While an increased incidence of scoliosis in symptomatic spondylolysis and spondylolisthesis has been established previously, a comparison of its occurrence in symptomatic and asymptomatic individuals has not been performed. The present study is a comparison of symptomatic and asymptomatic young men with analysis as to the incidence of scoliosis. Idiopathic scoliosis was not found and all cases were due to spasm scoliosis or olisthetic scoliosis with the spasm type being much more common. Scoliotic curves were divided into mild (0-9 degrees) and moderate (10-20 degrees). No case of a curve greater than 20 degrees was seen. Scoliosis incidence in asymptomatic individuals without a pars break was 6.65%. In the groups of: (1) asymptomatic unilateral spondylolysis, (2) asymptomatic bilateral spondylolysis, (3) symptomatic bilateral spondylolysis, and (4) asymptomatic spondylolisthesis the scoliosis incidence was similar, ranging from 13.3-23.8%. These figures are significantly higher than those seen in the asymptomatic subjects without a pars break, but they are in the same range as in symptomatic patients without a pars break, suggesting that muscle spasm is the principal cause of the scoliosis.
虽然先前已证实有症状的椎弓根峡部裂和椎体滑脱患者中脊柱侧弯的发生率增加，但尚未对有症状和无症状个体中脊柱侧弯的发生率进行比较。本研究对有症状和无症状的年轻男性进行了比较，并分析了脊柱侧弯的发生率。未发现特发性脊柱侧弯，所有病例均为痉挛性脊柱侧弯或滑脱性脊柱侧弯，其中痉挛型更为常见。脊柱侧弯曲线分为轻度（0-9度）和中度（10-20度）。未发现大于20度的曲线病例。无椎弓根断裂的无症状个体中脊柱侧弯的发生率为6.65%。在以下几组中：（1）无症状单侧椎弓根峡部裂，（2）无症状双侧椎弓根峡部裂，（3）有症状双侧椎弓根峡部裂，以及（4）无症状椎体滑脱，脊柱侧弯的发生率相似，范围为13.3%-23.8%。这些数字明显高于无椎弓根断裂的无症状受试者，但与无椎弓根断裂的有症状患者处于同一范围，提示肌肉痉挛是脊柱侧弯的主要原因。
