Many patients undergoing elective thoracic or lumbar fusion procedures are obese, but the contribution of obesity to complications in spine surgery has not been defined. The authors retrospectively assessed the prevalence of obesity in a cohort of patients undergoing thoracic and lumbar fusion and correlate the presence of obesity with the incidence of operative complications. ⋯ Obesity is a prevalent condition in patients undergoing elective fusion for degenerative spinal conditions and may increase the prevalence and incidence of perioperative complications. In their analysis, the authors correlated increasing BMI and increased risk of significant postoperative complications. The correlation of obesity and perioperative complications may assist in the preoperative evaluation and selection of patients for surgery.

Many patient complications have been reported after the use of the pedicle subtraction osteotomy (PSO) technique. To the authors' knowledge, no previous reseachers have reported on the causes of complications after using the single-stage PSO technique with a posterior approach. The purpose of this study was to investigate complications after the procedure, to clarify the factors influencing the complications, and to identify ways to minimize complications. ⋯ Intraoperative complications can be prevented or the risks minimized with adequate surgical training. Most of the late-onset complications in these patients were related to the progression of kyphosis. The frequency of complications was closely correlated with patient satisfaction at follow up. Correcting the C-7 plumb line value with minimal complications appeared to lead to better clinical results.

Anterior cervical discectomy (ACD), ACD with interbody fusion (ACDF), ACDF with placement of an anterior plate system (ACDFP), corpectomy, and corpectomy with plate placement are used to fuse the cervical spine. The authors conducted a metaanalysis of studies published after 1990 in which fusion rates achieved with each procedure were reported for patients with degenerative disease at one, two, and three disc levels. ⋯ The anticipated fusion rate is one of several factors that may guide surgical decision making. Anterior cervical decompression and fusion results in high fusion rates. The results of the authors' study show that regardless of the number of levels fused, the use of an anterior cervical plate system significantly increases the fusion rate. For two-disc-level disease, there was no significant difference between ACD with a plate system or corpectomy with a plate system. For three-disc-level disease, however, the evidence suggests that corpectomy with plate placement is associated with higher fusion rates than discectomy with plate placement.
