A new scoliotone, which is made up of screws, sockets, clamps, distraction rod and compression rod, was used stabilize immobilization of the spine in 10 cases. This scoliotone can produce free motion in three different levels, and has a strong power of fixation, distraction, compression and antitraction. In 10 cases when the patient's spinal curvature (cobb's angle) was less than 50 degrees, the average range of correction was 78.2% and the correction rate of kyphosis peak was 90%. When the spinal curvature was between 50 to 100 degrees, the average range of correction was 68.2%, and the correction rate of kyphosis peak was 87.7%. If the spinal curvature was more than 100 degrees, the average range of correction rate of kyphosis peak was 82%. After the operation, the patient might not be immobilized. In this paper, the biomechanical features of the vertebral arch, internal fixation and correction of kyphosis peak were discussed.
一种由螺钉、承窝、夹具、撑开杆和加压杆组成的新型脊柱侧弯矫治器,用于10例患者的脊柱稳定固定。该脊柱侧弯矫治器可在三个不同平面产生自由活动,且具有强大的固定、撑开、加压和对抗牵引能力。10例患者脊柱侧弯( Cobb角)小于50度时,平均矫正幅度为78.2%,后凸峰矫正率为90%。脊柱侧弯在50至100度之间时,平均矫正幅度为68.2%,后凸峰矫正率为87.7%。若脊柱侧弯大于100度,后凸峰平均矫正率为82%。术后患者无需固定。本文讨论了椎弓根的生物力学特征、内固定及后凸峰的矫正。
