Bibliometric analysis of transforaminal lumbar interbody fusion in lumbar spine surgery.

OBJECTIVE: The objective of this study is to conduct a bibliometric analysis to examine the current condition, areas of interest, and rising trends of transforaminal lumbar interbody fusion in lumbar spine surgery (TLIF), as well as its importance in associated research domains. MATERIALS AND METHODS: An extensive collection of academic papers on the use of TLIF was obtained from the Web of Science between January 1, 2000, and November 5, 2023. Then, using a variety of tools like HisCite, VOSviewer, CiteSpace, and the bibliometrix package, a bibliometric study was carried out. This study included the collection of information on country, institution, author, journal, and keywords. RESULTS: A comprehensive analysis was undertaken on a total of 1,907 publications obtained from 181 journals, encompassing the contributions of 7,232 authors affiliated with 1,775 institutes spanning 57 countries/regions. Notably, the USA exhibited the highest number of publications, with 763 (40.03%) articles on TLIF. The most productive institution was Rush University, with 96 (5.03%) publications. The author with the highest publication output was Singh, Kern with 75 (3.93%) publications. World Neurosurgery demonstrated the highest level of productivity, having published a total of 211 (11.06%) articles. The most frequently used keywords were "TLIF", "spondylolisthesis" and "complication". Meanwhile, "workflow", "technical note" and "hidden blood loss" have been identified as the research frontiers for the forthcoming years. CONCLUSIONS: This paper provides a thorough evaluation of current research trends and advancements in TLIF. It includes relevant research findings and emphasizes collaborative efforts among authors, institutions, and countries.

Minimally invasive posterior cervical foraminotomy vs. anterior cervical discectomy and fusion in the treatment of patients with single-level unilateral cervical radiculopathy.

OBJECTIVE: The aim of this study was to observe the clinical efficacy and safety of minimally invasive posterior cervical foraminotomy (MI-PCF) and anterior cervical discectomy and fusion (ACDF) in the treatment of single-level unilateral cervical radiculopathy (SLUCR). PATIENTS AND METHODS: We retrospectively analyzed 81 patients with SLUCR in two hospitals from February 2020 to February 2022, including the MI-PCF group (n=40) and the ACDF group (n=41). The differences in neck and shoulder pain, visual analog score (VAS), upper limb radiating pain (VAS), and neck disability index (NDI) were compared. Operative time, intraoperative bleeding, hospital stay, and complications were also compared between the two groups. RESULTS: The degree of neck and shoulder pain relief at 1 day postoperatively was better in the ACDF group than in the MI-PCF group (p<0.05), while there were no significant differences between the two groups in terms of neck and shoulder pain relief at 1 month, 3 months, 6 months, and 12 months postoperatively, (p>0.05). There were no significant differences in the relief of upper limb radiating pain and the decrease of NDI scores between the two groups at 1 day, 1 month, 3 months, 6 months, and 12 months after surgery (p>0.05). The patients in MI-PCF group had shorter operative time, less bleeding, and shorter hospital stay, which were statistically different (p<0.05). There was no statistical difference in the complication rate between the two groups, (p>0.05). CONCLUSIONS: The clinical efficacy and safety of MI-PCF and ACDF in the treatment of SLUCR are satisfactory, meanwhile, MI-PCF has shorter operative time, less bleeding and shorter hospital stay than ACDF, which is worthy of clinical promotion.
