UNASSIGNED: Bertolotti syndrome (BS) is defined as a congenital anomaly of the spine that includes sacralization of the lowest lumbar vertebra or lumbarization of the first sacral vertebra (i.e., lumbosacral transitional vertebra- LSTV) and the pain associated with this condition. The incidence of BS in adolescence is rare; we found only three such case reports of patients under the age of 18 in the literature, here will add a fourth.
UNASSIGNED: A 17-year-old female presented with a 2-month history of low back pain exacerbated by physical activity. Her neurological examination was normal, except for pain elicited when applying pressure over the sacroiliac joints bilaterally, and over the spinous process of the L5 vertebra. The computed tomography scan documented BS: (i.e., LSTV - Castellvi classification: Type IIa on the left side). She was successfully treated with nonsteroidal anti-inflammatory drugs (NSAIDs) alone.
UNASSIGNED: Here, we report a 17-year-old female who was symptomatic from BS and was successfully treated with NSAIDs.

BACKGROUND: Complex anatomical features are challenging for minimally invasive intradiscal therapy owing to insufficient visualization for accurate needle advancement. We report the case of a patient with dysraphic vertebral pathologies who presented with L5/S1 degeneration and was successfully treated with annuloplasty using the cone-beam computed tomography (CBCT)-assisted radiofrequency thermocoagulation system.
METHODS: A 34-year-old woman presented with a lower back and left radicular pain of L5/S1 discogenic origin, accompanied by spina bifida occulta and lumbosacral transitional vertebra. Radiofrequency annuloplasty was performed to preserve disc height and spinal stability, with real-time CBCT guidance for the congenital and degenerative conditions. The procedure relieved her left lower-extremity pain and magnetic resonance imaging revealed that the L5/S1 disc bulging decreased while the disc height was preserved.
CONCLUSIONS: Optimal accessibility of radiofrequency thermocoagulation and effective needle guidance using CBCT significantly improve the success rate of annuloplasty at the L5/S1 degenerative disc with severe vertebral deformity.

Common and minor birth defects, such as spina bifida occulta (SBO) and lumbosacral transitional vertebra (LSTV), are largely asymptomatic and overlooked. However, it is important for clinicians to consider their potential impacts on spinal stability. Neuromuscular scoliosis (NMS) is an abnormal lateral curvature of the spine that affects children with pre-existing neuromuscular conditions that are often complex to manage. The purpose of this case report is to describe the association of dual lumbosacral anomalies with complicated NMS. A 12-year-old boy was brought to the chiropractor by his mother for a consultation and possible care for the boy\'s back pain, progressive scoliosis, and long-standing walking abnormality that worsened quickly in the past 12 months. His mother stated that the patient walked on the balls of his left foot instead of putting weight on the heel ever since he started learning to walk. He had visited several pediatricians and neurologists since childhood. No one had been able to solve his problems. Radiographs showed right thoracolumbar curve of Cobb angle 20°, left pelvic obliquity, a cleft in the L5 and S1, and articulation of the transverse processes of L5 with the bilateral sacral alae. The patient was diagnosed with NMS and functional leg length discrepancy attributed to SBO and a LSTV at L5 level. Multimodal chiropractic care and foot orthotics were used. After 18 months of interventions, normal spinal curve, heel-to-toe gait, and posture balance were retrieved successfully. To date, few reports have been published on the impacts of SBO along with LSTV upon the lumbosacral spine. This article will allow a better understanding of the potential impacts of these birth defects and considerable consequences they would have on the growing spine and, therefore, may help to alleviate their impacts.

We present a case of double-crushed L5 nerve root symptoms caused by inside and outside of the spinal canal with spur formation of the lumbosacral transitional vertebra (LSTV). A 78-year-old man presented with 7-year history of moderate paresis of his toe and left leg pain when walking. Magnetic resonance imaging (MRI) revealed spinal stenosis at the L3/4 and 4/5 spinal levels and he underwent wide fenestration of both levels. Leg pain disappeared and 6-min walk distance (6MWD) improved after surgery, however, the numbness in his toes increased and 6MWD decreased 9 months after surgery. Repeated MR and 3D multiplanar reconstructed computed tomography (CT) images showed extraforaminal impingement of the L5 root by bony spur of the left LSTV. He underwent second decompression surgery of the L5/S via the left sided Wiltse approach, resulting in the improvement of his symptoms. The impingement of L5 spinal nerve root between the transverse process of the fifth lumbar vertebra and the sacral ala is a rare entity of the pathology called \"far-out syndrome (FOS)\". Especially, the bony spur formation secondary to the anomalous articulation of the LSTV (LSPA) has not been reported. These articulations could be due to severe disc degeneration, following closer distance and contact between the transverse process and the sacral ala. To our knowledge, this is the first report describing a case with this pathology and may be considered in cases of failed back surgery syndromes (FBSS) of the L5 root symptoms.
