Perfetti DC, Katz A, Job A, et al. - This study was intended to apply the New York Statewide Planning and Research Cooperative System (SPARCS) database to identify the risk factors and incidence of subsequent lumbar spine surgery in patients undergoing primary lumbar disc arthroplasty. Between 2005 to 2013, researchers examined the New York SPARCS inpatient database to retrospectively distinguish patients who had undergone isolated lumbar disc arthroplasty. They applied SAS version 9.4 to examine de-identified data. For the longitudinal follow-up, each patient had a unique patient identifier allowing. Between January 2005 and September 2013, a sum of 1,372 patients who had undergone an inpatient lumbar disc arthroplasty procedure were included in the study. A 17.6% incidence of subsequent lumbar spine surgery was distinguished after inpatient lumbar disc arthroplasty, and an 8.8% re-operation rate at two years. As per the data, 14.2% had undergone a subsequent lumbar fusion procedure over the study duration. It was shown that diabetes mellitus was the only patient demographic factor to significantly affect the odds of lumbar spine re-operation. In New York State, inpatient lumbar disc arthroplasty procedures declined over the study duration. Future study is required to assess whether these findings associate with the newest generation of lumbar disc arthroplasty designs.
