Kinematic foot types in youth with pes planovalgus secondary to cerebral palsy.

Background: Kinematic variability of the foot and ankle segments exists during ambulation among individuals with pes planovalgus (PPV) secondary to cerebral palsy (CP). Clinicians have previously recognized such variability through classification schemes to identify subgroups of individuals, but have been unable to identify kinematic foot types.

Research Question: The purpose of this work was to identify kinematic foot types among children with PPV secondary to CP using 3-dimensional multi-segment foot and ankle kinematics during gait as inputs for principal component analysis (PCA) and K-means cluster analysis.

Aortic Endograft Infection by Pasteurella multocida: A Rare Case.

Infection of an aortic endograft is a rare complication following endovascular aneurysm repair. These patients have been treated with explantation of the graft to obtain source control followed by an extra-anatomic bypass to restore circulation. The present case study describes an interesting case of Pasteurella infection involving an aortic endograft managed nonoperatively by percutaneous drainage and graft preservation.
