Total Shoulder Replacement
Your shoulder joint
Your shoulder is made up of three bones:
- The collar bone, or clavicle (KLAV-ick-ol)
- The shoulder blade, or scapula (SKAPyou-luh)
- The bone of the upper arm, or humerus(HYOO-mer-es)
The rounded end of the humerus is called the head. The head fits into a hollow in the scapula. The hollow is called the glenoid (GLEE-noid). The head and glenoid fit together like a ball and socket and form the shoulder joint.
Why you need surgery
Usually arthritis or a fracture makes surgery necessary. Arthritis can wear down the head of the humerus over time. A fracture can break the head into many pieces. Shoulder replacement surgery replaces the head of the humerus.
During your surgery
During surgery, the head of the humerus is removed. A metal ball that is shaped like the head of the humerus is inserted into the glenoid. The metal ball is called a prosthesis (pross-THEE-sis). A prosthesis is an artificial part. A plastic prosthesis shaped like a cup is inserted into the glenoid. Both artificial parts are fit together. Then the incision is closed and a sterile dressing is put on.
After your surgery
The following list tells you what you need to know and do after your surgery.
- Your doctor will prescribe pain medicine for you.
- Your doctor also may tell you to put ice packs on your shoulder.
Care of your incision
- If you have a dressing over your incision, keep the dressing clean and dry.
- If your incision is open to the air, keep the area clean and dry.
- If Steri-Strips tape covers your incision, keep the Steri-Strips clean and dry. They will peel off on their own.
- Do not put any lotion or ointment on your incision, unless your doctor says you may.
To prevent movement
- Your doctor may prescribe that you wear a sling. Wearing a sling helps to keep the
shoulder joint from moving. Your doctor will tell you how long you need to wear the sling.
- If you wear a sling, your arm should be at a 90-degree angle at the elbow. Your wrist and hand should be supported by the sling. Do not allow your wrist and hand to hang over the sling.
- It is important to keep your underarm area clean and dry.
- Gently clean the underarm area daily with soap and water.
- Ask your doctor when you are allowed to shower. Until then, you should take a sponge bath (not a tub bath).
- Do not lift with your affected arm until your doctor says you may. Your doctor will tell you how much you can safely lift.
- Your doctor will talk to you about a program of rehabilitation and exercise. Your doctor will tell you when to start doing your exercises.
- Your doctor may order a CPM machine to help you move your shoulder. CPM stands for continuous passive motion. If CPM is ordered, your nurse will explain how the machine works.
