EFFECT OF FEMORAL NECK AXIS ANGLES ON STRESS AND STRAIN IN PROLONGED FEMUR: FE STUDY
Konvalinka J.
pages 286 - 289, full text

The presented study deals with the influence of the two femoral neck angles — the anteversion angle and the angle of inclination — on stress and strain in femur lengthened with the intramedullary distraction nail. Five variants of geometry model of femur were created from the CT data for the purpose of this study. All femurs were scaled to the same length. The range of angles of the specimens used in this study was 0.2°—27.8° for the angle of anteversion and 114.0°—141.6° for the inclination angle. The osteotomy and lengthening by 30 mm were simulated for each variant of geometry and the intramedullary distraction nail and screws were then inserted. The influence of femoral neck angles was investigated on the stress in the nail, the strain intensity in callus and the deformation along the mechanical axis. The results suggest the influence of the angle of inclination on the max. stress in nail and the influence of the anteversion angle on the max. strain intensity in callus and the deformation along the mechanical axis.
