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.
Pedicle screws, hooks & fixation
Interbody cages (ACDF to ALIF) and disc replacement (cervical ACDR + lumbar TDR / arthroplasty)
Schwab osteotomy classification
Deformity correction forces
Level-specific trajectories (pedicle, lateral mass, cortical, translaminar, pars, transarticular)
Screw shank PA projection visualisation
Multi-system implant support (up to 5)
16 manufacturers, 98 systems with kit validation
Modular barcode/UDI scanning (shank, head, set screw, blocker)
Cage and rod barcode scanning with auto-fill (approach, dimensions, material, length)
Reconstruction cage (VBR) scanning for corpectomy â VLIFT, Capri, FORTIFY with inline accessory (endcap, bone screw) scan rows
Multi-level corpectomy on chart (1â4 vertebrae) â endplate-to-endplate cage with end-caps; resected bodies render as dashed outlines
Unified scan surface (camera, wedge, manual typing) inside every implant modal
Wrong-component scans soft-route to the case scan pool â no work lost
Case-level scan pool (bulk-scan set screws, allocate to levels later; HIBC + GS1)
87,113 implant barcodes in offline catalogue across 134 systems (including 8 cervical artificial disc brands; lumbar TDR scans resolve via openFDA online lookup pending v3.19.01 GUDID harvest)
Per-component lot & expiry traceability
Clinical attribute badges on every scan (cannulated, fenestrated, augmentable, cortical, MIS, long vs short blade)
HIBC Code 128 support (Stryker spine) in addition to GS1-128 and GS1 DataMatrix
Sex-specific screw size ranges (population morphometry)
Standard vs specialist screw sizes â picker defaults to manufacturer STG ordering matrix; specialist GUDID-only sizes still scan and round-trip
Catalogue warnings for out-of-system screws
Structured rod data & linked lengths
Auto-generated inventory by screw system
Record locking (Finalise & Lock Record) with clear feedback when edits are attempted on a locked record
Patient age auto-derived from DOB and surgery date
Undo / Redo on every form factor (toolbar buttons + keyboard chord)
Trust this device preference
PDF (A4 300 DPI), JPG & JSON export
22 languages (incl. CJK & RTL)
QR code sharing (show, scan, load from image)

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).
