The cn/cn dwarf mouse. Histomorphometric, ultrastructural, and radiographic study in mutants corresponding to human acromesomelic dysplasia Maroteaux type (AMDM)

Table 2 **Linear Measurements (in millimeters) from radiographs* at 5 weeks of age to assess length ratios**

	cn/cn	cn/cn+	Measurements	Mean length ratio
Iliac crest to distal tip of ischium	11.1 (11.0-11.3)	16.8 (16.3-17.2)	8 per group	0.66
Radius Length				0.53
Ulna Length				0.59
Comparable metacarpal/metatarsal bones and phalanges (forelimb and hindlimb)				0.67

*measurements from radiographs accurate for determining length ratios but not actual lengths.
