Single trabecular titanium Cup-Cage for acetabular bone defects during revision hip arthroplasty: Mid-term outcomes.

ABSTRACT:

Background

Severe acetabular bone loss remains a major challenge in revision total hip arthroplasty (rTHA). Traditional cup-cage techniques can provide stability but are associated with technical complexity and mixed long-term outcomes. The Delta TT system, a trabecular titanium construct functioning as a single cementless cup-cage, may combine biological fixation with mechanical reliability. This study aimed to evaluate its mid-term clinical and radiographic outcomes in complex acetabular reconstructions.

Methods

In this prospective cohort (2018-2021), 64 patients (mean age: 68.4 years) with Paprosky type II (n = 38) or type III (n = 26) acetabular defects underwent rTHA using the Delta TT system. Functional outcomes were measured with the Merle d'Aubigné and Postel score p
