To review a series of ten cases with epithelioid hemangioendothelioma of the spine, that have undergone surgery to describe clinical presentation, results and complications associated with surgical treatment; a review of literature reporting the main characteristics of the cases already published has been reported. ⋯ Wide surgery is probably associated with a better prognosis. Indeed most deaths and local recurrences reported in literature happened after intralesional surgery or chemotherapy/RT alone. The presenting study suggests that the best approach to achieve long-term local control and a major survival could be wide surgery, nevertheless more cases series are necessary to verify survival rate.

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.

Randomized Controlled Trial
IPD without bony decompression versus conventional surgical decompression for lumbar spinal stenosis: 2-year results of a double-blind randomized controlled trial.
Interspinous process devices (IPDs) are implanted to treat patients with intermittent neurogenic claudication (INC) based on lumbar spinal stenosis. It is hypothesized that patients with lumbar spinal stenosis treated with IPD have a faster short-term recovery, an equal outcome after 2 years and less back pain compared with bony decompression. ⋯ This double-blinded study could not confirm the advantage of IPD without bony decompression over conventional 'simple' decompression, two years after surgery. Moreover, in the IPD treatment arm, the reoperation rate was higher and back pain was even slightly more intense compared to the decompression treatment arm.

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.

The medial branch of the posterior ramus of the lumbar spinal nerve is well known to be innervated independently and to end in the multifidus muscle without anastomosis. This prospective cohort study aimed to determine the diagnostic specificity and sensitivity of multifidus muscle denervation (MMD) by needle electromyography (N-EMG) for lumbar foraminal and lateral exit-zone stenosis (LF/LEZS). ⋯ Needle electromyography is a simple and available additional method for the diagnosis of LF/LEZS.
