ICC: intra-class correlation. Mean (mm): mean bone shortening in millimeters. SD crude: standard deviation of bone shortening in millimeters. SEM (mm): standard error of measurement in millimeters. MDC(mm): minimal detectable change in millimeters. For inter-rater analysis, the second measurement made by each rater was compared
