Quantification of Contralateral Differences of the Scaphoid: A Comparison of Bone Geometry in Three Dimensions

Table 2

Contralateral differences of the 3D scaphoid geometry.

	Volume L, R diff (mm³)	Area L, R diff (mm²)	Length L, R diff (mm²)	Average surface deviation (mm)
Woman	87.4 (SD 74.7),; 10.2–235.1	30.2 (SD 21.9),; 1.6–67.2	0.6 (SD 0.5),; 0–1.4	0.22 (SD 0.04),; 0–1.84
Men	101.1 (SD 61.4),; 4.8–234.1	34.5 (SD 24.3),; 0.7–85	0.5 (SD 0.4),; 0–1.4	0.28 (SD 0.06),; 0–1.98
Both	95.3 (SD 66.2),; 4.8–235.1	32.7 (SD 22.9),; 0.7–85	0.2 (SD 0.4),; 0–1.4	0.26 (SD 0.2),; 0–1.98

Average contralateral difference, standard deviation (SD), and range in volume, surface area, and maximal length between the left (L) and right (R) scaphoids are given for woman (first row), men (second row), and for all subjects (third row).
