METHOD OF DETERMINING RELATIVE MINERAL DENSITY OF BONE DISTRACTION REGENERATE WITH APPLICATION OF GRAPHIC COMPUTER PROGRAMMES ADOBE^® PHOTOSHOP^®

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, traumatology, orthopedics and radiodiagnostics and is intended for determination of relative mineral density (RMD) of bone distraction regenerate (BDR). Method includes application of computer programmes in processing of digital image of traditional roengenogram, which is examined in programme ADOBE® PHOTOSHOP®, automatically determining mean optic density (D) of isolated zone of BDR and adjacent to it proximal and distant bone tissue in optic units (o.u.). After that BDR RMD is calculated by formula 2×Dr×100/Dp+Dd=Kr(%), where: Dr is mean optic density of BDR (o.u.); Dp is mean optic density of proximal bone fragment (o.u.); Dd is mean optic density of distal bone fragment (o.u.); Cr is BDR RMD (%). If Kr is 100 and higher, BDR RMD is normal, Kr is lower than 100% - RMD is reduced.;EFFECT: method makes it possible to determine degree of BDR "maturity" in dynamics, is universal and non-invasive.;1 ex, 1 tbl, 4 dwg
