The lumbar spine was examined radiologically for the presence of spondylolysis and spondylolisthesis in 936 asymptomatic soldiers prior to military placement and in 662 soldiers complaining of low back pain. The overall incidence of spondylolysis was 9.7% in both groups, but bilateral spondylolysis was more prone to be associated with symptoms than a unilateral defect. In the symptomatic group the incidence of spondylolisthesis was 5.3% but only 2.2% in the asymptomatic group. The defect was seen in the oblique views only in 18.7% of the cases of spondylolysis. The precise diagnosis is important for vocational counselling and military placement.
对936名无症状士兵在入伍前以及662名抱怨下背痛的士兵进行了腰椎放射学检查，以确定是否存在椎弓根峡部裂和腰椎滑脱。两组中椎弓根峡部裂的总体发生率均为9.7%，但双侧椎弓根峡部裂比单侧缺损更容易出现症状。在有症状的组中，腰椎滑脱的发生率为5.3%，而在无症状组中仅为2.2%。仅在18.7%的椎弓根峡部裂病例中，在斜位片上可见缺损。准确的诊断对于职业咨询和入伍安排很重要。
