The changes in the three-dimensional motion behavior of the lumbar motion segments, as affected by partial discectomy, are presented. The injured specimens, when subjected to flexion, extension, lateral bending, or axial torsional loads, showed significant increases in their major motions when compared with the corresponding intact specimen. No significant increases in the coupled motions were observed. These results suggest that it is better to excise as little of the nucleus as possible at surgery, since it may limit the increase in motion due to the injury.
本文展示了部分椎间盘切除术对腰椎运动节段三维运动行为的影响。与相应的完整标本相比，受损标本在进行前屈、后伸、侧弯或轴向扭转负荷时，其主要运动显著增加。未观察到耦合运动有显著增加。这些结果表明，手术时尽可能少地切除髓核较好，因为这可能会限制损伤导致的运动增加。
