Ultrasound-Guided Injection Treatment of Low Back Pain Caused by Bertolotti Syndrome

Functional outcomes of microdiscectomy in Bertolotti syndrome: the relationship between lumbosacral transitional vertebrae and lumbar disc herniation: a prospective study in Greece

STUDY DESIGN

The lumbosacral transitional vertebrae (LSTV) in patients with Bertolotti syndrome (BS) cause alterations in the biomechanics of the lumbosacral junction. These entities have been associated with secondary conditions, such as lumbar disc herniation (LDH).

PURPOSE

To investigate the clinical outcomes of microdiscectomy in patients with symptomatic LDH and BS.

OVERVIEW OF LITERATURE

There is limited data in the literature on the functional outcomes of patients with LSTV who undergo microdiscectomy.

METHODS

This study enrolled 308 patients diagnosed with LDH and concurrent LSTV. All patients underwent microdiscectomy. Clinical evaluation was performed preoperatively and at distinct follow-up intervals of 1, 3, 6, and 12 months, and 2 and 5 years postoperatively. Assessment included clinical examination and implementation of the well-established, patient-reported outcome measures Visual Analog Scale (VAS) and Short-Form 36 (SF-36) Medical Health Survey Questionnaire for Health-Related Quality of Life (HRQoL) analysis. Furthermore, the anatomical relationship between LSTV and LDH was also studied.

RESULTS

The SF-36 indices and VAS score were statistically significantly ameliorated within the follow-up period. Maximum improvement was noted at 3 months, with further minimal improvement after 6 months, and stabilization of indices until the end of followup. Castellvi type IB was the most frequent LSTV type. The adjacent level (L4-L5) just above the LSTV was the most affected with an incidence of 72.1%. In the subgroups of Castellvi type IA, IIA, and IIIA, the LDH side was ipsilateral with the LSTV in 38.3% of patients. In this study, all patients underwent microdiscectomy and demonstrated favorable clinical outcomes (functional recovery and pain relief) and notable amelioration of HRQoL.

CONCLUSIONS

To the best of our knowledge, this is the first study to conduct a holistic assessment in an attempt to delineate the impact of LSTV presence on the postoperative HRQoL of these individuals.

Techniques in medicine: ipsilateral transforaminal epidural steroid injection in Bertolotti's syndrome

Bertolotti's syndrome, also known as lumbosacral transitional vertebrae, is a relatively rare spinal condition characterized by an anatomical variation in the lower spine. Conservative approaches such as physical therapy, anti-inflammatory medications and lifestyle modifications may be recommended for mild cases. In more severe cases or when conservative measures fail to provide relief, injections such as may be considered to alleviate pain. This case is unique in that we document a challenging technique of ipsilateral transforaminal epidural steroid injection in a patient with Bertolotti's syndrome.
