Human lumbar spine usually consists of five vertebrae; however, some individuals have vertebral anomalies with four or six lumbar vertebrae because of sacralized fifth lumbar vertebra (L5 sacralization) or lumbarized first sacral vertebra (S1 lumbarization), respectively. These vertebral anomalies are called lumbosacral transitional vertebra (LSTV). Although LSTV is an asymptomatic anomaly, it is known to cause misconception in spinal counts and in spinal level at lumbar spinal surgery. The purpose of this study is to evaluate how LSTV affects the diagnosis and surgeries in lumbar spine disorders...

PURPOSE: Weight bearing does alter the dimension of lumbar spinal canal, but no study has analyzed its clinical correlation. This study aims to evaluate whether the changes in dural sac cross-sectional area (DSCA) and sagittal anteroposterior (AP) diameter on standing magnetic resonance imaging (MRI) correlate better with clinical symptoms of lumbar spinal stenosis. METHODS: Seventy consecutive patients with neurogenic claudication were prospectively recruited to undergo a 0...

OBJECTIVE The flexed posture of the proximal (L1-3) or distal (L4-S1) lumbar spine increases the diameter of the spinal canal and neuroforamina and can relieve symptoms of neurogenic claudication. Distal lumbar flexion can result in pelvic retroversion; therefore, in cases of flexible sagittal imbalance, pelvic retroversion may be compensatory for lumbar stenosis and not solely compensatory for the sagittal imbalance as previously thought. The authors investigate underlying causes for pelvic retroversion in patients with flexible sagittal imbalance...

Kevin Phan, Ian Teng, Konrad Schultz, Ralph J Mobbs
Lumbar spinal stenosis is typically a degenerative condition that leads to compression of the spinal canal and lateral recess, resulting in leg pain and walking disability. Surgical management is indicated after failure of non-surgical management or rapidly worsening neurological impairment. The traditional approach is a laminectomy with foraminotomy and partial facetectomy but a newer minimally invasive option, unilateral laminectomy for bilateral decompression (ULBD), seems to demonstrate the better postoperative outcomes due to its unilateral exposure...

Posterior decompression surgery which enlarges the spinal canal in cases with lumbar spinal stenosis is the most fundamental technique in spine surgery, but controversy still remains for the exact technique. Because nerve roots run under the ventral side on the superior articular process (SAP), achieving both facet joint preservation and nerve root decompression is problematic. In conventional laminotomies or laminectomies, medial facetectomies are performed to decompress the nerve root, but it is ideal to preserve the facet joints completely for preserving joint stability...

BACKGROUND: The dilemma in managing patients with low back ache lies in differentiating radiculopathy from lumbar canal stenosis. This has a huge bearing in patients being planned for surgical intervention as underperforming leads to failed back syndrome whereas over-doing leads to instability. There still remains a loophole in clinically diagnosing lumbar canal stenosis. AIM: We opt to utilize a simple bedside clinical examination in routinely assessing patients presenting with low back ache in ruling out underlying canal stenosis...

BACKGROUND: Context: Although lumbar spinal stenosis often presents as a degenerative condition, some patients present with symptoms from lifelong narrowing of the spinal canal. These patients have congenital stenosis (CS) and present with symptoms of stenosis at a younger age. CS patients often have a distinct pathophysiology with fewer degenerative changes but present with multi-level involvement. In the setting of neurological symptoms, decompression-alone while preserving stability, has been proposed for both patient populations...

BACKGROUND: Tethered cord syndrome is a well-known complication after myelomeningocele (MMC) repair in childhood. However, late complications in adults with a repaired MMC are not well understood. In particular, the influence of a degenerative spinal deformity on a sustained tethered cord is still unclear. CASE DESCRIPTION: A 63-year-old man with a repaired MMC exhibited a progressive gait disturbance and numbness in both lower limbs. Magnetic resonance imaging demonstrated that the tethered spinal cord was compressed by severe canal stenosis along the entire lumbar spine...

INTRODUCTION: By using a combination of magnetic resonance imaging (MRI) and computed tomography (CT) of the lumbar spine, it is possible to distinguish between spinal stenosis caused by bone compression and specific soft tissue epidural intraspinal lesions that cause localized spinal canal stenosis and neural compression. Examples include facet cysts and yellow ligament hypertrophy. Many of these patients are elderly with medical comorbidities that make open surgery problematic. MATERIALS & METHODS: This is a study of patients with predominantly soft tissue stenosis being treated with targeted intraspinal radiofrequency (RF) heat ablation...
