Lewinnek tested whether measured acetabular cup orientation predicts dislocation after total hip replacement. Retrospective series of 300 total hip replacements with precise measurement of cup anteversion and lateral opening, comparing the 9 dislocated hips with stable hips and recording timing and prior surgery.
