Reconstruction of which ligament is among vertical talus treatment options?

• A. Spring ligament
• B. Deltoid ligament
• C. Calcaneonavicular ligament
• D. Lisfranc ligament

Answer: (A)

In vertical talus, the main goal is to stabilize the talonavicular joint and restore the height of the talar head to re-create the medial arch. The spring ligament, known as the plantar calcaneonavicular ligament, is the key stabilizer of this joint. Reconstructing the spring ligament re-tensions and repositions the navicular on the talus, helping to correct the deformity and maintain proper arch height. The deltoid ligament provides generic medial ankle stability but does not directly address the talonavicular alignment in vertical talus. The calcaneonavicular ligament is the same structure as the spring ligament, so you’re addressing the same support, but the term most specific to this corrective goal is the spring ligament. The Lisfranc ligament stabilizes the tarsometatarsal joints, which is not the primary issue in this condition.
