To assess implant performance, to evaluate fusion and to assess clinical and radiologic outcome of circumferential fusion using porous tantalum cages for ALIF in a 360-degree fusion.

A retrospective cohort study was performed over a 4-year period that included the implantation of 280 tantalum cages in 98 patients by the technique of anterior lumbar interbody fusion (ALIF) and posterolateral spondylodesis. Radiographic follow-up was performed to document any implant related problems. Preoperative and postoperative clinical outcome measures were assessed.

No neurological, vascular or visceral injuries were reported. There were no rod breakages and no symptomatic non-unions. One revision procedure was performed for fracture. Mean VAS back pain score in our patient cohort improved from 7.5 preoperatively to 1.9 at latest follow-up, mean VAS leg pain score improved from 6.2 to 1.1 and mean ODI score improved from 51.1 to 18.3.

Porous tantalum cages have high strength and flexibility, in addition to having similar biomaterial properties to cancellous bone. Their use in 360-degree spondylodesis to treat degenerative lumbar spine deformity has been demonstrated to be very safe and effective, with excellent clinical and functional outcomes.
