A 10-Year Follow-up Evaluation of Lumbar Spine Fusion With Pedicle Screw Fixation

Abstract

At a minimum follow-up evaluation of 10 years, lumbar fusion with pedicle screw fixation showed relatively good functional capacity, especially relative to the baseline, a low rate of radiographic failure, satisfaction of patients with their progress, a low rate of repeat surgery, and minimal surgical and hardware-related complications.

Factores de riesgo que afectan la fusión en el tratamiento de la inestabilidad en la columna lumbar

“…Lo más importante es que pueden ser detectados desde la consulta externa, lo que en algunos casos la probabilidad de una pseudoartrosis ser prevenible, tal es el caso de la propia obesidad, acompañada de una valoración especifica del IMC, la hipoalbuminemia y la linfopenia [6][7][8][9] . La obesidad como factor único puede incrementar un 5% la probabilidad de una pseudoartrosis, que si le agregamos factores como la hipoalbuminemia, este se puede incrementar hasta un 42% la probabilidad de un resultado no deseado 8,10,11 . La densidad ósea también nos marca una probabilidad del 33% y la edad mayor de 60 años puede llegar a ser siete veces mayor la probabilidad de que no exista una fusión en la zona de la cirugía 7,12,13 .…”

Reply to the letters of Prof. K. Buettner-Janz and Mr. H.D. Link concerning “Charité total disc replacement: clinical and radiographical results after an average follow-up of 17 years” by M. Putzier et al.

“…In contrast, it is comparable to numerous other long-term follow-up examinations [2,4,8,10]. Apparently, the editor and the reviewers of the reputable European Spine Journal share this opinion, otherwise they would not have approved the publication of our data in such a highly ranked journal.…”

Correlative radiological, self-assessment and clinical analysis of evolution in instrumented dorsal and lateral fusion for degenerative lumbar spine disease. Autograft versus coralline hydroxyapatite

“…Oblique views of the instrumented spine were used in the present study to accurately evaluate intersegmental bony fusion because the presence of hardware made it difficult to interpret bony fusion on the classical anteroposterior (AP) and lateral views. In the bending tests, angular motion on flexion-extension radiographs of 5°or more and sagittal plane translation (olisthesis) on flexionextension radiographs of 3 mm or more were considered as instability [26]. CT scans were performed in all cases preoperatively, as well as 12 months and 24 months postoperatively, to evaluate facet joint arthrodesis (Fig.…”
