Description
Technical Field
The invention belongs to the field of orthopedic medical instruments, and particularly relates to a tibia rotation angle clinical indirect measurer.
Background
CT researches on the rotation evolution of tibia from normal embryo to bone development and maturation show that the tibia is in an increased external torsion state in early embryo life and gradually decreases along with growth and development; when a neonate is born, the tibia is in an internal torsion state, and then the tibia naturally rotates and develops outwards until the average tibia turns outwards for 15 degrees when skeletal development is mature; the abnormal tibia torsion is an important factor for causing lower limb diseases, and the poor rotation of the tibia can cause the problems of bone nonunion, influence on the deformity correction effect, lower limb force line deviation and the like; the measured tibial rotation angle value is measured by a measurer specially used for indirectly measuring the tibial rotation angle when treating diseases such as fracture, valgus varus deformity, traumatic acquired deformity and the like, and the measured angle value and the CT measured value have no statistical difference, so that the method can be used for guiding and applying the method to the diseases caused by the tibial torsion abnormality;
3D model reconstruction is carried out on the tibia of a study object consisting of a plurality of adult males and females, 3D reconstruction models are led into 3-matic software, and the average length of the tibia is 358+/-22 mm (295-431 mm), the length of the tibia on the left side is 358+/-22 mm (296-424 mm), and the length of the tibia on the right side is 358+/-22 mm (295-431 mm) after a series of analysis and calculation; the length of the male tibia is (365+/-19) mm (323-431 mm), and the length of the female tibia is (342+/-18) mm (295-397 mm);
Tibia rotation is continuously changed before 15 years old, rotation in the change range is not required to be treated, early treatment is required to be carried out when the rotation is out of the range, basic development is complete after 15 years old, physiological exorotation angle is formed, and therefore the research object is people over 15 years old and adults; the tibia of a normal adult has a certain torsion angle, the average value of the normal torsion angles of the tibia of a national person is 23.5 degrees, the normal range is 13.5 degrees to 33.5 degrees, and the tibia is in torsion deformity when being larger or smaller than the normal range, so that the tibia needs to be corrected; the correction method mainly comprises the steps that through tibial rotation osteotomy, an osteotomy plane is generally selected to be at a position 20mm below a tibial tuberosity, after the tibia is osteotomy, the distal end of the tibia is rotated, then steel plates are internally fixed, foot deformity is actively corrected, normal load force lines of lower limbs are recovered to the maximum extent, and long-term deformity recurrence of patients is reduced; at present, the tibial torsion angle is gradually known by vast clinicians, and the measurement method is improved along with the development of medical technology;
The measurement methods of the tibial torsion angle are mainly divided into three categories: firstly, the cadaver measurement is directly carried out, the measurement is directly carried out on the cadaver, the result is visual and accurate, but the cadaver measurement is separated from the whole body and cannot be carried out in a living body, and the clinical application is less; secondly, indirect evaluation is carried out through clinical examination, living bodies can be repeatedly and directly measured through clinical examination, the living bodies are convenient and harmless to human bodies, but accurate osseous mark points are difficult to find, the result is inaccurate, and no better clinical indirect measurement method exists at present; thirdly, imaging detection is carried out by using CT, the CT measurement method can repeatedly carry out measurement on a living body, and the result is accurate; however, the CT measurement requires repeated radiography, which can cause a large amount of radiation to the patient in a short period, and the CT cost is too high, which increases the treatment cost of the common patient;
therefore, a tool specially used for measuring the rotation angle of the tibia needs to be designed, the use is simple and convenient, and the error of the measurement result is small.
