Lower Extremity Biomechanics and Pathologies

Calcaneocuboid joint pressures were evaluated with eight cadaver specimens. Real-time pressures were recorded using a TekScan 4200 sensor pad at lengths of 0, 5, and 10 mm in both unloaded and 350-newton loaded models. Recorded pressures exceeded 2.3 MPa in the loaded model at 10 mm lateral column lengthening. Although an acceptable procedure in the pediatric population, application of the Evans lateral column lengthening procedure for management of adult acquired flatfoot may generate excessive pressures leading to joint arthrosis. Lengthening by calcaneocuboid distraction arthrodesis may avoid this problem.
