The Epidemiology and Demographics of Slipped Capital Femoral Epiphysis

Table 6

The age-weight or age-height test in children with SCFE is determined by graphically visualizing 6 groupings (or “cells”) of children with SCFE: cell 1, <10 years of age and ≥50th percentile in weight/height; cell 2, ≥10, ≤16 years of age and ≥50th percentile in weight/height; cell 3, >16 years of age and ≥50th percentile in weight/height; cell 4, <10 years of age and <50th percentile in weight/height; cell 5, ≥10, ≤16 years of age and <50th percentile in weight/height; and cell 6, >16 years of age and <50th percentile weight/height. Children in cells 3–6 (bold print) are considered to have a positive age-weight or age-height test; children in cells 1 and 2 (italic calligraphy) are considered to have a negative age-weight or age-height test.

Weight or height percentile	Age of patient with SCFE
	<10 years	10–16 years	>16 years
≥50th	Cell 1 (− test)	Cell 2 (− test)	CELL 3 (+ TEST)
<50th	CELL 4 (+ TEST)	CELL 5 (+ TEST)	CELL 6 (+ TEST)
