METHOD OF ESTIMATING DEGREE OF PATHOLOGICAL BONE RESTRUCTURING IN PATIENTS WITH VITAMIN D-RESISTANT RICKETS

摘要

FIELD: medicine. ^ SUBSTANCE: invention relates to medicine, namely to radiodiagnostics, and can be used for estimation of bone state in patients with vitamin D-resistant rickets by method of computer tomography. Computer tomography of Looser's zone is performed. On obtained axial sections pathological part of bone is determined. Quantitative evaluation of its density in zone of restructuring is carried out. In case of segmental thinning of cortical plate without involvement into the process of zone of bone marrow canal with density within 450-600 HU, first stage of pathological restructuring of bone is diagnosed. In case of cortical plate thinning in combination with presence of sclerosis in zone of bone marrow canal with density 601-750 HU second stage of pathological restructuring of bone is diagnosed. If pathological process spreads on entire bone diameter in combination with sclerosis of bone marrow canal with density 751-900 HU third stage of pathologic bone restructuring is diagnosed. ^ EFFECT: method makes it possible to increase treatment efficiency due to increase of objectivity of pathological bone restructuring degree in patients with vitamin D-resistant rickets. ^ 3 dwg, 3 ex
