The mechanical effectiveness of applying transverse forces by segmental spinal instrumentation to correct scoliosis is examined in this paper. Comparisons with traditional Harrington instrumentation are made on the basis of each method's potential to produce corrective bending moments and their ability to transfer this correction to the spine. Recognizing the scoliosis is a three-dimensional deformity, biomechanical evaluations are performed in each of the three anatomic planes, with special attention paid to maintaining normal sagittal plane contour and transverse plane derotation. Such an analysis indicates that segmental spinal instrumentation has a clear mechanical advantage over traditional Harrington instrumentation in providing and maintaining correction. Proposed improvements include the development of instrumentation which can be segmentally attached to the vertebra without invading the spinal canal.
本文研究了通过节段性脊柱内固定施加横向力来矫正脊柱侧弯的力学有效性。基于每种方法产生矫正弯矩的潜力及其将这种矫正传递到脊柱的能力，与传统的哈灵顿内固定进行了比较。认识到脊柱侧弯是一种三维畸形，在三个解剖平面中的每一个平面上都进行了生物力学评估，特别注意保持正常的矢状面轮廓和横断面去旋转。这样的分析表明，在提供和维持矫正方面，节段性脊柱内固定比传统的哈灵顿内固定具有明显的力学优势。提出的改进措施包括开发一种可以节段性地附着在椎体上而不侵入椎管的内固定器械。
