Weight-bearing computed tomography is an important part of diagnosis of acquired foot deformities. Authors presents the results of the application of functional weight-bearing MSCT (fMSCT) in determining the standard angular parameters in patients with elastic type of pes planus, as well as a comparative analysis with the data of classical MSCT without weight-bearing.

Purpose. To determine the possibility of fMSCT in determining the degree of flatfoot deformity using the angular parameters of the foot.

Materials and methods. The study included 36 patients (59 feet) with 1 degree of pes planus of one or two feet. The mean age of patients was 42±7.5 years. All patients underwent a two-stage visualization (fMSCT and MSCT) on a multispiral computed tomograph Toshiba Aquilion One using the author's technique (patent No. 2659028). All patients underwent evaluation of the angular parameters of the foot to determine the degree of deformation.

Results. The use of functional weight-bearing MSCT is an accurate non-invasive tool in determining the angular parameters of the foot in pes planus..
