Comparison of Biomechanical Performance of Five Different Treatment Approaches for Fixing Posterior Pelvic Ring Injury

Table 5

Comparison of the average resultant displacement at the sacroiliac joint for different fixation methods.

	TA1 (mm)	TA2 (mm)	TA3 (mm)	TA4 (mm)	TA5 (mm)
Tile B-ARI (R1)	3.1	1.8	1.6	2.3	1.5
Tile B-ARNF (R2)	3.2	1.9	1.7	2.4	1.6
Tile C-ARI (R3)	6.3	2.0	1.7	4.8	1.6
Tile C-ARNF (R4)	6.5	2.1	1.8	4.9	1.7

“TA1” represents treatment approach 1 for posterior pelvic ring injury, and so on; “ARI” and “ARNF” represent the fixation and nonfixation of the anterior pelvic ring and so on.
