Study Summary
In 1997, the FDA approved the use of Trabecular Metal™ (Zimmer, Trabecular Metal Technology, Inc., Parsippany, NJ) for acetabular cups, a porous tantalum structural biomaterial that was developed to address the limitations of other implant materials, with the potential to improve implant fixation. Porous tantalum (80% porosity) offers potentially greater ingrowth and bone graft incorporation, believed to be restricted by the low porosity of other commonly used implants (30%). Additionally, the low modulus of elasticity property (3 MPa) of porous tantalum provides more normal physiological loading conditions which theoretically reduce stress shielding and resultant bone loss surrounding the implant. These properties are much desired advantages for implants used in cementless THA. Various porous tantalum implants have shown favorable clinical results. Unger et al. reported excellent bone graft incorporation of the acetabular component based on serial radiograph data at a minimum 1-year follow-up. Dual-energy X-ray absorptiometry (DEXA) is a well-established method for detecting periprosthetic bone mass changes around the femoral and acetabular THA components. The primary objective of this study is to quantify and compare periprosthetic bone mineral density (BMD) changes in THA revision patients receiving Trabecular Metal™ and metal-backed acetabular components, measured using DEXA scanning techniques. Additionally, this study will analyze and compare clinical outcomes of these patients, based on SF-12v2 and HOOS.
Primary Outcome
Quantify and compare periprosthetic bone mineral density (BMD) changes in THA revision patients receiving Trabecular Metal™ and metal-backed acetabular components, measured using DEXA scanning techniques. Region 1 forms the superior-lateral region, Region 2 forms the superior-medial region, and Region 3 forms the inferior-medial region around the acetabular component. For each region, the mean change in BMD was calculated using the following equation described by Wilkinson et al (J Bone Joint Su
