Customized endoprostheses

A customized (or custom-made) prosthesis is a tailored prosthesis developed and manufactured considering specific anatomical features of an individual patient.

A customized (or custom-made) prosthesis is a tailored prosthesis developed and manufactured considering specific anatomical features of an individual patient.

Custom-made prostheses are used in the most difficult cases, when serial products are inapplicable. Most frequently, they serve for massive defects of bone tissue.

For a background of an individual implant, a CT scan data are processed to obtain a 3D model. The process of designing such a device takes place in a tight cooperation between a surgeon and an engineer. After approval, the construction is embodied using a “titanium” 3D printer.

Unfortunately, there are no perpetual hip prosthesis. In 15-20 years (sometimes even more), the prosthesis may demand replacement, complete or partial. If a patient appears to the physician on time, with the first signs of the instability, the component will be just replaced with a larger one.

Sometimes, the revision arthroplasty takes place earlier. For instance, in a case of inflammation after the initial arthroplasty, when the prosthesis had been replaced with a temporary spacer with antibiotics.

If a surgeon encounters large bone defects, special revision systems may be implanted. Sometimes, in the most difficult cases, individual 3D printed prosthetic components can be applied.
