Сomputed tomography (CT) is widely used in the diagnosis of  degenerative pathology of the lumbar spine, but the relationship  between clinical manifestations of lumbar stenosis and its anatomical prerequisites has not been sufficiently studied to date.The objective: to determine the significance of the morphometric  parameters of lumbar stenosis according to CT scans and to  establish their relationship with the prevailing symptoms of the disease.Material and methods. Seventy-five consecutive patients with  clinically significant lumbar stenosis who underwent CT scan before  surgery were enrolled in this study. The average values of thirteen  different morphometric parameters were calculated at LIII–SI levels of the intervertebral discs and of the pedicels in the axial and sagittal views. The possibility of classification of clinical observations and the correlation of morphometric parameters with the clinical forms of lumbar stenosis were investigated using discriminant and logistic regression analysis. Results. CT scan with high probability allocates patients with  predominant symptoms of neurogenic claudication or bilateral  radiculopathy. The most significant morphometric predictors of this  clinical group are the depth of the lateral recesses and the cross-sectional area of the spinal canal.Conclusion. CT scan significantly expands the informative value of  magnetic resonance imaging and can be used in planning the  decompressive stage of the surgery intervention in patients with lumbar spinal canal stenosis.

ABSTRACTLumbar stenosis is a common disorder, usually characterized clinically by neurogenic claudication with or without lumbar/sacral radiculopathy corresponding to the level of stenosis. We present a case of lumbar stenosis manifesting as a multilevel radiculopathy inferior to the nerve roots at the level of the stenosis. A 55-year-old gentleman presented with bilateral lower extremity pain with neurogenic claudication in an L5/S1 distribution (posterior thigh, calf, into the foot) concomitant with dorsiflexion and plantarflexion weakness. Imaging revealed grade I spondylolisthesis of L3 on L4 with severe spinal canal stenosis at L3-L4, mild left L4-L5 disc herniation, no stenosis at L5-S1, and no instability. EMG revealed active and chronic L5 and S1 radiculopathy. The patient underwent bilateral L3-L4 hemilaminotomy with left L4-L5 microdiscectomy for treatment of his L3-L4 stenosis. Postoperatively, he exhibited significant improvement in dorsiflexion and plantarflexion. The L5-S1 level was not involved in the operative decompression. Patients with radiculopathy and normal imaging at the level corresponding to the radiculopathy should not be ruled out for operative intervention should they have imaging evidence of lumbar stenosis superior to the expected affected level.

New data have been obtained for assessing the expression of genes of metalloproteinases and their tissue inhibitors (MMP-1, MMP-2, MMP-3, MMP-8, MMP-9, TIMP-1 and TIMP-2) in the Ligamentum flavum in patients with lumbar stenosis of spinal canal and dural sac. The features of the metabolism of the extracellular matrix (ECM) were revealed, the data obtained were compared with those for previously studied candidate genes. The search for relationships with the features of the ECM metabolic characteristics was carried out.The aim. To study the expression of genes of metalloproteinases and their tissue inhibitors in intraoperative biopsies of the Ligamentum flavum of patients with lumbar stenosis of the spinal canal and dural sac.Materials and methods. A group of 33 people (17 women, 16 men) with lumbar stenosis of the spinal canal and dural sac was studied; the average age is 45.73 ± 1.95 years. RNA was isolated from intraoperative biopsies of the Ligamentum flavum, reverse transcription was performed, and PCR using specific primers was performed.Results. In Ligamentum flavum of patients with stenosing processes of the spinal canal and dural sac, an increased activity of MMP-1 and insufficient response of TIMP-1 and TIMP-2 were found; the expression of MMP-1 increased synchronously with Dio2, and both genes decreased their activity with increasing age of the patient. In patients with Ligamentum flavum ossification, the MMR-8 gene was more actively expressed, and the synthesis of the mRNA of the MMR-9 gene decreased compared to the subgroup without ossification.

Abstract A case of congenital lumbar stenosis producing lower extremity spasticity and bladder dysfunction in a young child is presented. Myelography demonstrated a marked stenosis of the spinal canal at L-2, L-3, and decompressive laminectomy resulted in a marked improvement in symptoms. A discussion of lumbar stenosis in general illustrates that it is extremely rare for this condition to become symptomatic during childhood. The literature on congenital lumbar stenosis is reviewed.

Lumbar stenosis is characterised by decrease in spinal canal, neural foramina, lateral nerve .with the narrowing or compression which results in pain and progressive loss. The main objective of the review was to present etiology, pathogenesis and most importantly its clinical presentation along with the necrosis of foot . Study shows that lumbar stenosis can show its improvement by surgical Lumbar decompression and endoscopy.
