• BACKGROUND
    • Pes planovalgus is one of the most common pediatric skeletal deformities. There have been no studies to analyze in detail the spatiotemporal variables of gait following arthroereisis.
  • PURPOSE OF THE STUDY
    • The purpose of our study was to assess gait parameters in patients with symptomatic flexible flatfoot following treatment with the talus screw.
  • METHODS
    • This was a prospective study assessing the 22 patients treated surgically due to symptomatic flexible flatfoot with the talus screw. Patients underwent gait assessment with a G-Sensor. We analyzed the following gait parameters: gait cycle duration, step length, support phase duration, swing phase duration, double support duration, single support duration, cadence, velocity, step length.
  • RESULTS
    • The post-operative gait parameter assessment for the operated and non-operated foot showed a significant difference only in terms of step length. Cadence increased from the pre-operative mean of 82.29 steps/min to a post-operative mean of 102.94 steps/min. Gait velocity increased significantly from 0.81 m/s before to 0.96 m/s after surgery.
  • DISCUSSION
    • Arthroereisis with the talus screw helps improve gait parameters following surgery. Post-operatively, we observed increased gait velocity and cadence and decreased gait cycle duration in the operated limb.
  • CONCLUSION
    • Short-term biomechanical outcomes of pes planovalgus treatment with the talus screw are good.
