“…Reviewing the literature revealed six relevant studies that assessed the outcome of tantalum cage in lumbar fusion procedures (Table 3). 5,9,10,11,13,18 Cuzzocrea et al 5 , Jalalpour et al 10 , and Hoy et al 9 studied transforaminal lumbar interbody fusion (TLIF), while Lebhar et al 11 , Van de Kelft et al 18 , and Lequin et al 13 studied PLIF. All studies utilizing tantalum cage in lumbar fusion surgery, either TILF or PILF, showed statistically significant improvement of VAS of back pain and ODI at all postoperative follow-up points.…”

“…Assessment of the intersegmental mobility in flexion and extension has been conducted, measuring the angle between the adjacent endplates of the overlying and underlying vertebrae. 11 Tantalum cage was found to be stable when the movement of the two adjacent vertebrae at the index level was ≤5° on dynamic lateral X-rays (flexion and extension films) with no radiolucency between the cage and superior or inferior vertebral endplates. This finding was also considered a radiological sign of good bony fusion.…”

Background Data: Posterior lumbar interbody fusion (PLIF) provides better stability and fusion as a surgical treatment for degenerative disc disease (DDD) and spondylolisthesis. Different cage designs are available for interbody fusion. Tantalum cages are recent and appealing options in these techniques. Purpose: To assess the clinical and radiological outcome of tantalum interbody cage in PLIF without autologous bone graft inside the cage. Study Design: A retrospective case series study. Patients and Methods: A total of 25 patients with single-level DDD (n = 16) or spondylolisthesis (n = 9) who underwent single-level PLIF surgeries with 1-year follow-up were recruited for this study. Clinical and functional assessment was done using the visual analogue scale (VAS) for low back pain and Oswestry Disability Index (ODI). Tantalum cage stability and fusion were assessed radiologically on static and dynamic lateral X-ray. Results: VAS and ODI showed significant postoperative improvement at 6-week and 3-, 6-, and 12-month follow-up intervals. No significant migration or subsidence of tantalum cage was reported on static X-ray, no significant mobility was reported on dynamic X-ray, and the total sound bone fusion rate was 96% at 1-year follow-up. Conclusion: Our data suggest that PLIF with tantalum interbody cage in lumbar DDD and low-grade spondylolisthesis showed good clinical and functional results in 1-year follow-up with high spinal stability and bone fusion rate (2020ESJ225).

“…Though moderate satisfactory clinical results were revealed and significant relieved back and leg pain was only reported in 46% of patients, 85% of patients had possessed remarkable improvement in their working-status post-surgery 1 year [131]. Meanwhile, Lebhar et al [132] and Butler et al [133] respectively reported reliable clinical, functional and radiographic results after the application of porous Ta implant for lumbar intervertebral fusion in their retrospective cohort studies.…”

Porous tantalum (Ta) is a promising biomaterial and has been applied in orthopedics and dentistry for nearly two decades. The high porosity and interconnected pore structure of porous Ta promise fine bone ingrowth and new bone formation within the inner space, which further guarantee rapid osteointegration and bone-implant stability in long term. Porous Ta has high wettability and surface energy that can facilitate adherence, proliferation and mineralization of osteoblasts. Meanwhile, low elastic modulus and high friction coefficient of porous Ta can effectively avoid stress shield effect, minimize marginal bone loss and ensure primary stability. Accordingly, the satisfactory clinical application of porous Ta based implants or prostheses are mainly derived from its excellent biological and mechanical properties. With the advent of additive manufacturing, personalized porous Ta based implants or prostheses have shown their clinical value in the treatment of individual patient who need specially designed implant or prosthesis. In addition, many modification methods have been introduced to enhance the bioactivity and antibacterial property of porous Ta with promising in vitro and in vivo research results. In any case, choosing suitable patients is of great importance to guarantee surgical success after porous Ta insertion.

“…The porous Ta spacer is an optimal choice for reconstruction surgery, and is especially suitable for huge bone defects [ 154 , 155 ]. This is the case because it has adequate structural strength to maintain the restored height and angular correction of the ankle joint until the appearance of osseous fusion between the porous Ta spacer and adjacent bony tissues [ 33 , 151 ], which is significantly different from bone autografts or allografts, either of which may collapse due to absorption after implantation [ 45 , 146 , 152 ]. Moreover, as with cancellous bone, the porous Ta spacer provides the necessary space and osteoconductive environment for vascularized bone tissue ingrowth, obviating autograft-related harvest lesions [ 156 , 157 ] and allograft-related infectious diseases [ 153 ].…”
