Ligaments Injuries

Ligaments support and strengthen joints. Their main function is to keep the bones of the skeleton in proper alignment and prevent abnormal movements of the joints.

Ligaments are bands of strong, flexible tissue that connect bones together throughout the body. They allow movement between bones, which allows you to do things like flex your foot or move your fingers. While ligaments are extremely strong, an awkward stretch or twist can cause a strain injury. With enough force, they can be torn—the most severe ligament injury. When ligaments are stretched or strained beyond normal capacity, they can tear. There are three grades of ligament injury: grade 1, a mild ligament tear; grade 2, a moderate ligament tear, and grade 3, a complete ligament tear, otherwise known as a rupture.
