Ps. Cooper et al., CALCANEOCUBOID JOINT PRESSURES WITH LATERAL COLUMN LENGTHENING (EVANS) PROCEDURE, Foot & ankle international, 18(4), 1997, pp. 199-205
Calcaneocuboid joint pressures were evaluated with eight cadaver speci
mens. Real-time pressures were recorded using a TekScan 4200 sensor pa
d 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 th
e pediatric population, application of the Evans lateral column length
ening procedure for management of adult acquired flatfoot may generate
excessive pressures leading to joint arthrosis. Lengthening by calcan
eocuboid distraction arthrodesis may avoid this problem.
