Megaprosthesis reconstruction

The megaprosthesis is a modular implant that replaces the resected bone and the neighboring joint, attaching to the remaining bone. Its planning is based on the patient's imaging and, in complex cases, on 3D technology.

Compared with an allograft, the megaprosthesis allows the limb to bear weight and move earlier, so it is usually preferred when rapid functional recovery is the goal; in exchange, it is an implant that can loosen or wear over the years and require revisions.

Rehabilitation is progressive and depends on the location and on how much muscle and tissue had to be reconstructed. When tendons or muscles are reattached —for example, the mechanism that extends the knee or the one that abducts the hip— recovery of that function is slower and sometimes incomplete, and directed physiotherapy is essential.

The goal is a stable, pain-free limb that is functional for the activities of daily life.

A megaprosthesis replaces a large segment of bone, so it is an implant that will stay with you for the rest of your life and requires periodic check-ups. Over the years it can loosen or wear and need a revision, something to be expected especially in young patients because of the many years of use.

Preventing infection is a permanent priority: with dental procedures or infections from any other source, it is best to treat them promptly, because infection is one of the most feared complications of these reconstructions.

The decision to operate is made together: we discuss the diagnosis, the goals of treatment, the expected benefits, the risks and the alternatives. Surgery does not guarantee an outcome; it aims to control the tumor while preserving as much function as possible.
