Fig. 7From: A modified and enhanced test setup for biomechanical investigations of the hindfoot, for example in tibiotalocalcaneal arthrodesisRange of motion in degrees for varus/valgus and flexion from machine data (green) and Optotrak (blue). TIB-CAL is the range of motion of the whole construct – measured between tibia and calcaneus. TIB-TAL is the movement in the upper ankle joint (tibia – talus) and TAL-CAL in the subtalar joint (talus – calcaneus)Back to article page
