Assessment of magnification of digital radiographs in total HIP arthroplasty

Objective: 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. Methods: The magnification of 140 THA X-ray were calculated with the known femoral head (MFFH...

Sumario:Objective: 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. Methods: The magnification of 140 THA X-ray were calculated with the known femoral head (MFFH ) and acetabular component (MFAC). Gender, age, height, weight, and BMI were correlated to the magnification. Results: The MFFH and MF(AC )were 113.2 +/- 4,4 and 113,4 +/- 3,6 respectively. No significant differences by gender and no correlation with height, weight or BMI. Conclusion: The X-ray magnification should be calibrated in every institution to improve the accuracy of preoperative planning.
