Treatment of painful osteoporotic compression and burst fractures using kyphoplasty: a prospective observational design.
The aim of this study was to test the hypothesis that kyphoplasty is an effective treatment in painful osteoporotic vertebral fractures, even with involvement of the posterior cortical wall. ⋯ Kyphoplasty is effective in the treatment of painful osteoporotic vertebral compression and burst fractures, at least under medium-term conditions. The potential complication of procedure-related secondary narrowing of the spinal canal by the retropulsed posterior wall in burst fractures appears to be more of a theoretical than an actual risk.

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.

Antimicrobial prophylaxis (AMP) reduces the rate of surgical site infection (SSI) in lumbar spine surgery, but a great deal of variation exists regarding the timing and duration of AMP. The authors had previously used prophylactic antibiotics for 5 to 7 postoperative days. Based on the Centers for Disease Control and Prevention (CDC) guideline, the AMP period was changed to the day of surgery only. In the current study, the authors compared the rate of SSI in lumbar spine surgeries between two different protocols of AMP. ⋯ Data in the current study did not demonstrate a difference in the rate of SSI between the two different AMP protocols. Based on the CDC guideline, a single dose of AMP was proven to be efficacious for the prevention of SSI in lumbar spine surgeries. A shorter duration of first-generation cephalosporin use may effectively prevent the emergence of antibiotic-resistant bacterial infection.

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.
