Introduction:
Altered femoral version can result in lumbar hyperlordosis and hip spine syndrome. We conducted a retrosepctive study to evalute if there is correlation between altered femoral version and pars defect.
Materal And Methods:
A cohort of pateints with CT rotational profile and MR of lumbar spine over a 12 year period were included in the sutdy. The femoral version was calculated and the MR was evaluated for pars defect.
Results:
130 patients had CT rotational profile and MR of lumbar spine with a female predomiannce (94 female and 36 males) and average age of 24.3 years. There were 6 patients with bilateral pars defects involving L5 (3 with increased femoral version, 2 with decreased version and one had normal version).
Conclusion:
Increased femoral anterversion is not associated with increased prevalence of pars defects.
