Basically, a joint is a part of the body where two bones connect. Ligaments and other fibrous tissue connect the two bones, and tendons connect muscle to the bone or cartilage. There are six types of joints in the human body, including ball and socket joints, hinge joints, condyloid joints, pivot joints, gliding joints, and saddle joints. Any type of blunt force trauma can cause a joint injury, and car accidents are one of the most common causes of this type of injury. Oftentimes, the body will instinctively try to brace itself for the force of the impact by bending or twisting the arms, legs, back, and pelvis area. These movements, combined with the force of the impact, can cause damage to the joints, tendons, and ligaments.
