Types of Shoulder Arthroscopy

Hemiarthroplasty: Only the head of the humerus is removed and replaced with an artificial component.

Total shoulder arthroplasty: Both the head of the humerus and the glenoid are replaced. A plastic cup-shaped device is fitted into the glenoid, and a metal ball-shaped device is attached to the top of the humerus.

Reverse total shoulder arthroplasty: This is called “reverse” because the position of the metal ball-shaped device and plastic cup-shaped device are reversed. The metal ball is attached to the glenoid and the plastic cup is attached to the top of the humerus. In certain patients including those with rotator cuff arthropathy, this is the best approach for restoring overhead motion of the arm, alleviating pain, and restoring overall shoulder joint functioning.

Resection arthroplasty: This is the most common surgical procedure used to treat arthritis of the AC joint. A small amount of bone from the end of the collarbone is removed, leaving a space that gradually fills in with scar tissue.
