Femoral Stem for Artificial Hip Joint and Artificial Hip Joint Including the Same

A femoral stem 2 for artificial hip joint is provided that is capable of tightly fixing a greater trochanter and is suitable for treatment of transcervical fracture where it is necessary to fix the greater trochanter. The femoral stem 2 comprising: a stem member 20 including a distal part 21 of the stem member which is inserted in a medullary cavity of a femur and fixed therein and a proximal part 22 of the stem member which has a neck 26 for fixing an artificial head and is positioned at a proximal end of the distal part, the distal part and the proximal part being integrated or separable; a plate fixing portion 36 which is detachably attached at a top of the proximal part; and a greater trochanter plate 3 for depressing the greater trochanter 71, the greater trochanter being fixed to the plate fixing portion 36 at a certain angle or fixed to the plate fixing portion so as to adjust an angle. Since the greater trochanter plate 3 is fixed onto the femoral stem 2 of the present invention, the greater trochanter is tightly fixing and thus the fixation can be stabilized. Furthermore, since the greater trochanter plate 3 is fixed at the top of the proximal part 22, the greater trochanter plate 3 covers the top of the greater trochanter 71 when the greater trochanter 71 is fixed. Therefore upward displacement of the greater trochanter by a gluteus medius musculus can be effectively suppressed.

InactiveCN108334730AProven AccuracyMeet the requirements of finite element analysisEducational modelsSpecial data processing applicationsHuman bodyBone Cortex
The invention provides a human body body hip modeling and simulation method based on muscle groups, and relates to the human body hip modeling and simulation method based on the muscle groups. The object of the method is to solve the problem that existing human hip models cannot take into account refined human body structures and finite element simulation implementing, and the human body hip modeling and simulation method based on the muscle groups is provided. The method comprises the steps of first, acquiring human hip image data; second, conducting geometric modeling on human hip, which includes geometric three-dimensional reconstruction of hip bone (cortical bone and cancellous bone), thigh bone (cortical bone and cancellous bone), articular cartilage, sartorius muscle, musculi quadriceps femoris, biceps femoris, semitendinosus, semimembranosus, gracilis, phalanges, long adductors, short adductors, adductor muscles, gluteus maximus, gluteus medius, gluteus maximus and entire hip; third, establishing muscle group models, conducting model assembly on the hip bone, the thigh bone, the articular cartilage, the muscle groups and the whole hip, establishing a fat and skin model, andadding tendon; fourth, determining meshing parameters, determining inter-tissue contact relationship, and implementing the meshing of the geometric models; fifth, attaching materials to the structureof each part of the human hip model, and determining the material parameters; sixth, achieving mechanical simulation of the human hip model. The method is used in the field of biomedical engineering.
