- This is the adult Short Arm Fracture Brace Open Thumb chart. Pediatric sizes are not included or mapped to this chart.
- The exact model's chart supplies circumference and length in inches. Its manufacturer-linked upper-extremity brochure explicitly lists the adult open-thumb model and describes Exos sizing as measurement around the hand, not around the wrist.
- The measurement location is stated as around the hand; a more specific anatomical landmark is not specified in the extracted source text and is not inferred here.
- The less-than symbols and boundaries are preserved exactly. XL circumference is published only as 11 inches, with no greater-than sign or upper limit; no range is invented.
- Length is reproduced as a source-listed dimension, not as an additional body-measurement instruction.
- The adult source lists XS, S, M, L and XL in left and right versions. These remain textual fit information, not separate variants.
