.

Trendelenburg sign

A pelvic drop on the side of the elevated leg when the patient stands on one leg and lifts the other. It indicates weakness or instability of the gluteus medius muscle on the stance side.

Trendelenburg test

A test to evaluate the strength of the gluteus medius muscle. The examiner stands behind the patient and observes the pelvis as the patient stands on one leg and then the other. A positive result determines muscle weakness on the standing leg side when the pelvis tilts down on the opposite side.
