title: Prevalence of spondylolisthesis, transitional anomalies and low intercrestal line in a chiropractic patient population.
abstract: Five hundred and thirty radiographs were screened for the presence of certain lumbosacral anomalies. The prevalence of spondylolisthesis was found to be 5.1%, lumbarization 6.0%, sacralization 5.5% and low intercrestal line 56.9%. There was no greater prevalence in patients suffering from low back pain when compared against those who did not. There was a propensity for a low intercrestal line among females. Contrary to previous claims that lumbarization is more common in men, we found a moderate predilection for this finding among women. No difference between the two sexes was found in the prevalence of sacralization, contradicting previous claims that is more common in females, nor was spondylolisthesis found more frequently in men, contrary to our expectations.
