Surgery may be done using a general anesthetic, which puts you completely to sleep, or a local anesthetic, which numbs only the hand. The procedure takes about two hours to complete. The artificial joint functions the same way a hinge on a door does. Surgeons use silicon plastic implants to replace the original joint surfaces. Surgical Procedureīefore we describe the procedure, let's look first at the artificial finger joint itself. In general, finger joint surgery can be done on an outpatient basis, meaning you can leave the hospital the same day. The length of time you spend in the hospital depends a lot on your recovery from anesthesia after surgery. You shouldn't eat or drink anything after midnight the night before. On the day of your surgery, you will probably be admitted to the hospital early in the morning. This exam helps ensure that you are in the best possible condition to undergo the operation. Your surgeon may suggest a complete physical examination by your regular doctor. Once you decide on surgery, you need to take several steps. If you have concerns or questions, you should talk to your surgeon. You need to understand as much about the procedure as possible. The decision to proceed with surgery must be made jointly by you and your surgeon. The artificial joint is used to replace the damaged joint surfaces so patients can do their activities with freedom of movement and less pain.

When this material wears out, the joint develops a type of arthritis called osteoarthritis and becomes painful. This material is the slick, spongy material that allows one side of a joint to slide against the other joint surface easily. The joint surfaces are covered with a material called articular cartilage. The joint capsule is a watertight sac around the joint. These ligaments join to form the joint capsule of the finger joint. Several ligaments hold each finger joint together. Ligaments are tough bands of tissue that connect bones together. The joint near the end of the finger is called the distal IP joint (DIP joint). The one closest to the MCP joint (knuckle) is called the proximal IP joint (PIP joint). Each finger has three phalanges, separated by two interphalangeal joints (IP joints). It is formed by the connection of the metacarpal bone in the palm of the hand to the finger bone, or phalanx. The main knuckle joint is the metacarpophalangeal joint (MCP joint). The finger joints work like hinges when the fingers bend and straighten. what to expect before and after surgery.Joint replacement surgery is called joint arthroplasty. If nonsurgical treatments are not successful in easing problems of finger arthritis, your doctor may recommend replacing the surfaces of the joint.
