For the selection of treatment in patients with spinal bone metastases (SBM), survival estimation plays a crucial role to avoid over- and under-treatment. To aid clinicians in this difficult task, several prediction models have been developed, consisting of many different risk factors. The aim of this systematic review was to identify prognostic factors that are associated with survival in patients with SBM to support development of predictive models. ⋯ Prognostication for patients with SBM should be based on an accurate primary tumor classification, combined with a performance score. The benefit of adding other prognostic factors is doubtful.

Surgical complications of extraspinal tumors in the cervical spine: a report of 110 cases and literature review.
To assess the safety of surgical intervention for extraspinal tumors in the cervical spine. ⋯ Surgery for cervical spine tumor could improve the quality of life, though it might be accompanied with high morbidity and mortality. It is a highly demanding procedure; however, it can be performed to an acceptable degree of safety.

Kyphoplasty and vertebroplasty have become one of the most frequent surgical procedures in the treatment of vertebral compression fractures. Often, the cause of compression fractures is lowered bone mineral density as in osteoporosis. In the differential workup, also pathologic vertebral compression fractures need to be ruled out. Importantly, imaging techniques alone cannot safely differentiate between invasive lymphatic and osteoporotic vertebral fracture. Our goal was to identify the degree of unexpected positive histology in kyphoplasty for presumed osteoporotic vertebral compression fracture. ⋯ Therefore, we could demonstrate that the incidence of unexpected positive histology in vertebral compression fracture treated with kyphoplasty is significant (3.1%). As a conclusion, if a kyphoplasty is performed due to assumed osteoporotic vertebral compression fracture, a biopsy should be taken to safely rule out a pathological fracture caused by lymphatic bony invasion.
