Background: Total Hip Replacement (THR) is a common procedure that is performed increasingly often. Although most patients have satisfactory long-term stability, approximately 17% of prosthetic hips fail, thus requiring revision. Frequently, when hip prosthesis revision is undertaken, there is significant acetabular bone deficiency present; this clinical setting presents one of the most challenging circumstances in hip surgery. There is a variety of surgical hardware and strategies available to address this problem.

Preoperative planning is a critical aspect of any reconstructive hip surgery but is particularly important in revision surgery. The surgeon must anticipate instrument, bone graft and implant requirements for the surgery, as well as which reconstructive options may be needed, based on what may be found intraoperatively. The purpose of this study was to evaluate early functional results of hip arthroplasty with acetabular defects, pelvic bone loss revised with porous tantalum acetabular components.

Methods: 56 patients were operated during research period with different kind of acetabular defects. W.G. Paprosky classification was used to classify existing acetabular defect. From 56 patients 26 was primary hip replacement and 30-revision.

Results: Different kind of tantalum constructions were used to reconstruct acetabular defects during replacement surgery. During research period three patient had complications: Two cases of dislocation after revision replacement (3.6%) and one–after primary replacement (1.8%), one suppuration case (1.8%).

Conclusion: According research results possible to make conclusion: using tantalum augments during acetabular region reconstruction allow to avoid non-biological fixators support rings and structural grafts; tantalum augments are successfully applicable during all kinds of acetabular defects reconstruction, in primary and revision replacement; using tantalum augments during acetabular region reconstruction allow to achieve components stable primary fixation.
