脊柱失稳的因素及其对策（The factors and Countermeasures of spinal instability）

脊柱失稳的因素及其对策（The factors and Countermeasures of spinal instability） - on - spinal instability factors and Countermeasures Dong Fuhui (China orthopedics, Chinese Scientific Research Institute, Beijing 100700) key words spine; joint instability; instability and its means of for Spine management DONG Fu hui.Institute of Orthopaedics and Traumatology, ChinaAcademyofChinese Medical Sciences, Beijing 100700, ChinaKey words Spine; Joint instability; TherapyZhongguo Gushang/China J OrthopTrauma, 2008,21 (8): 563565 - 563 - China August 2008 twenty-first volume eighth issue China the J of OrthopTrauma, Aug.2008, Vol.21, No.8 The stability of the spine is a topic of great concern, and many theories, therapies and techniques emerge from it. Especially in recent years with minimally invasive surgery of spine continues to mature, high-tech materials to penetration of the biomedical field, surgery methods of spinal stability have been reported, it can be said that we ushered in an academic prosperity, technology diversity, All flowers bloom together. spinal surgery in new era. However, in the face of these popular technologies will require us to think about some problems calmly: built-in appliances and external support is able to provide much of the spinal stability? In spinal stability and noticed the corresponding function substitution and stress shielding failure? How to overcome the fatigue of materials and structures? If we strive to achieve the expected goal? In order to explore these issues, it is necessary to review the stability of spinal instability and related factors. 1 stability factors of the spine 1.1 the static stability of the spine The spinal column is maintained by the vertebral body, articular process, intervertebral disk, ligament and joint capsule. The elastic modulus of the above tissue is higher than that of muscle, and it has little deformation when subjected to external force, so it is also called the static stability system of spine. In recent years, ma
