| Popis: | Anterior lumbar interbody fusion (ALIF) is a common procedure for patients with degenerative pathologies of the lumbar spine. In this study, the clinical and radiological outcomes of a combination titanium/polyetheretherketone (Ti/PEEK) ALIF cages in one, two and three-level surgery were evaluated. Over an 18-month time period, a prospective single surgeon series of 20 implants (15 patients) were included in the study, with minimum 10-months follow-up. From these 15 patients, two were supplemented with posterior percutaneous pedicle screw fixation for additional stability. Radiological follow-up with fine cut CT scan at 9-12months was performed to evaluate early fusion rates, and integration of the Titanium/PEEK cage at the endplate junction. 20 implants were followed for a minimum of 10months, and a mean of 15months. A 95% (19/20 implants) fusion rate with no implant related complications was achieved at the mean 15-month postoperative mark. Patients experienced statistically significant improvement in pain and functional outcomes (SF12 and ODI) compared to their pre-operative status. A single patient with a non-union at L5/S1 (smoker) did not experience any improvement in symptoms. A Ti-PEEK cage, with allograft and BMP-2 to achieve interbody fusion is an effective implant for use in anterior lumbar surgery with high fusion rates, no lucency around the titanium endplates at follow-up, and with promising early results. |
