The inferior sacral iliac line as a horizontal reference plane in paediatric pelvic radiographs.
Background: While often used, Hilgenreiner's line may not always be a reliable reference plane following triple innominate pelvic osteotomy or trauma to the triradiate cartilage. The inferior sacral-iliac line is a horizontal line connecting the sclerotic corners of the inferior sacral-iliac joints. This is a consistent landmark in the ossifying infant pelvis as well as the fully developed adult pelvis. The goal of this study was to determine if there is a difference in measurements between the inferior sacral-iliac line and Hilgenreiner's line in order to identify an alternative horizontal reference plane.
Methods: 3 reviewers (fellowship-trained paediatric orthopaedic surgeon, junior orthopaedic resident, senior orthopaedic resident) reviewed 100 paediatric non-osteotomized pelvises. The difference between Hilgenreiner's line and the inferior sacral-iliac line were measured and reported. Measurements were repeated a minimum of 48 hours apart, resulting in 600 comparisons between Hilgenreiner's line and the inferior sacral-iliac line. The standard error of measurement was calculated to assess the variation in measurements between each individual observer and the group as a whole.
Results: The mean standard error of measurement between Hilgenreiner's line and the inferior sacral-iliac line was 0.44° (95% CI, ± 0.86). Reviewers 1-3 demonstrated a mean standard error of measurement of 0.38, 0.28, and 0.35 (95% CI, ± 0.74, 0.55, and 0.86) respectively. There was no statistically significant difference between reviewers (p > 0.05). Intra-observer reliability for reviewers 1, 2, and 3 was 0.64 (0.47-0.76), 0.75 (0.63-0.83), and 0.54 (0.32-0.69) respectively, with an inter-observer reliability of 0.42 (0.20-0.60) degrees.
Conclusions: In this proof-of-concept study, the inferior sacral-iliac line was found to be an appropriate alternative to Hilgenreiner's line that is easily identifiable for all levels of orthopaedic training. Future inferior sacral-iliac line studies should demonstrate the reliability of multiple acetabular measurements, both pre- and post-osteotomy.
期刊介绍:
HIP International is the official journal of the European Hip Society. It is the only international, peer-reviewed, bi-monthly journal dedicated to diseases of the hip. HIP International considers contributions relating to hip surgery, traumatology of the hip, prosthetic surgery, biomechanics, and basic sciences relating to the hip. HIP International invites reviews from leading specialists with the aim of informing its readers of current evidence-based best practice.
The journal also publishes supplements containing proceedings of symposia, special meetings or articles of special educational merit.
HIP International is divided into six independent sections led by editors of the highest scientific merit. These sections are:
• Biomaterials
• Biomechanics
• Conservative Hip Surgery
• Paediatrics
• Primary and Revision Hip Arthroplasty
• Traumatology
