Subtrochanteric Fracture following Removal of a Porous Tantalum Implant [PDF]

Case Reports in Orthopedics, 2013
Osteonecrosis of the hip accounts for about 10% of all total hip arthroplasty cases and presents a significant challenge for those patients with and without femoral head collapse. Subtrochanteric femur fractures have been reported with numerous types of proximal femoral implants.

Porous Tantalum Acetabular Cups in Primary and Revision Total Hip Arthroplasty: What Has Been the Experience So Far?—A Systematic Literature Review [PDF]

Biomedicines
Background: The global population, especially in the Western world, is constantly aging and the need for total hip arthroplasties has rocketed, hence there has been a notable increase in revision total hip arthroplasty cases.

3D-printed porous tantalum for acetabular reconstruction in complex primary arthroplasty and revision of hip [PDF]

Frontiers in Bioengineering and Biotechnology
IntroductionIn cases of hip joint damage, such as osteoarthritis (OA), rheumatoid arthritis (RA), avascular necrosis, or hip fractures, total hip arthroplasty (THA) is a critical surgical intervention.

Stress distribution pattern in all-on-four maxillary restorations supported by porous tantalum and solid titanium implants using three-dimensional finite element analysis [PDF]

European Journal of Translational Myology
Success/failure of dental implants depends on stress transfer and distribution at the bone-implant interface. This study aimed to assess the stress distribution pattern in all-on-four maxillary restorations supported by porous tantalum and solid ...

Highly Porous Tantalum Acetabular Components Without Ancillary Screws Are Non-inferior at 7 Years When Compared With Titanium Components With Ancillary Screw Fixation: A Randomized Controlled Trial [PDF]

Arthroplasty Today
Background: While porous tantalum components have shown to be advantageous in the revision setting, registry studies have identified tantalum components used in primary total hip arthroplasty (THA) to be associated with an increased risk of revision. The

Progress of 3D printed porous tantalum in orthopedics

Di-san junyi daxue xuebao, 2019
Tantalum, known as "pro-biometal", has excellent bio-inertness and bio-compatibility. Pure tantalum has been used in orthopedics for longer than 80 years. But pure tantalum has little in common with bone tissue in the elastic modulus and is not conducive

Osseointegration Effects of 3D-Printed Porous Titanium–Tantalum Scaffolds with Different Tantalum Contents

ACS Omega
Titanium (Ti) is known for its excellent corrosion resistance and its biomechanical properties. However, its bioinert nature and high elasticity result in suboptimal osseointegration. In contrast, tantalum (Ta) demonstrates superior osteogenesis and osseointegration but has a high elastic modulus and density, making it costly to process. In the present

Research progress in application of porous tantalum implant for treatment of bone defects

Cailiao gongcheng, 2022
Porous tantalum metal has good biocompatibility and osteoconductivity, with a lower modulus of elasticity and a higher coefficient of friction to avoid stress-shielding compared with traditional implant metal materials. In addition, its porous structure,

Single-Level Anterior Cervical Discectomy and Interbody Fusion: A Comparison between Porous Tantalum and Polyetheretherketone Cages. [PDF]

J Pers Med, 2022
Background: Anterior cervical discectomy and interbody fusion (ACDF) may be performed with different kinds of stand-alone cages. Tantalum and polyetheretherketone (PEEK) are two of the most commonly used materials in this procedure.
