  • The terms contralateral and ipsilateral refer to the direction of version with respect to the operated side. The term “inconsistent” refers to patients in whom head version occurred sometimes ipsilateral and sometimes contralateral to the operated side. When comparing contralateral head version with the rest, there is a very significant association between contralateral head version and poor outcome and between lack of contralateral head version and favourable outcome (contingency table 1, 9, 19, 8, Fisher’s exact test, two tailed, p= 0.002).
