hemiartroplastikk

Hemiartroplastikk is a surgical procedure used to treat conditions involving the shoulder joint, specifically those that cause instability or pain. The term "hemiartroplastikk" is derived from the Greek words "hemi," meaning half, and "arthroplastikk," referring to joint replacement. The procedure involves the removal of a portion of the humeral head, followed by the insertion of a prosthetic component to restore the joint's stability and function.

The primary indication for hemiartroplastikk is the treatment of glenoid bone loss, which can occur due to conditions such as osteoarthritis, traumatic injuries, or tumors. By removing a portion of the humeral head, the surgeon can create a more stable and congruent joint surface, reducing pain and improving range of motion. The prosthetic component used in hemiartroplastikk is typically made of metal or ceramic and is designed to mimic the natural shape and function of the humeral head.

The surgical technique involves several steps. First, the surgeon creates an incision over the shoulder joint and exposes the glenoid and humeral head. A portion of the humeral head is then removed using a reamer or drill, creating a larger socket for the prosthetic component. The prosthetic component is then inserted into the socket, and the incision is closed. Postoperatively, patients typically experience significant pain relief and improved shoulder function.

Hemiartroplastikk is considered a viable option for patients with glenoid bone loss who have not responded to conservative treatments or who are not suitable candidates for total shoulder replacement. The procedure has been shown to provide good to excellent results in terms of pain relief, functional improvement, and long-term durability. However, like any surgical procedure, hemiartroplastikk carries risks, including infection, implant failure, and revision surgery. As with any surgical intervention, patients should discuss the benefits and risks of hemiartroplastikk with their healthcare provider to make an informed decision.
