Table 1.

Evaluation of target reduction (and healthy subjects) by an orthopaedic trauma surgeon. The top row (experimental/dislocated) shows the surgeon’s assessment of dislocation severity. The second row (experimental/reduced) shows the surgeon’s assessment after reduction by an amount estimated by the proposed method, which was found to agree with the third row (control), which shows the surgeon’s assessment of dislocation in natural, healthy (non-dislocated) pelves.

Group		Healthy	Mild	Moderate	Severe
Experimental	Dislocated	0	2	2	2
	Reduced	5	1	0	0
Control		5	1	0	0
