The ST Spinal Trim measuring device is designed to help orthotists accurately define the finish trim lines for a custom full-time spinal scoliosis orthosis.

The system is specifically created to take the variables and inconsistencies out of the equation, streamlining the fitting process for you and your patients.

Utilizing an elastic waist band to maintain the location of the waist line, the adjustable and static measuring tools allow for accurate and consistent recording of all finish trim height measurements.

The Spinal Technology® Spinal Trim Measuring Device System

The system is made up of three items:

1. An elastic waist belt.

2. A ruled adjustable measuring tool with vertical sliding reference line indicators for capturing waist to pubis, pubis to xyphoid and waist to trochanter trim measurements.

3. A second ruled static measuring tool for capturing the trochanter to waist, waist to axilla and waist to inferior angle trim measurements.
