The characteristics of fresh lumbar spondylolysis at multiple levels were developed and compared with single-level spondylolysis.Fresh lumbar spondylolysis was diagnosed in 530 patients between March 2015 and March 2022.The subjects were divided into two groups: those with multiple-level spondylolysis (multiple group) and those with single-level spondylolysis (single group).The survey items included age, gender, time from pain awareness to consultation (disease duration), time from pain awareness to checkup (checkup duration), sports events, side of lamina, vertebral level, disease stage, and bone union rate.The number of patients in the multiple group was 44 (8.5%), and that of the single group was 486 (91.5%).Age was significantly higher in the multiple group (p＜0.01).No significant differences were observed between the two groups in terms of gender or disease duration or checkup duration.The rate of patients in athletics was 4.9%, the lowest of all sports events, in the multiple group. However, that of jumping event was high.The rate of bone union was 84.5% in the multiple group and 86.8% in the single group.The rate of bone union was not significantly different between the two groups.Multiple level spondylolysis was not a factor in inhibiting bone union.
