The inter-and intraexaminer reliability of the Gonstead pelvic marking system

Abstract: An investigation was undertaken to determine the inter- and intraexaminer reliability of the Gonstead pelvic radiographic marking system. This methodology analyzes the relative dimensions and spatial positions of the two innominate bones and sacrum and measures leg length inequality through an evaluation of femur head height. Two examiners marked 71 full spine radiographs twice… Continue Reading »
