Shoulder Replacement Surgery


Shoulder replacement surgery involves replacing a damaged shoulder joint caused by trauma or disease with an artificial joint. It can be performed when conventional treatments or other surgical interventions show limited progress. If a rotator cuff is damaged, reverse shoulder replacement can be applied.

Reverse shoulder replacement surgery replaces the joint component with a part with different shapes; a round part for the flat scapular joint surface and a flat part for the round humeral head. It gives a space between humeral head and acromion, allowing for a wider range of motion and easy lifting of the arm. It allows for deltoids to perform the role of a shoulder tendon, giving up the function of disabled rotator cuff tendons.


▶ Shoulder replacement surgery

  • Comminuted fracture of humerus
  • Rheumatoid arthritis or degenerative arthritis
  • Avascular necrosis

▶ Reverse shoulder replacement surgery

  • Retear or concern of retear after rotator cuff repair
  • Dislocation of humeral head out of upper part of the joint surface due to extensive rotator cuff tear, resulting in wear of the cartilage and arthritis.


  • 1.Incise the skin on the shoulder and open the joint capsule while protecting rotator cuff tendons
  • 2.Trim and cut the surface of the humeral head according to the desirable angle and depth for implant.
  • 3.Trim and cut the joint surface of the scapular and insert implant using bone cement
  • 4.Insert polyethylene liner, artificial cartilage, and connect joints
  • 5.Confirm the joint motion and suture the rotator cuff
