Acetabular Posterior Column Screw Placement Data from CT and Cadaveric Imaging

50 CT scans from healthy adults and imaging from five cadaveric pelvises were used to evaluate screw placement in the acetabulum. The dataset, created by Hongtao Li and last updated in April 2026, contains measurements of anatomical angles and radiographic line relationships. It is a 15.2 KB Excel file shared under a CC-BY-4.0 license.

Use Cases

• Validate radiographic guidelines for posterior column screw placement based on measured anatomical angles.
• Train models to predict screw trajectory safety using angle and line relationship data.
• Compare the effectiveness of 45° versus α-degree obturator oblique views for intraoperative assessment.

Strengths

• Includes precise angle measurements (60.2 ± 2.5°) from 50 CT scans.
• Combines clinical CT data with controlled cadaveric imaging from five specimens.
• Dataset is openly licensed (CC-BY-4.0) for reuse and modification.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 15.2 KB size indicates a very limited scope, likely containing summary or measurement data only.
