Renal cell carcinoma (RCC) is an aggressive disease that metastasizes to the spine often requiring surgery. However, selecting the appropriate surgical intervention can be challenging. The Tokuhashi scoring system can be used to predict survival and inform the surgical strategy. We set out to determine the Tokuhashi score for patients with RCC spine metastases and compare expected and observed survival. ⋯ RCC is an aggressive disease with short life expectancy when metastatic to the spine. However, patients with low systemic disease burden and solitary spinal metastases can have long survival and benefit from excisional surgery. Tokuhashi score can be useful in selecting surgical intervention in patients with RCC spinal metastases, and may be more relevant than in other cancers with spinal metastases.

To evaluate the feasibility and clinical improvement of a total posterior arthroplasty system in the surgical management of lumbar degenerative spondylolisthesis and or spinal stenosis. ⋯ In patients with spinal stenosis and degenerative spondylolisthesis, decompression and posterior arthroplasty with the TOPS System can maintain clinical improvement and radiologic stability over time.

To evaluate the benefits of minimally invasive balloon kyphoplasty (BKP) in patients with cancer and painful pathologic vertebral lesions. ⋯ Minimally invasive BKP provided excellent long-term palliation of pain and improved mobility in patients with cancer and painful osteolytic spinal lesions or vertebral fractures.

We aimed to study the relationship between two morphological parameters recently described on MRI images in relation to lumbar spinal stenosis (LSS): the first is the sedimentation sign (SedS) and the second is the morphological grading of lumbar stenosis. ⋯ One-third of surgically treated LSS patients do not present a SedS. This sign appears to be a lesser predictor of treatment modality in our setting of symptomatic LSS patients compared to the severity of stenosis judged by the morphological grade.

This study aimed to investigate the association between the clinical symptoms of central lumbar spinal stenosis (CLSS) and morphological parameters using magnetic resonance imaging (MRI) data. ⋯ Larger LFA and LFT values are associated with higher ODI values. A larger DSA and SCA are associated with a longer SWD before claudication occurs. To evaluate CLSS patients, clinicians should more carefully inspect the integral morphological parameters than the individual morphological parameters.
