Equivalence of fusion rates after rigid internal fixation of the occiput to C-2 with or without C-1 instrumentation

Abstract

High fusion rates and low complication rates were achieved with each configuration examined. There was no difference in fusion rates between the group without (Group 1) and those with (Groups 2 and 3) C-1 instrumentation. These findings indicated that in the pediatric population, excellent occipitocervical fusion rates can be accomplished without directly instrumenting C-1.
