Three-Dimensional Assessment of Bilateral Symmetry of the Scaphoid: An Anatomic Study

Table 1

Results of the left-to-right alignment differences of the distal poles represented by the six side-to-side differences based on the anatomical coordinate system. Negative displacement values represent opposite directions.

Displacement	Mean	Compared to 0 ( value)	SD
Translational
Ulnar (mm)	0.1	0.50	0.6
Dorsal (mm)	0.4	0.11	1.2
Distal (mm)	0.2	0.17	0.6
Rotational
Palmar rotation (deg.)	−1.1	0.32	4.9
Ulnar deviation (deg.)	−1.5	0.07	3.3
Pronation (deg.)	−1.0	0.27	3.7
