METHOD OF PRE-OPERATION PLANNING OF SURGICAL TREATMENT OF HIP JOINT INSTABILITY IN CASE OF TORSION HIP SUBLUXATION IN CHILDREN

摘要

FIELD: medicine.;SUBSTANCE: invention relates to field of medicine, namely to orthopedics. X-ray examination of patient's hip joints in position at 65° between frontal plane of pelvis and screen and estimation of angle of anterior covering of hip head are carried out. Additionally second roentgenogram is made at maximal internal rotation of affected extremity with further comparison on X-ray images of values of angles of anterior covering of hip head, between rays originating from head centre vertically and to the point of anterior-lateral edge of cavity arch. In case of present disturbances of hip joint stability with angle of anterior covering of hip head (AACHJ) equal not less than 18°, identified on the first X-ray image, and in case if on the second X-ray image with AACHJ more than 18°, corresponding to the norm, correcting (detorsion) osteotomy of hip in independent version, is planned. In case of pathologic values of AACHJ on the second X-ray image too, correction of position of both pelvic and femoral hip joint components is planned.;EFFECT: method ensures increase of accuracy and self-descriptiveness of X-ray examination of hip joints and pre-operation determination of volume and efficiency of planned surgical intervention.;4 dwg
