What is spring ligament in foot?

The spring ligament is a thick band of fibrous tissue that runs across the arch of the foot, connecting the calcaneus bone (heel bone) to the navicular bone located in the midfoot. It is a critical ligament for the stability and proper function of the foot, as it helps to maintain the height of the arch and support the weight of the body during walking, running, and jumping.

The spring ligament is also known as the plantar calcaneonavicular ligament or the superomedial calcaneonavicular ligament. It is important for shock absorption and plays a crucial role in preventing the collapse of the arches of the foot. When the spring ligament is damaged or weakened, it can lead to a condition called flatfoot or pes planus, where the arch of the foot collapses and the heel bone shifts outward.

Injuries or damage to the spring ligament can occur due to various reasons, such as overuse, excessive force, or trauma. Common symptoms include pain, swelling, and tenderness in the arch or heel of the foot, difficulty in walking, and instability in the foot and ankle. Treatment options may include rest, ice, compression, physical therapy, medication, or surgery, depending on the severity of the injury.
