Pn. Vasudevan et al., CAN TRENDELENBURG SIGN BE POSITIVE IF THE HIP IS NORMAL, Journal of bone and joint surgery. British volume, 79B(3), 1997, pp. 462-466
In 1895 Trendelenburg described his sign to determine the integrity of
hip function. We found the sign to be positive in a patient whose hip
was clinically and radiologically normal, and therefore investigated
this in other patients. We confirmed that a medial shift of the mechan
ical axis of the leg below the hip may cause a positive Trendelenburg
sign, This has not been previously described.
