Spinal Instrumentation Plan & RecordFree

Leeds Spinal Instrumentation Plan and Record — v3.37.00-beta

A digital documentation tool for spinal surgery instrumentation. Records the pre-operative plan and post-operative construct, replacing hand-drawn diagrams with a structured, exportable format. Works in any modern browser on connected hospital computers, with a standalone offline version available for download.

Documentation tool — not a medical device. Not approved, cleared, or certified by MHRA, EU MDR notified bodies, or the FDA.

Population-based reference data from published literature is provided for convenience. The operating surgeon must verify all values against anatomy and imaging for each patient.

These tools are documentation and communication aids for surgical planning. They are not medical devices and have not been approved, cleared, or certified by any regulatory body, including MHRA (UK), notified bodies under EU MDR 2017/745, or the FDA.

Population-based reference data (screw sizes, pedicle dimensions, vertebral proportions) is drawn from published adult morphometry literature and represents group averages. Individual anatomy varies. The surgeon must verify all dimensions against the patient's own imaging. No reference data is provided for paediatric patients (under 14 years).

The operating surgeon bears full responsibility for all clinical decisions, including implant selection, placement, and verification at the point of use (WHO Surgical Safety Checklist). The surgical record is only as accurate as the information entered by the user.

All patient data remains on the local device. No data is transmitted to any server. There is no analytics, telemetry, or user tracking. Session Privacy is enabled by default — case data is not stored unless the user explicitly enables persistence. Users are responsible for data handling under their local regulations (e.g. UK GDPR, EU GDPR, HIPAA, Caldicott principles).
