Exploring the correlation between increased femoral anteversion and pars interarticularis defects in the lumbar spine: A single center experience

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.
