The connection between the heel bone and the fourth metatarsal bone is formed by the short plantar ligament. This ligament, which is relatively wide, has the ability to handle significant amounts of force. It plays a role in supporting the lateral arch of the foot, along with other components such as the calcaneus bone, cuboid bone, long and short talus bones, and the extensor tendons and muscles of the little toe.

Plantar ligaments can be classified into two types: long and short. The long plantar ligament is characterized by its length and forms a flat fibrous band. This ligament attaches to the second to fifth metatarsals and the posterior cuboid bone. Its main function is to guide the tendon of the long peroneal muscle, which inserts on the base of the first metatarsal. On the other hand, the short plantar ligament is shorter than its long counterpart.
The foot is supported by several ligaments that play important roles in maintaining its structure and stability. One such ligament is the long plantar ligament, which is known for being the longest ligament in the foot. This ligament extends from the heel bone to the base of the metatarsals, contributing to the formation of the foot’s longitudinal arch. It also provides stability to the calcaneocuboid and midtarsal joints. On the other hand, the short plantar ligament, as its name suggests, is shorter and deeper than the long plantar ligament. It is situated on the lateral side of the calcaneus, adding additional support to the foot.
The long plantar ligament is the longest ligament and connects the calcaneus to the cuboid bone. It runs slightly medial to the long plantar ligament and is called the calacaneocuboid ligament. The long plantar ligament is located on the plantar aspect of the cuboid bone. It also contributes to the covering of the peroneal tendon tunnel.
The short plantar ligament is a small piece of fibrous tissue that stretches from the calcaneus to the base of the metatarsals. It serves as a stabilizing force for the midtarsal joint and assists in the formation of the longitudinal arch of the foot. However, the long plantar ligament is shorter than the short one and is deeper than the short one. In the foot, it is the lateral portion of the midtarsal joint.
The long plantar ligament is the longest and runs from the heel bone to the base of the metatarsals. It is a Y-shaped band that serves as a support for the midtarsal joint. It is the most important ligament in the foot because it provides a stable foundation for the mid-foot. Its role is to stabilize the talotarsal joint and to aid in foot movement.
The short plantar ligament is a ligament that stretches between the cuboid bone and the inferior calcaneus. Its anterior origin is the talus. The short plantar ligament lies deep to the long calcaneocuboid joint and is also medial to the long plantar ligament. It is located on the plantar side of the cuboid bone.
The long plantar ligament extends from the calcaneus to the base of the metatarsals and connects the inferior calcaneus to the cuboid bone. It is slightly medial to the long plantar ligament. Its proximal origin is located on the anterior tubercle of the calcaneus. It is responsible for stabilizing the midtarsal joint and the talotarsal joint capsule.
The short plantar ligament is a short, cone-shaped ligament that connects the cuboid bone to the inferior calcaneus. It is similar to the long plantar ligament, but is broader and deeper. Both are important for proper foot health. If the short plantar calcaneocuboid is inflamed, it is important to have the short plantar ligament trimmed.
The plantar fascia is a complex structure that connects the various bones in the foot and ankle. The plantar fascia connects the heel to the toes, while the plantar calcaneo-cuboid ligament connects the heel to the talus. The ligaments stabilize the foot and give it its arch structure. When one of them is injured, the other two ligaments must forcefully lengthen the arch. As a result, the calf tendon becomes flatter and the arch of the foot falls.
