Description

In revision hip surgery, a transtrochanteric surgical procedure using a special designed trochanteric fixation device to make secure is widely accepted, even by orthopaedic surgeons who do not routinely divide the trochanter. However, optimal secured rate by the fixator was noted to be difficult, particularly in aged patients. The purpose of this study was to evaluate the optimally initial fixation with the device using the contact pressure distribution between the osteomized surfaces. It is shown from the experiments that careful preoperation planning to decide wiring location is an important factor in achieving a successful result.
