Osteogenesis imperfecta

Joints are the regions of the body where one or more bones are connected, typically enabling movement such as bending, twisting, and more. The ends of the bones that come together in a joint are covered with articular cartilage, which provides cushioning and prevents bone-on-bone friction during movement. Ligaments, which are fibrous bands, contribute to joint stability and regulate the range of motion to prevent dislocation. Additionally, muscles are usually connected to the bones around the joints through tendons (see Figure 17). When a muscle contracts, exerting force, it pulls on the tendon, which in turn pulls on the bone. This mechanism enables the movement of our body.
