Surgical management of complex lumbosacral anomaly with minimally invasive spinal fusion: A clinical image.

KEY CLINICAL MESSAGE: Lumbosacral junction anomalies represent a rather frequent finding in patients with low back pain. Involved healthcare professionals should be familiar with these dysplasias, in order to achieve proper diagnosis and optimize clinical outcomes.

ABSTRACT: Dysplastic alterations in lumbosacral junction represent a frequent finding in patients with low back pain. Lumbosacral transitional vertebra (LSTV), spina bifida occulta (SBO) and isthmic spondylolisthesis (IS) present recognized etiologies of low back pain. Herein, we present a rare case of concurrent presence of LSTV, SBO and IS in a middle-aged male individual who was presented with low back pain in our department. Considering the resistant to conservative treatment symptomatology in conjunction with clinical-radiologic presence of segmental instability, patient was subjected to uneventful minimally invasive lumbosacral fusion featuring complete recession of symptomatology directly postoperatively with no signs of recurrence until 6 months follow-up. To our best knowledge, coexistence of LSTV, IS and SBO in lumbosacral junction has never been described in contemporary literature. Whenever surgery is indicated, minimally invasive spinal fusion may be considered as a safe and effective alternative in these cases.
