We investigated 185 adolescents under the age of 19 years with spondylolysis. All but five were active in sport. The pars defect was classified into early, progressive and terminal stages. Of the 346 pars defects in 185 patients, 39.6% were early, 29.5% progressive and 30.9% in the terminal stages. Conservative management produced healing in 73.0% of the early, 38.5% of the progressive and none of the terminal defects. These results suggest that spondylolysis is caused by repetitive microtrauma during growth and can be successfully treated conservatively if treatment is started in the early stage. There was elongation of the pars interarticularis as the pars defect progressed, and this is likely to be a consequence of the defect rather than a contributing cause.
我们对185名19岁以下的椎弓根峡部裂青少年进行了调查。除5人外，其余均积极参加体育运动。将椎弓根缺损分为早期、进展期和终末期。在185例患者的346处椎弓根缺损中，39.6%为早期，29.5%为进展期，30.9%为终末期。保守治疗使73.0%的早期缺损、38.5%的进展期缺损愈合，而终末期缺损无一愈合。这些结果表明，椎弓根峡部裂是由生长过程中的重复性微创伤引起的，如果在早期开始治疗，可以成功地进行保守治疗。随着椎弓根缺损的进展，椎弓根间部出现延长，这可能是缺损的结果而非促成原因。
