What is spring ligament of foot?

The spring ligament is a strong, flat band of fibrous tissue that spans the underside of the foot, from the calcaneus bone to the navicular bone. It is also known as the calcaneonavicular ligament. The spring ligament is an important structure in the foot, as it helps to maintain the stability of the arch and to distribute the weight of the body between the heel and the forefoot.

Injuries to the spring ligament can result in a condition known as flatfoot, in which the arch of the foot collapses and the foot becomes pronated (turned inward). Other symptoms of spring ligament injuries may include pain in the arch or heel of the foot, swelling, and difficulty walking or standing.

Treatment for spring ligament injuries may involve rest, ice, physical therapy, and orthotic devices such as arch supports or custom-made shoe inserts. In severe cases, surgery may be necessary to repair or reconstruct the damaged ligament.
