Boston Overlap Brace Size Chart Overview

This document provides a detailed size chart for the Boston Overlap Brace, including measurements and corresponding model numbers for both lined and unlined versions.

1. Measurement Specifications

• Hip circumference (cm): Ranges from 71 cm to 117 cm across sizes 1 to 10.
• Waist circumference (cm): Varies between 45 cm and 104 cm depending on size and variant (standard or 'D' variant).
• Xyphoid measurement (cm): Spans from 58.5 cm to 117 cm, indicating the vertical torso measurement relevant for brace fitting.

2. Size Variants

Each size has two variants:

• Standard size (e.g., 1, 2, 3, etc.)
• 'D' variant (e.g., 1D, 2D, 3D, etc.) which generally features different waist and xyphoid measurements, likely to accommodate different body shapes.

3. Model Numbering System

• Each size and variant corresponds to specific model numbers for lined and unlined braces.
• Model numbers for lined braces end with 'L' (e.g., 151L, 152L).
• Model numbers for unlined braces end with 'D' or 'DL' (e.g., 001D, 151DL).
• Model numbers are provided for two angles: 0 degrees and 15 degrees, indicating brace configuration or fitting angle.

4. Key Observations

• Hip, waist, and xyphoid measurements increase progressively with size.
• The 'D' variant sizes generally have smaller waist and xyphoid measurements compared to their standard counterparts, suggesting a different fit profile.
• Model numbers are systematically assigned to facilitate ordering and identification.

5. Usage Recommendations

Proper selection of brace size should be based on accurate measurement of hip, waist, and xyphoid dimensions. The choice between lined and unlined models and the angle configuration (0 or 15 degrees) should be made according to patient needs and comfort.
