There are few epidemiological studies of spinal surgery in Asia and none in Japan. The goal of this study was to review spine surgeries performed in our group between 2004 and 2015 in a cross-sectional study, with a focus on the effects of the superaging society on the characteristics and trends of spinal surgeries. ⋯ Our data showed marked increases in the number of spine surgeries, the age of patients, and the number of surgeries for degenerative diseases. This large-scale study provides indicators for planning the future development of spine surgery and for treatment of spinal diseases in daily practice.

Posterior lumbar interbody fusion (PLIF)/transforaminal lumbar interbody fusion (TLIF) can have complications that require reoperation. The goal of the study was to identify risk factors for reoperation within 2 years after PLIF/TLIF. ⋯ Surgical invasiveness, as reflected by number of fused levels, operation time, EBL and dural tear, was associated with reoperation. Fusion of two or more levels is a strong risk factor for reoperation within 2 years after initial PLIF/TLIF. These slides can be retrieved under Electronic Supplementary Material.
