Total hip arthroplasty is a common surgical treatment for elderly patients with osteoporosis and further discussion is needed if use of such acetabular components is justified under the condition of normal bone mass.
There is a need to perform studies to compare of osseintegration of two different types of titanium implants [3-dimensional (3D)-printed and plasma-coated titanium implants].
To determine the features of osseointegration of two different types of titanium implants (3D-printed and plasma-coated titanium implants) in bone tissue of a distal metaphysis in a rat femur model.
This study was performed in a rat femur model. Histological examination of the femur was carried out by measuring the relative perimeter of bone trabeculae [bone-implant contact (BIC%)] and bone marrow surrounding of 3D-printed titanium implant (highly porous) and plasma-coated titanium implant.
Trabecular bone tissue was formed on the 45th day after implantation around the implants regardless of their type. Forty-five days after surgery groups with different implants did not differ in BIC%, but after 90 d, the BIC% was higher in 3D-printed titanium implant group.
The use of a highly porous titanium implant, manufactured with 3D printing, for acetabular components provides increased osseointegration compared to a plasma-coated titanium implant.
Further research studies on the use of other histological and biomechanical methods will help to determine the optimal materials of acetabular implants in terms of structure and complexity of their manufacture to be used in patients with normal bone mass.
