Hindfoot Alignment Valgus Moment Arm Increases in Adult Flatfoot With Achilles Tendon Contracture.

The article presents a study on the hindfoot alignment valgus moment arm in adult flatfoot with Achilles tendon contracture. The study measured standing hindfoot alignment, standing lateral tibial-calcaneal angle, lateral talo-first metatarsal angle, lateral medial cuneiform arch height and anteroposterior talonavicular coverage angle in 22 patients. The researchers conclude that there is increased standing valgus alignment moment arm in adults with flatfoot and Achilles tendon contracture.
