If an ultrasound of the knee determines that advanced osteoarthritis is hindering the way the joint functions, viscous supplement therapy may be used to help correct some of the problem. During this type of treatment, hyaluronic acid is injected into the joint. It is found naturally in the body, mostly in the synovial fluid of the joints. As a person ages, this fluid can begin to dissipate. By reintroducing the hyaluronic acid back into the joint, it helps to restore movement. The substance acts as a lubricant and allows the bones to move freely. It acts as a cushion so the bones no longer rub against one another as the person moves.
A nerve block helps to manage and control pain. A medication is used to numb a nerve or group of nerves that are associated with a particular area of the body. For example, a trigeminal nerve block works to numb the nerves associated with a particular area of the face. In most cases, a nerve block is used to help manage chronic pain. It can also be used to help eliminate the need for surgery. Doctors may use a nerve block to determine if a surgical procedure would work more efficiently at controlling a patient's persistent, chronic pain. They are also helpful in diagnosing certain types of neurological conditions, such as pinched or damaged nerves. An ultrasound is often used to determine where the nerve block should be used.
Diagnostic ultrasounds are used to check the internal structures of different parts of the body. The bursa, for example, are the small sacs of synovial fluid located in the joints that help to keep the body moving smoothly. If a bursa or the tendons and ligaments of a joint becomes injured, it is important to be able to see just what is going on inside the body. A diagnostic ultrasound gives the doctor a look inside the area to determine if the sac has ruptured or simply collapsed due to overuse, old age, or an injury. Diagnostic ultrasounds can be used almost anywhere in the body where this type of problem may exist. Ultrasounds are safe and offer doctors an accurate look at what is happening inside the body.
