Use of Trabecular Titanium Implants for Primary Hip Arthroplasty.

Background: Total hip arthroplasty is an increasingly common procedure. The large number of cases inevitably includes patients who require filling of their acetabular defect even in their primary surgery. The use of a utogenous grafts and allografts as well as resistance rings requires patients to avoid loading the limb for a long time to enable implant integration. This disadvantage may be partially eliminated by using trabecular titanium implants. The aim of this paper is to present the outcomes of the use of trabecular titanium implants in primary hip arthroplasty.

Material And Methods: The study embraced 23 patients (18 women and 5 men) whose primary hip arthroplasty was performed in the Cracow Centre of Rehabilitation and Orthopaedics in the period 2010-2015 and involved placement of a trabecular titanium implant.

Results: Medium-term follow-up revealed improvement according to the modified and traditional Harris Hip Score and reduction in pain according to VAS. Loosening of the implant or infection were not recorded. The use of trabecular titanium allowed for reducing the amount of bone grafts used.

Conclusions: 1. Reconstruction of acetabular defects with trabecular titanium implants may be used in primary hip arthroplasty to produce good clinical and radiographic outcomes. 2. The use of trabecular titanium implants allows for reducing the amount of bone grafts necessary to fill the acetabular defect and enables immediate partial loading of the limb.
