Postoperative cage migration and subsidence following TLIF surgery is not associated with bony fusion – Lumbar Fusion

Day Case Lumbar Fusion Surgery

The article titled “Evaluation of cage migration and subsidence following lumbar interbody fusion” discusses the occurrence of pseudarthrosis, cage migration, and subsidence after transforaminal interbody fusion (TLIF) in the lumbar spine. The study aimed to assess the influence of cage migration and subsidence on fusion and clinical outcomes. The researchers analyzed CT scans of 67 patients who underwent monosegmental TLIF and evaluated the position of the cages. The results showed that postoperative cage migration occurred in 85.1% of patients, and cage subsidence was observed in 58.2%. However, neither cage migration nor subsidence had an impact on fusion or clinical outcomes. The incidence of cage migration was significant, but its clinical significance was considered limited as it was not associated with bony fusion. Overall, there was no correlation between clinical and radiographic outcomes

ABSTRACT

Pseudarthrosis following transforaminal interbody fusion (TLIF) is not infrequent. Although cage migration and subsidence are commonly regarded as evidence of the absence of solid fusion, there is still no evidence of the influence of cage migration and subsidence on fusion. This study aimed to evaluate cage migration and subsidence using computed tomography (CT) DICOM data following lumbar interbody fusion. The effects of cage migration and subsidence on fusion and clinical outcomes were also assessed. A postoperative CT data set of 67 patients treated with monosegmental TLIF was analyzed in terms of cage position. To assess the effects of cage migration and subsidence on fusion, 12-month postoperative CT scans were used to assess fusion status. Clinical evaluation included the visual analog scale for pain and the Oswestry Disability Index. Postoperative cage migration occurred in 85.1% of all patients, and cage subsidence was observed in 58.2%. Radiological signs of pseudarthrosis was observed in 7.5% of the patients Neither cage migration nor subsidence affected the clinical or radiographic outcomes. No correlation was found between clinical and radiographic outcomes. The incidence of cage migration was considerable. However, as cage migration and subsidence were not associated with bony fusion, their clinical significance was considered limited.
