Abstract
Total hip arthroplasty (THA) preoperative planning requires the calibration of X-ray. We evaluate the magnification in standard pelvis hip X-ray and determine its relation with biometric factors. The magnification of 140 THA X-ray were calculated with the known femoral head (MF<sub>FH</sub>) and acetabular component (MF<sub>AC</sub>). Gender, age, height, weight, and BMI were correlated to the magnification. The MF<sub>FH</sub> and MF<sub>AC</sub> were 113.2 ± 4,4 and 113,4 ± 3,6 respectively. No significant differences by gender and no correlation with height, weight or BMI. The X-ray magnification should be calibrated in every institution to improve the accuracy of preoperative planning.
