Total shoulder replacement surgery replaces your shoulder's damaged bone 和 cartilage with a metal 和 plastic implant. The shoulder is a ball-和-socket joint, much like the 臀部 joint. The ball is the top of the arm bone (the humerus) 和 the socket is within the shoulder blade (the scapula). During shoulder replacement surgery, the ball is removed from the top of the humerus 和 replaced with a metal implant. This is shaped like a half-moon 和 attached to a stem inserted to the center of the arm bone. The socket portion of the joint is then replaced with a plastic socket that is cemented into the scapula.
Shoulder Replacement
The procedure takes approximately two hours. However, the preparation before the operation 和 the recovery afterward may take several hours. 病人 often spend two hours in the recovery room 和 two to three days in the hospital after surgery.
You will be admitted to the hospital on the day of your scheduled surgery. You will be asked to arrive two hours before the start of your surgery. Once you are admitted, you will be evaluated by an anesthesiologist. The most common type of anesthesia is regional anesthesia, where your arm will be numbed by placing anesthetic medicine into your neck before the start of the operation. Supplementary anesthesia will then be given through an intravenous (IV) drip that keeps you asleep for the entire surgery. You will discuss this with your anesthesiologist prior to your surgery.
Advanced Surgical Techniques
Total shoulder replacement can be a very successful operation, similar to 臀部 和 膝盖 replacement surgeries. However, it is a difficult operation 和 the surgeon should be well trained to perform it. 加州大学旧金山分校, we are investigating the possibility of image-guided surgeries to better identify the anatomy 和 bone structures of each shoulder, so that we can improve the outcome of shoulder replacement surgery. We are investigating the possibility of doing the surgery with smaller 和 less traumatic approaches, so that the rehabilitation can be quicker 和 less painful.
