摘要
In total hip replacement, orientation of the cup is critical to the stability of the prosthesis. A new method to determine the angle of planar anteversion is described. A simple mathematical formula uses the measurements taken from anteroposterior radiographs to calculate the planar anteversion without reference to tables or charts. An experimental study in vitro has shown the efficacy of the formula in giving results which are within a clinically acceptable range.
