You will receive general anesthesia, so that you’ll sleep through the operation and won’t feel anything. (Or, you may receive local anesthesia and a medicine to help you relax.) Someone will carefully monitor your vital signs, like your heart rate and blood pressure, during the operation. You may have a breathing tube inserted down your throat during the operation to help you breathe.
After cleaning the affected area, your surgeon will make an incision through the skin and muscle of your arm. For certain types of injuries, your surgeon might make an incision through the top of your shoulder instead.
Your surgeon will bring the pieces of your humerus back into alignment (reduction).
Next, your surgeon will secure the pieces of humerus to each other (fixation). To do this, he or she may use screws, metal plates, wires, and pins. (Ask what the surgeon will use in your case.)
Your doctor will make any other necessary repairs.
After the team has secured the bone, your doctor will surgically close the layers of skin and muscle around your arm.
