Post-Traumatic Hindfoot Arthritis.J Orthop Trauma. 2020 Feb; 34 Suppl 1:S32-S37.JO
The hindfoot is functionally defined as the articulations between the talus, calcaneus, navicular, and cuboid. It is a biomechanically important peritalar unit for shock absorption and propulsion with the subtalar and talonavicular joint essential to its function. The primary cause of hindfoot arthritis is post-traumatic. Other causes include long-term misalignment such as adult-acquired flatfoot, cavus foot, and inflammatory arthritis. Prevention of post-traumatic hindfoot arthritis is the primary objective. Anatomical reduction and fixation of articular hindfoot fractures is the preferred pathway. This article discusses the principles of treatment of hindfoot arthritis. When post-traumatic changes cannot be managed by nonsurgical means, an anatomical well-aligned arthrodesis is indicated. This article addresses the principles of managing this condition, which have been championed by Professor Sigvard T. Hansen. New approaches and techniques are discussed that achieve the goals of a stable, functional plantigrade foot.
