This is a prospective single center study designed to compare balloon kyphoplasty to non-surgical management (NSM) in the treatment of mildly painful, acute vertebral body compression fractures in multiple myeloma patients. Because of the pilot nature and the small sample size of the study, patient randomization will NOT be stratified. Patients with mildly symptomatic vertebral compression fractures (VCFs) will undergo a 1:1 randomization either balloon kyphoplasty or non surgical management. Randomization assignments will be generated by computer and investigator notified once the patient enrolled.
