Fixation Artificial Shoulder Joint

How is the Shoulder Endoprosthesis Fixated?

An artificial shoulder joint can be fixated in various ways. In essence, there are two main types of fixation: cemented and cementless:

  • In older patients or those with an unstable bone structure, the joint replacement is fixated using bone cement. This creates a strong bond between the shoulder endoprosthesis and the bone immediately after the surgery.
  • If the bone quality is good, the shoulder joint can be secured without using cement. With this method, the bone slowly grows into the shoulder prosthesis and only forms a strong connection after some time.

This means selecting the right procedure not only depends on the age of the patient, but also on the condition of the bone. The surgeon decides on the appropriate method with the patient during a preoperative consultation.
In many cases, minimally invasive shoulder surgery, known as shoulder arthroscopy, is performed. This reduces any stay in hospital significantly or eliminates the need for it altogether.

Mobilising the shoulder quickly is crucial for the healing process. Physiotherapy exercises are introduced soon after surgery. Active participation in these exercises is the only way to restore mobility to your shoulder. A lack of movement can lead to adhesions or fusions, which result in restricted mobility or pain.

Cemented Shoulder Replacement

This method involves fixating the artificial joint with bone cement.
In most cases it is advisable to use bone cement when implanting a shoulder replacement. The slow bone in-growth of the artificial shoulder joint is avoided and the patient can apply load to their arm again immediately following surgery.

Cementless Shoulder Replacement

In contrast to cemented fixation, the artificial humeral component and the prosthetic cup are wedged into the bone. This means that the rough metallic surfaces of the prosthetic components come into direct contact with the bone, which then gradually grows in. The prerequisite for cementless anchoring of the shoulder prosthesis is good bone quality.
