Plantar accessory ligaments are ligaments that are located at the bottom of the foot and connect the sole to the bones of the foot. They play an important role in maintaining balance and stability when walking.
The plantar accessory ligaments consist of several layers of muscles and ligaments. The first layer is the plantar fascia, which is an elastic membrane that connects the sole and bones of the foot. The second layer is the longitudinal ligament of the foot, which runs along the entire length of the foot and connects it to the lower leg. The third layer is the transverse pedal ligament, which connects the sole to the midfoot.
The functions of the plantar accessory ligaments include:
- Maintaining balance and stability while walking.
- Provides shock absorption when walking to protect feet from shock and injury.
- Participation in the formation of the arch of the foot, which provides shock absorption when walking and reduces the load on the joints.
- Participation in stabilizing the position of the foot when standing and sitting.
- Helps maintain proper foot position during running and other physical activities.
- Participating in the regulation of foot temperature, as they can transfer heat from the foot to the lower leg.
However, if the plantar accessory ligaments are damaged or weakened, it can lead to various health problems such as foot pain, foot deformities, gait disturbances, and even joint injuries. Therefore, it is important to monitor the condition of these ligaments and consult a doctor at the first sign of damage.
Additional plantar ligaments - l. accessorius plantarias or ligaments of plantar cords - l. tendoceplorum plantarium is a continuous continuation of the plantar ligament on the posterior surface of the metatarsal head. Attachment. Superior attachment to the tubercle of the base of the 5th metatarsal, the base of the 1st metacarpal bone and the tendon of the palmaris longus muscle. Inferior attachment: to the two heads of the peroneal muscles, to the lateral interosseous membrane of the foot. Function. The function of the plantar accessory ligaments is to strengthen the ligamentous apparatus of the foot, maintain the supporting function of the foot and lower leg, and also stabilize movements in the joint.
