Giant cell tumor of the sacrum is usually silent in initial stages and not diagnosed until achieving a large size. Intralesional curettage of the tumor has lower risk of neurological damage but is with high recurrence rate. Zoledronic acid-loaded cement was demonstrated to have cytotoxic effect on the cell line of giant cell tumor. This study evaluate if zoledronic acid-loaded bone cement would reduce the recurrence rate of sacral giant cell tumor after intralesional curettage. ⋯ We suggested that placement of zoledronic acid-loaded bone cement was an effective adjuvant therapy for sacral giant cell tumor following intralesional curettage.

Lumbar spinal stenosis (LSS) is a lumbar spinal disorder that causes leg symptoms and intermittent claudication. It is reported that the risk factors for low back pain include age, family history, smoking, obesity, work-related physical load, exercise, and depression. This was a multicenter, cross-sectional survey, and the aim of this study was to investigate the prevalence of LSS by age and the relationships between LSS and psychosocial factors and job satisfaction. ⋯ This study investigated factors associated with LSS. The prevalence of LSS increased with age. Perceived stress and strenuous use of the low back or legs might be associated with LSS, and job satisfaction was lower with LSS.

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 investigate the clinical outcomes and imaging features of malignant peripheral nerve sheath tumors (MPNSTs) presenting as spinal dumbbell tumors. ⋯ There is little clinical information relating to spinal dumbbell MPNSTs. We propose that the following imaging features are suggestive of spinal dumbbell MPNSTs: maximal diameter>5 cm, irregularly lobulated shape, boundary indistinguishable from surrounding tissues, and osteolytic bone destruction.

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.
