Global research characteristics and trends of infection after spinal implant surgery: a bibliometric analysis

Abstract

Background: With the growing awareness of postoperative infection, increasing focus has been placed on infection after spinal implant surgery (IASIS). This study aimed to explore the development and trends of research regarding IASIS using bibliometric analysis. Methods: Scientific articles on IASIS research published between February 1, 2000, and December 31, 2020 were retrieved from the Web of Science database. Results: A total of 820 publications were included in the bibliometric analysis, with studies originating from 46 countries and 6 languages. Researchers from the United States published the highest number of articles and collaborated closely with researchers in Canada, Germany, and Japan. The author with the most publications was Alexander R. Vaccaro. The journal with the most articles and citations was Spine. Most of the research was performed on risk factors and the incidence of IASIS. Co-occurrence analysis revealed that the most recent research trend was likely related to the management of IASIS and the international consensus meeting. Three clusters of research were identified through a thematic map: diagnosis and treatment of IASIS, scoliosis-related infection, and risk factors and prevention of IASIS. Conclusions: Research on IASIS increasingly grew between 2000 and 2020. Spinal surgeons and institutes from the United States had the highest number of publications and academic impact in this field. Diagnosisrelated problems and multidisciplinary work on IASIS require further attention in the future. Current trends in IASIS are likely associated with IASIS management and the international consensus meeting.

The impact of negative pressure wound therapy on surgical wound infection, hospital stay and postoperative complications after spinal surgery: A meta‐analysis

“…[4][5][6] For spinal fusion surgery with implants, post-surgical wound infection is a serious complication. 7,8 Postoperative wound infections not only lead to longer hospital stays and higher hospitalisation costs, but can also lead to a greater risk of secondary surgery, osteomyelitis and even death. 8,9 Therefore, new ways to reduce the rate of wound infection after spinal surgery are urgently needed.…”

“…Despite the proper use of antibiotic prophylaxis, minimally invasive surgical techniques and more effective perioperative care, the incidence of postoperative wound infections and postoperative complications following spine surgery has been reported to range from 2% to 20% 4–6 . For spinal fusion surgery with implants, post‐surgical wound infection is a serious complication 7,8 . Postoperative wound infections not only lead to longer hospital stays and higher hospitalisation costs, but can also lead to a greater risk of secondary surgery, osteomyelitis and even death 8,9 .…”
