Tritanium acetabular wedge augments: short-term results

Area of Science:

• Orthopaedic Surgery
• Biomaterials Engineering
• Reconstructive Medicine

Background:

• Acetabular defects in total hip arthroplasty (THA) pose significant challenges for surgeons.
• Previous research explored trabecular metal augments, but short-term outcomes of tritanium acetabular wedge augments remain unevaluated.

Purpose of the Study:

• To evaluate the short-term clinical and radiographic outcomes of tritanium acetabular wedge augments in THA.
• To assess the safety and efficacy of this specific augment system in reconstructing acetabular defects.

Main Methods:

• Retrospective analysis of a prospective database (January 2013-December 2014) of primary and revision THA patients.
• Inclusion criteria: tritanium acetabular wedge augment system and minimum 2-year follow-up (average 2.2 years).
• Collected demographic, clinical (Harris Hip Score, SF-36), and radiographic data (Paprosky, Crowe, DeLee and Charnley classifications).

Main Results:

• Study included 8 patients (4 revision THA, 3 DDH, 1 posttraumatic arthritis).
• No radiographic lucency observed at latest follow-up; no open revision surgeries during the follow-up period.
• Significant improvements in SF-36 physical and mental scores, Harris Hip Score, pain, and function postoperatively.

Conclusions:

• Tritanium acetabular wedge augments demonstrate high clinical outcome scores in this short-term series.
• The augment system showed no radiographic lucency or early failures.
• These findings suggest tritanium acetabular wedge augments are a viable option for acetabular defect reconstruction in THA.
