Does spinal morphology influence the occurrence of low back pain? A retrospective clinical, anthropometric, and radiological study.
OBJECTIVE
Insurance companies are showing considerable interest for measurement devices claimed to be effective in evaluating risks associated with occupational or sporting activities. The aim of this study was to evaluate the potential influence of spinal morphology on the risk of low back pain.


METHODS
1500 male construction work apprentices aged 16 to 23 years underwent spinal measurements at the Caen Teaching Hospital from 1991 to 1996. The 384 subjects with abnormal measurements or a history of spinal pain underwent plain radiography and a second set of spinal measurements done by a different examiner using a different device. The following radiological parameters were studied: incidence angle, junction couple, Ferguson's index, L1-L5 lordosis angle and L1-S1 lordosis angle.


RESULTS
In the 152 retrospectively studied subjects, no significant differences in static spinal parameters were found between subjects with and without a history of low back pain. The type of lordosis was correlated with the incidence angle but not with the junction couple.


CONCLUSIONS
In our population, spinal measurements were not correlated with a specific morphological pattern of the lumbar spine or pelvis, and neither was a history of low back pain correlated with a specific pattern of lumbar and pelvic balance.
