Multispiral computer tomography (MSCT) in the assessment of bone quality in patients with congenital leg pseudoarthrosis

Purpose. To study the radiomorphological characteristics of leg bones in patients with leg bone congenital pseudoarthrosis using the technique of multispiral computer tomography in order to assess “bone quality”. Materials and Methods. 20 patients with leg congenital pseudoarthrosis (LCP) at the age of 8-40 years examined by the technique of radiography and computer tomography before and after treatment, and after recurrence including. Results. MSCT demonstrated to allow revealing maximally possible number of the anatomic and structural characteristics of leg bones in patients with congenital pseudoarthrosis which may be of importance for surgical intervention planning. Conclusion. The intravitally revealed changes in leg bone architectonics coincided with the results of the histological studies made in the same patients, thereby allowing to interpret bone state at different stages of treatment quite accurately. The information obtained confirms the data of bone remodeling defect in the zone of pseudoarthrosis, reducing osteoblastic potential, in connection with which the problems of treatment of such patients appear.
