From: Model-based roentgen stereophotogrammetric analysis using elementary geometrical shape models: 10 years results of an uncemented acetabular cup component

Fig. 3

Calculated acetabular cup migration (a) along cranio-caudal direction [mm] and (b) about medio-lateral direction [deg] at six, 12 weeks, six, 12, 24, 60 and 120 months follow-up. The boxes represent 50% of included data (bound the 25th to 75th percentile) with the median (horizontal line), smallest and largest value (whisker bars) as well as outliers (circles) and extreme values (stars). Dotted horizontal lines indicate threshold for cranial (> 1.76 mm) acetabular cup migration according to Nieuwenhuijse et al. [24]
