The long plantar ligament is a strong and wide strip of tissue that can be found at the bottom of the foot. Out of the three ligaments in the foot, it is the longest. It acts as a connection between the second metatarsal and the fifth metatarsal. Although the thickness of this ligament can differ based on its position, it generally remains consistent. The short plantar ligament, on the other hand, measures around six to nine centimeters in length, but in some instances, it may be longer.
The long plantar ligament plays a crucial role in stabilizing the calcaneocuboid joint, which is often associated with ankle and foot pain. It also provides stability to the midtarsal and calcaneocuboidic joints. Moreover, the long plantar ligament is protected by the peroneus longus tendon tunnel.
The calcaneonavicular ligament differs from the long plantar ligament in its length and width. While the long plantar ligament attaches to the front of the calcaneus, the calcaneonavicular ligament is shorter and wider. On the other hand, the short plantar fascia extends from the heel to the base of the toes. Another small tendon, known as the calcaneocuboid, connects the navicular bone to the calcaneus.
The long plantar ligament is composed of multiple bands attached to the calcaneus. These bands are located in different locations and can be detected by ultrasonography. In addition to the length of the long plantar ligament, it is the location of various structures. Its low signal intensity and rectangular shape make it easily visible in all planes, although it is best visualized in the sagittal and coronal planes.
The long plantar ligament is made up of two bands that attach to the navicular and the calcaneus. The long plantar ligament is the most common ligament in the human foot and is the most important for stability and balance. It is an essential part of the foot and contributes to the covering of the peroneus longus tendon tunnel. When it is intact, the long plantar ligament is connected to the peroneus.
The long plantar ligament is one of the two inferolateral plantar ligaments. It is connected to the midtarsal joint and stabilizes the plantar-medial calcaneocuboid joint. The long plantar ligament has a narrow proximal insertion at the calcaneus and a wide central and lateral band on the metatarsal bases. It also contributes to the covering of the peroneus longus tendon tunnel.
The long plantar ligament connects the calcaneus to the metatarsals and assists in the formation of the longitudinal arch of the foot. The long plantar ligament supports the calcaneocuboid joint, which stabilizes the midtarsal joint. The short plantar ligament, on the other hand, runs deeper than the long one. The former is the origin of the small foot muscles, while the latter fortifies the talotarsal joint capsule.
The long plantar ligament is a long plantar ligament. It connects the second metatarsal to the fifth. Its distal part is deep, while the distal part is shallow. Its proximal part is wider and covers the peroneus longus tendon tunnel. Its proximal origin lies at the inferior and plantar aspects of the calcaneus.
The long plantar ligament is medial to the calcaneonavicular ligament. It attaches to the navicular and anterior calcaneus. The two are similar, but the navicular ligament is broader than the long plantar ligament. However, the short plantar is shorter than the long one. It courses between the inferior cuboid and the anterior calaneus.
The long plantar ligament is a thick fibrous band of connective tissue that attaches the second and fourth metatarsal bones. The distal band is made up of two bands. Each of them has a triangular and a rectangular superficial band. Its surface appears striated and has intermediate signal intensity. The deep band attaches to the navicular bone, while the other two bands attach to the calcaneocuboid.
The long plantar ligament was removed by surgically separating the peroneal longus tendon from the long plantar ligament. It was found to be 33.7 mm in length and 4.6 mm wide. The long plantar ligament connects the transverse and longitudinal arches. These structures are called the longitudinal and transverse suspensory metatarsal ligaments. These are the two ligaments that provide the connection between the long and short metatarsal bones.
