Screw joint The screw joint is a joint that is formed between the articular processes of the second cervical vertebra and the manubrium of the sternum. This joint is also called the first dry joint. The structural features of the joint can contribute to the displacement of the vertebrae relative to each other during movements in the cervical spine. Therefore, for the proper functioning of the screw joint, it is important to follow the doctor’s recommendations for its strengthening and prevention. The knee joint screw is an anatomical element of the anterior cruciate ligament of the knee joint. It is characterized by repeated repetition of monotonous movements of the joint, which can lead to deformation of the joint in the frontal plane. As a result, the usual subluxation develops.
