Features of clinical manifestations, diagnosis and treatment of Bertolotti syndrome: a clinical case

BACKGROUND: One of the causes of pain in the lumbar spine may be congenital spinal column malformations. Bertolotti syndrome is a clinical and radiological symptom complex associated with sacralization of the LV vertebra, leading to disruption of the biomechanics of the lumbosacral spine and accelerated degeneration of facet joints and intervertebral discs, followed by foraminal and central stenosis of the spinal canal. The clinical manifestations of the disease can be polymorphic, and their cause is multifactorial. Thus, along with pain in the lumbar spine, patients with sacralization of the LV vertebra suffer from numbness and paresthesia in the lower extremities. The incidence of pathology ranges from 4% to 8%, mainly affecting elderly and mature people. CLINICAL CASE DESCRIPTION: Patient S was born in 1982 with long-term nonspecific pain in the back and lower limb; she presented to the Neurosurgical Department of the Irkutsk Scientific Center for Surgery and Traumatology. During a clinical neurological examination and additional introscopic studies of the lumbar spine, dorsopathy diagnosed. Degenerative spondyloarthrosis LIV-LV grade III according to D. Weishaupt. Sacralization of the LV vertebra type IIa according to Castellvi A.E. Syndrome of lumbar ischialgia on the right. Persistent pain and muscle-tonic syndrome. Minimally invasive interventional treatment was performed: pulsed radiofrequency ablation of the dorsal ganglion and radicular nerve at the level of the foraminal openings LIV-LV on the right and thermal radiofrequency ablation of the recurrent nerve of Luschka at the level of LIV-LV and LV-SI on the right. In the postoperative period, the intensity of the pain syndrome decreased, and the patient was discharged to work.
