Can tibial tantalum cones eventually eliminate the adjuvant use of metallic augments for AORI type 2B/3 metaphyseal defects??-A novel surgical technique and case series.

Background: For extensive metaphyseal defects, the use of tantalum cones is usually combined with adjuvant stems which may be cemented/cementless and metallic bone augments for additional stability. A Tibial baseplate-Cone construct with proud tibial cones and without metallic augments has been described for AORI type 2B/3 tibial defects.

Methods: A case series analysis of 6 patients with AORI type 3 defects treated with unstepped proud Tantalum tibial metaphyseal cones without metallic wedges/full width augments.

Management of radiation induced, bilateral Primary THA loosening with an aseptic Paprosky Type IIB acetabular defect and a contralateral septic Type IIIB acetabular defect: A case report and review of literature.

Introduction: Primary THA in an irradiated hip poses risk for early loosening and inadequate ingrowth.Adverse effects such as decreased vascularity and increased infection risk pose a threat.

Case Presentation: Our patient was a case of post-irradiation (for cervical cancer) bilateral THA loosening causing aseptic acetabular loosening on one side and catastrophic septic loosening with a Paprosky type IIIB acetabular defect with pelvic discontinuity on the contralateral side.
