[Determination of limb loading parameters on standard external fixators]

For the compression-traction osteosynthesis system CTS, the grounds for evaluating the existing parasitic deformity of loaded apparatus elements, such as pins and rings are shown. The measuring procedure for testing the axial and angular rigidity of a regenerate zone is presented. The angular rigidity is estimated by the ellipse of rigidities, i.e. by three parameters: a vector of the maximum rigidity (CU), a vector of the minimum rigidity (CV) and an azimuth of CU position in the ring plane. Some more useful functions of CTS, including the posthospital treatment of patients are described.
