MR evaluation of talonavicular angle in congenital talipes equinovarus

The talonavicular relationship in 14 patients with talipes equinovarus was quantified using gradient echo sequences. The angle formed between the shor t axis of the navicular and the long axis of the talus was measured. There is a significant difference in the talonavicular angle between patients who had posteromedial release (PMR) and those who had posterior release (PR) o r casting only (P=.0004). This method provides an objective assessment of r esidual deformity following surgical and conservative management of talipes equinovarus. (C) 2001 Elsevier Science Inc. All rights reserved.
