EXTERNAL FIXATION APPARATUS, HIGH TIBIAL OSTECTOMY APPARATUS, OSTECTOMY GUIDE DEVICE AND OSTECTOMY METHOD

摘要

PROBLEM TO BE SOLVED: To enable angulation and/or the control thereof in the external fixation apparatus used for ostectomy and other medical treatments. SOLUTION: The external fixation apparatus is provided with a stabilizing part 70 adapted to be externally coupled to an anterior portion of a tibial bone 122 and an angulation part 20 adapted to be externally coupled to another anterior portion of the tibial bone 122 while being coupled to the stabilizing part 70. The angulation part 20 is selectively adjustable to angulate a portion of tibial bone 122 about the axis of rotation offset from the longitudinal axis 142 of the tibial bone 122 following the ostectomical procesure on the tibial bone 122.
