In a roentgenographic analysis of the lumbar spine of 100 young female gymnasts engaged in high-level competition, the incidence of pars interarticular defects was 11 per cent; 6 per cent had spondylolisthesis. This is 4 times higher than their non-athletic female peers. It appears that the female athlete may have the same incidence of pars interarticularis defects as the male performing similar activities. Pars defects developing in association with athletic activities may be distinct from those developing in early childhood. A negative lumbosacral roentgenographic series does not completely rule out a developing pars defect. Bone scintography offers an additional tool for evaluating early stress reaction in the pars, and suggests that if the athlete restricts vigorous activity, some will heal without progressing to roentgenographically detectable defects. Low back pain in the young gymnast should be a warning sign. Close scrutiny of pars interarticularis in these young athletes will reveal a high incidence of developing defects.
在对100名参加高水平比赛的年轻女性体操运动员的腰椎进行的X线分析中，关节突间部缺损的发生率为11%；6%患有腰椎滑脱。这比她们不从事运动的女性同龄人高出4倍。似乎女性运动员关节突间部缺损的发生率可能与从事类似活动的男性相同。与体育活动相关的关节突缺损可能与儿童早期出现的缺损不同。腰骶部X线检查阴性并不能完全排除正在形成的关节突缺损。骨闪烁显像为评估关节突早期应力反应提供了一种额外的工具，并表明如果运动员限制剧烈活动，一些缺损将愈合而不会发展为X线可检测到的缺损。年轻体操运动员的腰痛应是一个警示信号。对这些年轻运动员的关节突间部进行仔细检查将发现正在形成的缺损的高发生率。
