The transtrochanteric surgical approach to th e hip is commonly used, especially for revision hip surgery. Failure of greater trochanter osteotomy leads to hardware failure, persistent pain, and limp. The major cause of failure to heal is inadequate fixation of the greater trochanter. The objective of this study was to consider primary fixation characteristic by the tension of wire, pressure of cut surface of 2 fixation location. In this experiment, the model bone was used for the sample. As a result, when tension is the near 90 N, approximately 10 N decreased 60 minutes later. In addition, cut surface pressure decreases at greater trochanter top.
