Oral pharmacological management of Bertolotti syndrome presenting as chronic low back pain - A case report and review of literature.

Background: Bertolotti syndrome (BS) is often a missed cause of chronic lower back pain in young individuals, commonly associated with the presence of anomalous lumbosacral transitional vertebrae.

Case Presentation: A 19-year-old female with no significant medical or family history presented with persistent lower back pain localized to the gluteal region and posterolateral aspect of the left lower back. The pain worsened over time and limited their movements, including walking. A Ferguson radiograph revealed fusion of the left transverse process of the L5 vertebral segment with the left sacral ala. History, examination findings, and radiological workup confirmed the diagnosis of BS. The patient preferred conservative management, receiving oral pharmacological therapy for six weeks, along with education on preventive measures and routine exercises for postural stability. At a six-month follow-up, the patient remained asymptomatic and managed well.

Conclusions: Conservative oral pharmacological treatment presents a unique and viable alternative to traditional methods for managing BS, which often involve surgery or steroids/anesthetics at the pseudo-articulation site. Given that BS is common yet underdiagnosed in young patients with chronic back pain, this report also underscores the importance of including it in differential diagnoses for chronic lower back pain in this demographic.
