A case-control study of risk alleles for degenerative disc disease (DDD) using magnetic resonance (MR) imaging for phenotyping. ⋯ In this large-scale study of common variants' correlation with the presence of DDD in the Northeast United States, we have found a novel and significant variant-to-variant interaction to be associated with the risk of developing DDD, corroborating and necessitating the inclusion of gene-gene interactions in predictive risk model development for DDD.Level of Evidence: 4.

Case report. ⋯ We highlight the utility of routine biopsy during kyphoplasty especially in patients with known history of malignancy. We emphasize that presumptions about the etiology of a VCF are difficult to make with multiple risk factors and that routine biopsy prevents incorrect presumptions such as in this case.Level of Evidence: 5.
