Finite Element Analysis and Comparative Study of 4 Kinds of Internal Fixation Systems for Anterior Cervical Discectomy and Fusion in Children

Table 2

The stress-strain range of 4 internal fixation systems in different motion states (, MPa).

Motion	ACOP	ACVLP	ACSLP	ACBLP
Ante flexion		^a	^a	^ab
Backward flexion		^a	^ab	^abc
Left flexion		^a	^ab	^ab
Right flexion		^a	^ab	^ab
Left rotation		^a	^ab	^abc
Right rotation		^a	^ab	^abc

Note: compared with the ACOP group, ^a; compared with the ACVLP group, ^b; and compared with the ACSLP group, ^c.
