Computed tomography in bone density measurement and vertebral rotation assessment before and after surgical treatment of scoliosis
Journal Title: Ortopedia Traumatologia Rehabilitacja - Year 2004, Vol 6, Issue 4
Abstract
Background. There are changes on radiograms of bone tissue structure after surgical treatment in scoliosis.The aim of the study. The aim of the current study is the assesment of bone density and vertebral rotation in apical part of spine scoliosis before and afrter surgical treatment.Materials and methods. Computed tomography examination was performed on young girls with right-side thoracic scoliosis, before and after surgical correction and spine stabilisation. Three-dimensional option (3D) was used to examine vertebrae from the peak of spine distortion. Bone density measurement in various parts of vertebral bodies and archs on concave and convex sides was performed, both before and after operation. Analogical examination of vertebral rotation in the superior part of spine was executed as well. Results and Conclusions. Preliminary results and conclusions based on analysis of rotation before and after surgical CD method treatment with a use of titanic grafts were presented. Postoperative examination has shown that rotation in the peak of spine distorsion remained unreduced. The grafts used to scoliosis correction have no influence on peak part of spine distorsoin. Bone density changes in vertebrae consisted in increased values on more loaded side and decreased values on less loaded side in accordance to Delpech-Wolf`s principle. Bone density increased also after spondylodesis with a use of autogenic bone grafts.
