To determine the frequency of major complications and identify related risk factors in surgery for hypervascular spinal tumors after preoperative selective arterial embolization. ⋯ Major complications in surgery for hypervascular spinal tumors after embolization are prevalent. Risk factors identified in this study are useful prognostic indicators when considering surgical treatment combined with embolization.

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.

Age-related loss of functional muscle mass is associated with reduced functional ability and life expectancy. In disseminated cancer, age-related muscle loss may be exacerbated by cachexia and poor nutritional intake, increasing functional decline, morbidity and accelerate death. Patients with spinal metastases frequently present for decompressive surgery with decision to operate based upon functional assessment. A subjective assessment of physical performance has, however, been shown to be a poor indicator of life expectancy in these patients. We aimed to develop an objective measure based upon lean muscle mass to aid decision making, in these individuals, by investigating the association between muscle mass and 1-year survival. ⋯ Death within 1 year in individuals with spinal metastases is related to lean muscle mass at presentation. Assessment of lean muscle mass may inform decision to operate in patients with spinal metastases.

Technical note. ⋯ The reported technique can be applied for chest wall reconstruction in cases of total or subtotal vertebrectomy accomplished with the resection extending towards rib cage. It appears to be straightforward, safe and effective allowing good cosmetic and functional outcome.

Spinal dumbbell-shaped schwannoma is common neoplasm, usually occurring in the cervical spine. Posterior or anterolateral approaches are frequently used to remove this benign tumor. We analyzed how much amount of tumor could be possible to be totally removed with posterior approach. ⋯ Total removal of intra- and extraforaminal cervical subaxial schwannomas could be possible using a posterior approach with facet removal if the size of extraforaminal tumor was less than 5.4 mm.
