USE OF TANTALUM CUP IN TOTAL HIP ARTHROPLASTY-A NARRATIVE REVIEW.

Tantalum, known for its superior mechanical properties and biocompatibility, has revolutionized the field of acetabular reconstruction, especially in revision total hip arthroplasty (rTHA). This review explores the clinical indications, biomechanical and biological properties, benefits, risks, and outcomes associated with tantalum acetabular components, particularly in managing complex cases of acetabular deficiencies. Extensive research has highlighted tantalum's ability to promote osseointegration, provide high survivorship rates, and maintain mechanical stability even in the most challenging cases, such as pelvic discontinuity and severe bone loss. However, challenges remain, including high costs and the need for long-term studies in primary total hip arthroplasty (THA). This article aims to provide a comprehensive overview of tantalum's current role in THA, discussing the potential for broader applications in primary surgeries and the implications of its high cost on healthcare systems.
