# TLICS Calculator (Vaccaro 2005)

> TLICS Calculator (Vaccaro 2005) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Computes the Thoracolumbar Injury Classification and Severity Score (TLICS) from three caller-assigned clinical parameters: injury morphology, posterior ligamentous complex status, and neurologic status.

## Facts

- Endpoint: GET https://api.magentlab.com/api/calc/tlics
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/tlics-calculator-vaccaro-2005-c7e8e7be
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ksws_ZdWUYRalwOc2lKXf

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tlics-calculator-vaccaro-2005-c7e8e7be
```

Example prompt: Calculate the TLICS score for a patient with a burst fracture morphology, intact posterior ligamentous complex, and incomplete cord/conus neurologic injury — and tell me what the score means for operative vs nonoperative guidance.

## When to prefer this

Use this endpoint when you need a fast, programmatic TLICS score computation per the original Vaccaro 2005 methodology for thoracolumbar injuries. Prefer it over manual lookup tables when integrating TLICS into an automated clinical workflow or documentation tool. Do not use for neoplastic spinal instability (use SINS instead), cervical spine scoring, or AO Spine classification.

## Known failure modes

- Missing required query parameter (morphology, plc, or neuro) returns a validation error
- Invalid enum value for any parameter returns a 400 bad request
- Network timeout or API unavailability returns a 5xx error
- Score reflects only the Vaccaro 2005 TLICS system; not applicable to AO Spine, SINS (neoplastic), or pediatric variants

## How this service works

Vaccaro 2005 TLICS: morphology compression 1 / burst 2 / translational_rotational 3 / distraction 4 (single most severe) + plc intact 0 / suspected_indeterminate 2 / injured 3 + neuro intact 0 / nerve_root 2 / complete_cord_conus 2 / incomplete_cord_conus 3 / cauda_equina 3. Max 10. Bands 0-3 nonoperative, 4 equivocal, >=5 operative guidance. Not a surgical order. Not AO spine. Not SINS (neoplastic). magent does not read imaging. Not a medical device.

## Output

Returns the TLICS total score (0–10), individual subscores for morphology, PLC, and neurologic status, and the corresponding management guidance band: 0–3 nonoperative, 4 equivocal, 5 or above operative. Does not constitute a surgical order or diagnosis.
