Radiographical magnification of the shoulder region

Popis výsledku v původním jazyce

Background Calibration of shoulder radiographs is required for accurate preoperative planning. Current practice mostly uses an empirical fixed calibration factor of 5%, and limited information is available about how the magnification of the glenohumeral region differs among patients. This retrospective observational study analyzed the patient-specific magnification factor in total shoulder arthroplasty. Methods Radiographs of 94 patients with unilateral total shoulder arthroplasty (SMR Reverse Shoulder System, Lima Ltd., San Daniele del Friuli, Italy) were obtained from archives. The reverse humeral body diameter was used as internal reference. The measured radiographical magnifications were correlated with the patients’ sex, weight, and height. Results The average magnification factor of the glenohumeral region was 11.9% (standard deviation: 3.2%, range: 5.7–20.3%). No statistically significant difference in radiographic magnification was found between the male and the female patients. The magnification factor was higher in patients with higher weight (p < 0.05), but the explanatory power of the model was weak (R = 0.09). Conclusions The observed radiographic magnification was considerably higher than a commonly used fixed calibration factor of 5% and exhibited considerable variability among the patients. Therefore, standard radiographs might not be appropriate for accurate preoperative templating, and we recommend using either computer tomography data or calibrating radiographs through external calibration markers for each patient.
