摘要

The extended femoral trochanteric osteotomy allows excellent exposure of the proximal femoral canal, which facilitates resection of the canal's contents during revision total hip arthroplasty. Once the proximal femoral canal has been evacuated and a new femoral component has been placed, the osteotomy should be fixed in proper position to allow healing. The purpose of our study was to compare the fixation of an extended trochanteric osteotomy using 2 vs 3 braided cables with regard to stiffness, peak force, axial displacement, transverse displacement, and angular displacement using an in vitro biomechanical model. Nine paired cadaver femurs were loaded to failure. Movement at the osteotomy site before failure was recorded using a motion analysis system. There was no statistically significant difference between 2 vs 3 cables with regard to stiffness, peak force, or displacement in the 3 planes tested. Peak force and stiffness were both greater in the 3-cable group, whereas angular and transverse displacement were less in the 2-cable construct.
