Background: Bertolotti's syndrome is defined by back pain and/or radicular symptoms attributed to a congenital lumbosacral transitional vertebra (LSTV). There are few studies that discuss the surgical management of Bertolotti's syndrome. Here, we report long-term outcomes after resecting a pseudoarthrosis between the sacrum and L5 in two teenage patients, along with a review of literature.
Case descriptions: Surgical resection of a lumbosacral bridging articulation (LSTV type IIa) was performed in two patients, 15 and 16 years of age who presented with intractable back pain. The adequacy of surgery was confirmed with postoperative studies. In both patients, pain and functional status improved within 6 weeks and have remained improved at last follow-up.
Conclusion: Surgical removal of a pathologic L5 transverse process fused to the sacral ala in two young patients with Bertolotti's syndrome improved postoperative pain and increased overall function. Given the progressive nature of Bertolotti's syndrome, surgical intervention in young patients should be considered to mitigate years of chronic pain and attendant morbidity.
