Description
Technical field
The present invention relates to orthopaedics field of measuring technique, and in particular to a kind of 3 D stereo femoral head dimension measuring device.
Background technology
Femoral head is exactly two bones for supporting body top half, and specific location is below pelvis, and pelvis there is on one side
One acetabular bone, two femorals head just coordinate with acetabular bone, play the role of supporting upper body.If seen from the outside exactly in buttocks
The back lower place.Femur is the most important bone of human body, and femoral head is even more important, and the walking upright of people, activity, labour depend on femur
The supporting role of head.So femoral head is also to be easiest to injured position.
The indication of artificial femoral head replacement is mainly：60 years old or more the elderlys, stock neck head mo(u)ld bottom half fracture, displacement
Obviously, healing is had any problem；Neck of femur head mo(u)ld bottom half comminuted fracture；The disunion of neck of femur old fracture or neck of femur are inhaled
It receives；It is unable to the fracture of neck of femur patient of partner treatment, such as hemiplegia, Parkinson's disease or mental patient；Adult idiopathic or wound
Property avascular necrosis of femoral head range it is big, and acetabulum injuries do not weigh, and cannot be repaired again with other operations；It should not go and strike off bone grafting operation
Neck of femur benign tumour；The malignant tumour or cause pathologic fracture of neck of femur primary or transfer can to mitigate patient's pain
With operating substitution.
The selection of artificial thigh bone size, in principle should be big with former femoral head etc..Its diameter can be slightly smaller but no more than
2mm, excessive easy cause joint space is narrow and hyperplasia of cortical and traumatic arthritis occurs；It is too small, it is uneven to will produce acetabular bone
Ground bears pressure, and acetabular bone easy to wear and charge into pelvic cavity.Therefore diameter preoperative, that femoral head should be carefully measured in art, it is general to use
Vernier caliper measurement, can also in the preoperative in suffer from hip same plane place prosthesis head take the photograph X-ray film measure.It is suitable such as to select, in art
It is middle to be put into femoral head when being tested in acetabular bone, should can freely activity, and have certain negative pressure when pulling out.To artificial thigh bone
Neck length selection it is also critically important, no matter with which kind of prosthese, it is necessary to lesser trochanter upper limb to the distance between acetabular bone be made to restore normal.
Long easy cause pain and centre type dislocation, it is too short, it is easy to walk lamely, it is same to be easy damage acetabular bone.
Therefore, preoperative femoral head is accurately measured is necessary, and can select the size of artificial thigh bone
It selects error and is reduced to minimum, reduce postoperative a variety of disease palindromias, reach good postoperative curative effect.
