Operative Treatment of Bertolotti Syndrome: Resection Versus Fusion

[Main clinical characteristics of pain in patients with lumbosacral transitional vertebrae]

OBJECTIVE

Based on an analysis of modern medical literature, to study the main clinical characteristics of pain in patients with transitional lumbosacral vertebrae.

MATERIAL AND METHODS

A search was made for articles in the scientific electronic libraries CYBERLENINKA, eLIBRARY, Google Scholar, and the electronic database of biomedical publications PubMed. Sixty-eight scientific publications corresponded to the stated goal.

RESULTS

The review of literature shows that the localization of pain in patients with transitional vertebrae corresponds to the zone of pseudarthrosis between the enlarged transverse process of the LV vertebra and the wing of the sacrum. In most patients, the pain is deep, not superficial. Pain intensity ranges from 3.0 to 8.4, reaching an average of 6.0 on the visual analog scale. Pain can radiate to one of the buttocks and the lower limb. The intensity of pain in the leg at the same time, on average, reaches 5.4 points. The pain syndrome can last for months, the course of the disease acquires a sluggish, undulating character with periodic exacerbations. The causes of exacerbations of pain may be excessive loads on the spine, concomitant vertebrogenic diseases and spinal injuries, excess weight, and in women, a history of pregnancy. Pain management can be either conservative or surgical. The scope of conservative treatment consists of using acupuncture and taking non-steroidal anti-inflammatory drugs. The greatest therapeutic effect is achieved with local injection therapy of analgesics and glucocorticoids at the neoarticulation point. The effectiveness of the course of therapeutic blockades reaches a period from several months to a year. The arsenal of surgical techniques includes pseudoartrectomy, radiofrequency denervation, minimally invasive endoscopic surgery, and transpedicular fusion. In most patients, after surgical treatment, complete relief of pain is noted.

CONCLUSION

The review provides information on the predominant localization of pain in patients with transitional vertebrae, its nature, intensity, irradiation, duration, causes of exacerbation, as well as the effectiveness of the methods of conservative and surgical treatment.

A systematic review and bibliometric study of Bertolotti's syndrome: clinical characteristics and global trends

PURPOSE

Bertolotti's syndrome is a prevalent congenital deformity. However, many physicians fail to include it in their differential diagnosis for low back pain (LBP), which results in missed diagnosis or misdiagnosis. There is still a lack of standardized treatment and management strategies for Bertolotti's syndrome. This study aimed to review the clinical characteristics and management of Bertolotti's syndrome and reports bibliometric insights in advancements in Bertolotti's syndrome research.

METHODS

Studies published until 30 September 2022 were systematically reviewed according to the PRISMA guidelines. Three independent reviewers extracted the data and assessed the quality and risk of bias of the studies based on the methodological index of non-randomized studies (MINORS). SPSS, VOS viewer, and the Citespace software were used for the systematic review, visual analysis, data mining, mapping, and clustering of the retrieved articles, which presented clear and visual presentations of the structural patterns of published research in graphs.

RESULT

A total of 118 articles, describing a total of 419 patients with Bertolotti's syndrome, were included. There was an upward trend with a steady increase in the number of publications. The world map distribution showed that most publications were predominantly from North America and Asia. The most cited articles were published in the following journals: Spine, J Bone Joint Surg, and Radiology. The mean age of the patients was 47.7 years, and 49.6% of them were male. A total of 159 (96.4%) patients had LBP symptoms. The mean symptom duration was 41.4 months (74.8%), and most of the patients had Castellvi type II. Disc degeneration was the most reported comorbid spinal diseases. The mean methodological index of non-randomized studies score was 4.16±3.95 points (range, 1-21). A total of 265 (68.3%) patients underwent surgical treatments. Minimally invasive surgical techniques, prevalence, image classification, and disc degeneration were the current main research areas of Bertolotti's syndrome.

CONCLUSIONS

The steady increase in the number of publications demonstrated the increased attention of researchers on this topic. Our results showed a significant prevalence of Bertolotti's syndrome in patients with LBP and a long symptom duration before the initiation of treatment. Surgical treatments were commonly used to treat patients with Bertolotti's syndrome after a non-effective conservative treatment. Minimally invasive surgical techniques, prevalence, image classification, and disc degeneration are the major research areas of Bertolotti's syndrome.

Bilateral Bertolotti's Syndrome: A Case Report of an Uncommon Presentation of Chronic Low Back Pain in an Elder Patient

Lower back pain caused by anatomical lumbosacral transitional vertebra is known as Bertolotti's syndrome. We present the case of a 65-year-old male with persistent chronic lower back pain with radiological evidence of an anatomical lumbosacral pseudo-joint bilaterally. The patient underwent conservative treatment with lidocaine and steroids that helped to improve and manage his symptoms. Our patient is an elderly one, and it is quite uncommon for the first appearance of Bertolotti's syndrome. Therefore, Bertolotti's syndrome is a rare cause of lower back pain, and clinicians should consider it in the differential diagnosis.
