Biocompatibility and Osseointegration of Calcium Phosphate-Coated and Non-Coated Titanium Implants with Various Porosities.

Unlabelled: was to study the influence of pore size and the presence of a biologically active calcium phosphate coating in porous 3D printed titanium implants on the process of integration with the bone tissue.

Materials And Methods: Samples of cylindrical implants with three different pore diameters (100, 200, and 400 μm) were fabricated from titanium powder on the Arcam 3D printer (Sweden) using electron beam melting technology. A calcium phosphate coating with a thickness of 20±4 μm was applied to some of the products by microarc oxidation.

A prospective randomised comparison of earlier function after total hip arthroplasty with a mini posterior approach or supercapsular percutaneously-assisted total hip approach: a gait analysis study.

Background: The supercapsular percutaneously-assisted total hip (SuperPATH) approach is a muscle sparing surgical technique for total hip arthroplasty (THA). The literature reports good clinical and functional results of the SuperPATH technique in the short term. We aimed to compare early outcomes and gait analysis of THA using the mini posterior approach (MPA) and supercapsular percutaneously-assisted total hip (SuperPATH) approach.

[Characteristics of periprosthetic femoral fractures after total hip replacement in elderly patients.].

In our study we analyzed 76 patients (78 hip joints) with periprosthetic femoral fractures after total hip replacement treated at Privolzhsky Federal Research Medical Centre in 2006-2016 period. We outlined specific features of periprosthetic fractures in elderly patients such as women having it more often, arise due to traumatic causes. Also elderly patients require more elaborate hardware such as cerclage wires, periprosthetic plates and additional surgical techniques such as extended trochanteric osteotomy to successfully treat periprosthetic fractures.
