Method for quantitative assessment of bone block formation in the area of anterior fusion

摘要

FIELD: medicine.SUBSTANCE: to quantify the bone unit formation in the anterior spine fusion zone is carried out by CT on the device with slice thickness of max. 1 mm in the sagittal and coronal projections of standard MPR-reconstructions. Unit evidence is estimated by the sagittal and coronary projections of standard MPR-reconstructions separately in the upper and lower blocked divisions in points, where 1 means transplant/implant ends offset outside the support sites of blocked vertebrae; 2 means no transplant/implant ends offset outside the support sites of blocked vertebrae, diastaz between the bed and the bone transplant is 3 ≥mm; 3 means no transplant/implant ends offset outside the support sites of blocked vertebrae, diastaz between the bed and the bone transplant 3 mm; 4 means no diastaz between the bed and the bone transplant, the convergence area is heterogeneous, sclerous; 5 means no diastaz between the bed and the bone transplant, the convergence area is homogenous, bone beams extend directly between them.EFFECT: nethod allows to evaluate the dynamics of bone unit evidence in the area of anterior spine fusion at different stages of the postoperative period due to standardized assessment.4 tbl, 18 dwg, 3 ex
