Abstract
- Abstract—The state of stress in the femur–hip stem biotechnical systems with uncemented and cemented use for revision arthroplasty is calculated using a finite element method and the ANSYS software package. 3D finite element models are developed for these systems and a healthy intact femur. The stress levels in bone structures and the deformation characteristics of the system models at a load of 3300 N are calculated. The high degree of similarity of the biomechanical behavior of all models indicates the operability of the stems of both designs. The stress levels in the cemented- and uncemented-implant stems are found to be 2–3 times lower than the fatigue limit of the initial deformed semifinished product made of a VT6 titanium alloy. This fact indicates the reliability of the implant stems of the proposed designs. [ABSTRACT FROM AUTHOR]
