Effets de l'arthrodèse tibio-talienne sur la dynamique du pied au cours de la marche

Abstract : Degenerative osteoarthritis in subtalar and midtarsal joints occurring after tibio-talar arthrodesis is thought to be related to consecutive abnormal foot dynamics. Three dimensional gait analysis was performed on nine patients who had an ankle arthrodesis fused in a neutral position and on ten control subjects, in these fol1owing conditions : walking barefoot, walking with customary shoes at self selected speed, walking with shoes at a higher speed, walking with shoes modified by adding standard heels lcm-high, 2cm-high and 2cm-high plus a rocker bar. Walking barefoot, heel-off occurred earlier in the arthrodesis with less anterior tilt of the tibia and more posterior position of the GRF with reference to the metatarsal heads. The use of customary shoes improved greatly but not normalized the abnormal foot dynamics. The use of high-heel shoes improved the GRF progression but the knee kinematics was altered in the arthrodesis group. Ankle and knee dynamics had the most similar values in the arthrodesis and control groups using a 2cm-high heel plus a rocker bar.
