Objective: To determine the most relevant method of measurement of the radiographic hip joint space width (JSW).Design: Seventy hips were examined from 36 patients of the ECHODIAH study having had one to four X-rays of the pelvis during the 3-year course of the study. Minimum interbone distance (MIDc), mean width of both the whole joint space (MJSWL) and a region of interest of the joint space (MJSWroi) were measured using computerized analysis of digitized radiographs. MID was also measured using a graduated eyepiece (MIDge). Reproducibility of the measurement was assessed by the intraclass coefficient of correlation. Sensitivity to change was evaluated by the standardized response mean.Results: The intraobserver intraclass coefficient of correlation of MIDc and MJSWroi was 0.98 and 0.94, respectively The mean value +/-S.D. of MJSWL, MJSWroi, MIDc and MIDge was 3.3 +/-0.9, 2.6 +/-0.9, 2.4 +/-0.9 and 2.6 +/-1.2 mm, respectively. MIDge was significantly larger than MIDc (mean difference: 0.21 +/-0.62 mm, P
