Abstract
Background
Though the anterior lumbar interbody fusion with cages is an interesting option in the treatment of discogenic low back pain, cage-related complications opened the way to alternative options like circumferential fusion or recent ALIF techniques using cages and anterior instrumentation. As the latter are rather recent, the aim of this prospective study was to quantitatively evaluate the early outcomes after ALIF with anterior cage and plate construct.
Methods
Pre- and postoperative data of 41 patients (mean age 42 years) were analyzed from a clinical, socio-professional, quality of life and biomechanical point of view, with a mean follow-up of 1.8 years. Evaluation was based on clinical data, four scores (SF-12, JOA, VAS, patient satisfaction index) and several radiological parameters (describing spine geometry and balance) for an accurate outcome assessment.
Results
In 1 and 2 years follow-up exams, good and excellent outcomes were found in 92% of cases, associated with high levels of quality of life (83%) and satisfaction (95%), but also with a late return to work (40% at 1 year and 76% at 2 years). Outcome was not related to postoperative disc narrowing, observed in 15% of patients. Radiological parameters values highlighted normal spine geometry and balance in 71% of cases and were postoperatively constant in most patients.
Conclusion
From a clinical and functional point of view, the early outcomes after ALIF with cage and plate were in agreement with success ranges in the literature; they were completed by good levels of quality of life and patient’s satisfaction. In addition to subsidence detection, biomechanical analysis offered a detailed insight into the evolution of the treated segment and on its impact on spine’s stability and balance.
