Dynamic pedobarography (DPB) was performed in 21 patients, 9 male and 12 female with cavovarus foot deformity mostly of Charcot-Marie-Tooth origin. Age ranged from 14 to 52 years (mean 30 y). Twenty-six feet were examined pre- and postoperatively clinically, radiologically and by dynamic pedobarography with a follow-up time from 9 to 49 months (mean 22.5 mo). The EMED SF system was used for data collection during walking. Gait line, contact areas (CA), peak pressures (PP) and pressure time integral (PTI) were determined. According to the contact pattern the examined feet could be divided into three groups with antegrade, retrograde and inversion contact pattern. Data analysis showed postoperatively considerable increase in CA and decrease in PP and PTI. Clinical results such as plantar callosities and "roll over avoidance gait" did not always correlate with pedobarographic data. DPB adds a dynamic component in the diagnosis and management of cavovarus feet but certain limitations exist.
