Revision total hip arthroplasty (THA) is challenging specially in the presence of severe acetabular bone deficiency. We report the use of a highly porous revision shell augmented by structural allograft to provide structural support and coverage to the acetabular component. ⋯ Trabecular metal shells combined with structural bone allograft in revision THA demonstrate excellent midterm survival, with 94% of acetabular components obtaining stable union onto host bone at 5 years. Allograft restored bone stock with minimal resorption, and when it occurred did not alter the survivorship of the acetabular component.

The purpose of this study is to review our experience with Kerboull reinforcement device combined with bulk allograft for management of severe acetabular defects. ⋯ Despite massive bone defects, we achieved favorable results for revision THA using bulk allograft and the Kerboull reinforcement device.

The efficacy and costs of indwelling interscalene catheter (ISC) and liposomal bupivacaine (LBC), with and without adjunctive medications, in patients with primary shoulder arthroplasty are a source of current debate. ⋯ The intraoperative LBC mixture provided equivalent pain relief with significantly fewer major complications and at markedly lower cost than ISC. LBC required almost twice as much OME to attain the same level of pain relief at 24 hours, but there was no significant difference in the cumulative amount of outpatient narcotic use.
