Fig. 3From: Short-term clinical and radiological results of two different design metaphyseal fitting femoral stems in total hip arthroplasty: a prospective, randomized trialAutoCAD template image on the AP pelvis radiograph showing subsidence calculation and the measurements of stem coronal alignment (angle between the longitudinal axis of the stem—green line, indicated on templates provided by the manufacturer, relative to the axis of the proximal femoral shaft—blue line). Radiographs were calibrated based on the known size of the femoral head. a Tri-Lock BPS. b Minima SBack to article page
