Needle Point Offset and Angle Offset for Cervical Pedicle Puncture Accuracy

124 Kirschner wire insertions were performed on nine bovine cervical spine models to validate a structured light navigation system. The dataset, authored by Xuanhuang Chen and last updated in May 2026, includes measurements of entry and exit point deviations, angle offsets, and registration accuracy. It was published on figshare under a CC-BY-4.0 license.

Use Cases

• Validate surgical navigation system accuracy based on reported root mean square and registration error metrics.
• Benchmark pedicle puncture precision using the reported entry and exit point deviation measurements.
• Analyze factors affecting puncture deviation based on the mention of bone surface influences.
• Train or test models for surgical instrument trajectory prediction using preoperative and postoperative coordinate data.

Strengths

• Reports a high puncture accuracy of 100% across 124 insertions.
• Provides specific quantitative error metrics, including an average entry point deviation of 0.904 mm and an exit point deviation of 1.253 mm.
• Includes registration accuracy data, reported as 0.01 ± 0.008 mm.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is derived from bovine spine models, which may not perfectly translate to human clinical applications.
