Osterhoff G, et al. - A sum of 516 pelves were studied to analyze intrapelvic surface symmetry in reference to a preshaped suprapectineal acetabular implant in this cross-sectional study. They measured the distances between bone and the reference implant at 2310 reference points for each hemipelvis. They recorded 1.98 mm, the average distance between the left hemipelvis and the plate and 2.0 mm between the right hemipelvis and the plate. They observed no significant difference between the 2 hemipelvises (median absolute pairwise delta: 0.25 mm; 10% percentile: 0.04, 90% percentile: 0.82; Wilcoxon). Hence, they considered the pelvis sufficiently symmetric for using the mirrored contralateral hemipelvis as a template for patient-specific implants in acetabular fracture fixation with respect to the periacetabular surface of the inner pelvis.
