A prospective analysis of adverse events in patients who undergo surgery for degenerative spondylolisthesis was recently published in The Spine Journal.
The researchers analyzed data and compared results to outcomes reported in the Spine Patient Outcomes Research Trial. The researchers found:
• No AEs in 57.6 percent of patients
• One AE in 17.4 percent of patients
• Two or more AEs in 17.4 percent of patients
Dural tears made up 6.5 percent of the adverse events, followed by intra-op bone-implantation interface failure requiring revision in 2.2 percent of the cases. The most common postoperative AEs were:
• UTI — 10.9 percent
• Delirium — 5.4 percent
• Neuropathic pain — 4.4 percent
• Deep wound infection — 3.3 percent
• Superficial wound infection — 3.3 percent
The odds of intraoperative AE were increased 9 percent per year of age admission, and length of stay was significantly influenced by two or more AEs. However, multiple comorbidities did not predispose the patient to more AEs, the study authors concluded.
