Ilizarov proposes the use of a special circular fixation device for treatment of bone defects and nonunions or for limb lengthening. Supposition was that the success of this method has to do with the specific mechanical behavior of the device. This behavior is a result of the configuration of the fixation elements. Therefore, a mechanical study of the sensitivity of the circular compression and distraction device (CDD) to configuration parameters was performed. The CDD was found to exhibit a nonlinear stiffness behavior, in particular under axial load. This may be favorable for the induction and tolerance of bone formation. Among the different parameters tested the ring radius was the most important with respect to stiffness. In general, the stiffness of the CDD allows adjustment during postoperative management. In magnitude, it is equal or lower when compared to other fixator types.
伊利扎罗夫提出使用一种特殊的环形固定装置来治疗骨缺损、骨不连或进行肢体延长。推测这种方法的成功与该装置的特定力学行为有关。这种行为是固定元件配置的结果。因此，对环形加压和牵张装置（CDD）对配置参数的敏感性进行了力学研究。发现CDD表现出非线性刚度行为，尤其是在轴向载荷下。这可能有利于骨形成的诱导和耐受。在所测试的不同参数中，环半径对刚度而言是最重要的。一般来说，CDD的刚度在术后管理期间是可以调节的。在数值上，与其他类型的固定器相比，它相等或更低。
