## What is SagittalMeter Lite?

SagittalMeter is an educative app to easily measure sagittal balance parameters, by directly placing your phone on the sagittal X-Rays.
  
The sagittal balance is an imperative factor to take into consideration for all practitioners treating spine problems and particularly for surgeons during the pre-operative phase. The compensatory mechanisms of a sagittal unbalanced spine may prevent a successful surgery outcome. A fundamental understanding of a correct sagittal alignment is strongly recommended in determining the correct use of fusion or non fusion devices. 
SagittalMeter enables you to measure 3 fundamental angles which are essential to analyze sagittal alignment:
    •    Pelvic incidence (PI)
    •    Pelvic tilt (PT)
    •    Sacral slope (SS)

## Key features

- Measure sagittal balance parameters
- Directly use phone on X-rays
- Calculate Pelvic Incidence (PI)
- Calculate Pelvic Tilt (PT)
- Calculate Sacral Slope (SS)
- Aid in spine problem analysis
