Summary
Hindfoot alignment measurements using plain weight-bearing radiographs and weight-bearing CT scans: a) anteroposterior view, tibiotalar surface angle (TTS) is used to measure inclination of the talus in relation to the tibial axis; b) hindfoot alignment view, the moment arm of the calcaneus and lateral tibio-calcaneal angle are used to assess the hindfoot alignment; c) weight-bearing CT scan, subtalar vertical angle (SVA) is used to measure the subtalar joint axis relative to the ground; d) weight-bearing CT scan, inftal-subtal angle (ISTA) is used to assess the talar morphology and inftal-supcal angle (ISCA) to determine the inclination of the calcaneus in relation to the talus.
