The use of a "prone push" posteroanterior radiograph of the spine was reviewed in 58 patients with scoliosis (82 curves) who underwent Harrington instrumentation and spinal fusion. The technique is previously undescribed and is accomplished by applying manual pressure to the apices of each curve with the patient prone on the X-ray table. The average correction obtained for all 82 curves was 21.1 degrees, as measured on the push films and 21.8 degrees postoperatively. The difference between these values was not statistically significant. The close relationship between push film and immediate postoperative correction was not altered by the location of the curve, the sex or age of the patient, the presence of a single- or double-major curve pattern, the type of instrumentation employed, nor the etiology of the scoliosis. This method is an alternative to the commonly employed supine lateral bending radiographs. An estimate of spinal flexibility is important for determination of structural change in the spine, the rigidity of curves considered for instrumentation, the curves requiring fusion, the length of fusion necessary, and the amount of correction that is safely possible.
对58例接受哈林顿器械植入和脊柱融合术的脊柱侧弯患者（82个弯曲）进行了脊柱后前位“俯卧推压”X线片使用情况的回顾。该技术此前未被描述，是通过让患者俯卧在X线检查台上，对每个弯曲的顶点施加手动压力来完成的。在推压片上测量，所有82个弯曲的平均矫正度数为21.1度，术后为21.8度。这些值之间的差异无统计学意义。推压片与术后即刻矫正之间的密切关系不受弯曲部位、患者性别或年龄、单主弯或双主弯模式的存在、所用器械类型以及脊柱侧弯病因的影响。该方法是常用的仰卧位侧弯X线片的替代方法。估计脊柱柔韧性对于确定脊柱的结构变化、考虑器械植入的弯曲的僵硬程度、需要融合的弯曲、所需融合的长度以及安全可行的矫正量很重要。
