The authors examine interfacet distance (IFD), facet joint orientation (FJO), and lumbar segmental lordosis (LSL) all together on the basis of lumbar computed tomography (CT) scan of 35 patients with L5 spondylolysis and 36 unaffected control groups. Thirty\u2010five Korean military recruits, aged 19\u201323 (mean 20.9 years), were diagnosed as L5 spondylolysis by lumber CT scans. As a control group, 36 male Korean military recruits, aged 18\u201325 (mean 21.3 years), were reconfirmed as not affected by lumbar spondylolysis by CT scan when they visited our hospital complaining of back pain. This study compares IFD, FJO, and LSL for each lumbar segment between the spondylolytic and unaffected groups. We also propose the use of normal mean data of IFD, FJO, and LSL of lumbar vertebrae from 36 Korean young military recruits because each measurement has power as an absolute value, like data from an osteologic collection in other studies. Comparison of IFD between spondylolytic and unaffected individuals reveals significant differences at the L3, L4, and L5 level (<jats:italic>P<\/jats:italic> = 0.0384, <jats:italic>P<\/jats:italic> = 0.0219, and <jats:italic>P<\/jats:italic> &lt; 0.0001, respectively). In the group of spondylolysis, the increase of IFD from L4 to S1 was less pronounced (<jats:italic>P<\/jats:italic> &lt; 0.0001) and the LSL at L5\u2010S1 was more lordotic (<jats:italic>P<\/jats:italic> = 0.0203). Interfacet distance and lumbar lordosis were significantly different between patients with L5 spondylolysis and individuals without pars defect on L5. In the spondylolysis group, and the increase of IFD from L4 to S1 was less pronounced and the LSL at L5\u2010S1 was more lordotic. Clin.
