“…2 Further studies were then published demonstrating the versatility of TM with foot and ankle fusion constructs. 8,10,11,[14][15][16]18 Specifically for the large ankle bone defects, Frigg et al used a TM spacer with screws for stabilizing the fusion construct and showed bone ingrowth with Micro-CT. 8 Henricson et al described using a TM implant with iliac crest autograft and an intramedullary nail for stabilization. Horisberger et al also used an intramedullary TTC nail with their case series, 11 and 2 other studies used different plating constructs to stabilize the fusion.…”

Technique for Use of Trabecular Metal Spacers in Tibiotalocalcaneal Arthrodesis With Large Bony Defects

There are many causes of large bone defects in the tibiotalar joint that need to be definitively treated with a tibiotalocalcaneal (TTC) arthrodesis. Some of the challenges of a large defect are its effect on leg length and the complications associated with trying to fill the defect with structural bone graft. We present an operative strategy involving the use of a trabecular metal implant, a TTC nail that utilized 2 forms of compression, and Reamer/Irrigator/Aspirator (RIA) autograft, to address limitations of previous operative approaches and reliably treat this operative challenge.

“…When ankle replacements fail, large defects left by the prosthesis require a large volume of bone substitution with robust strength and biocompatibility. 162 It is a technically challenging task for many reasons such as aseptic loosening, mechanical failure, or periprosthetic infection. 163 TM spacers with 80% porosity were designed to mimic the natural bone architecture and to allow significant bony ingrowth.…”

“…Porous Ta was mostly reported in the tibiotalocalcaneal arthrodesis or namely ankle arthrodesis; the porous Ta used here has an official name of trabecular metal ankle fusion spacer (Zimmer). When ankle replacements fail, large defects left by the prosthesis require a large volume of bone substitution with robust strength and biocompatibility . It is a technically challenging task for many reasons such as aseptic loosening, mechanical failure, or periprosthetic infection .…”

Porous metal is metal with special porous structures, which can offer high biocompatibility and low Young’s modulus to satisfy the need for orthopedic applications. Titanium and tantalum are the most widely used porous metals in orthopedics due to their excellent biomechanical properties and biocompatibility. Porous titanium and tantalum have been studied and applied for a long history until now. Here in this review, various manufacturing methods of titanium and tantalum porous metals are introduced. Application of these porous metals in different parts of the body are summarized, and strengths and weaknesses of these porous metal implants in clinical practice are discussed frankly for future improvement from the viewpoint of orthopedic surgeons. Then according to the requirements from clinics, progress in research for clinical use is illustrated in four aspects. Various creative designs of microporous and functionally gradient structure, surface modification, and functional compound systems of porous metal are exhibited as reference for future research. Finally, the directions of orthopedic porous metal development were proposed from the clinical view based on the rapid progress of additive manufacturing. Controllable design of both macroscopic anatomical bionic shape and microscopic functional bionic gradient porous metal, which could meet the rigorous mechanical demand of bone reconstruction, should be developed as the focus. The modification of a porous metal surface and construction of a functional porous metal compound system, empowering stronger cell proliferation and antimicrobial and antineoplastic property to the porous metal implant, also should be taken into consideration.
