Plantar ligament plate
A plantar ligament plate is found on the bottom of the foot. This ligament plate connects the toe to the corresponding metatarsal bone of the foot. Each foot contains four of these plates, one for each toe except for the first toe, which does not have a plantar ligament plate. The function of the plantar ligament plate is to keep the toe in its appropriate joint. The plantar ligament plate is made of fibrocartilage, a mix of collagen fibers and tough cartilage. The cell types of the plate include chondrocytes and fibroblasts. The plantar ligament plate can support the weight of the body and resists sideways flexion. A plantar ligament plate can tear or stretch due to injury or overuse. When this occurs, the toe can become dislocated. Severe dislocation of the plantar ligament plate can result in hammertoe. In mild cases, the ligament may heal on its own. In serious cases, a doctor can perform surgery to repair the damaged plantar ligament plate.
