Conservative treatment with analgesics and brace can potentially delay diagnosis and treatment of underlying malignant disease. We recommend biopsy during PVP as a standard procedure, to insure not to overlook any underlying malignancy despite the MRI-scan, blood analysis, and clinical examination being inconspicuous.

Retrospective study of benchmarking database. ⋯ There was variation in implant costs between medical centers and manufacturers of implants, with a small negative relationship between purchasing volume and cost. Transparency in cost negotiation, surgeon awareness of costs and alignment between surgeon and hospital goals may help decrease the cost of spinal implants, and the cost of care for patients undergoing instrumented fusions.
