Multi-joint disease pathologies in the lumbar spine, including ligamentum flavum (LF) hypertrophy and intervertebral disc (IVD) bulging or herniation contribute to spinal stenosis (LSS), a highly prevalent condition characterized by symptomatic narrowing of canal. Clinical hypertrophic LF is loss elastic fibers increase collagen fibers, resulting fibrotic thickening scar formation. In this stud...

BACKGROUND Previous studies have shown that if performed without radiographic guidance, the loss of resistance (LOR) technique can result in inaccurate needle placement in up to 30% of lumbar epidural blocks. To date, no study has shown the efficacy of measuring the depth of the posterior complex (ligamentum flavum, epidural space, and posterior dura) ultrasonographically to distinguish true an...

Calcification of Ligamentum Flavum (CLF) is an uncommon disorder. We present a 56-year-old patient with an acute inflammatory, febrile neck pain and higher value of ESR mimicking spine infection. The imaging investigations conclude for the diagnosis of calcification of the ligamentum flavum. Our observation illustrate the difficulties to differentiate, clinically, infection and calcium pyrophos...

Introduction The lower back ache or lumbago is a common musculoskeletal complaint patients present with, especially among the elderly. It can be caused mostly by degenerative changes like ligamentum flavum hypertrophy associated with aging and physical strain, first causing spinal canal narrowing leading to stenosis later. MRI provides excellent high-resolution images of ...

Abstract Background The purpose of this study was to establish a novel rat model for ligamentum flavum (LF) hypertrophy using increased motion lumbar and elucidate the etiology (LFH). Methods A total number 30 male rats were used. induced by surgical resection L5/6 posterior elements ( n = 15). other underwent sham operation (n After 8 weeks, all taken lateral plain X-rays. LF from in both grou...

We present 4 cases of facet cyst haematoma in the ligamentum flavum of the lumbar spine. All patients presented with a one-to-3-month history of back pain or numbness in the legs, and sudden neurological deterioration. One also developed cauda equina syndrome and another developed radiculopathy. In all cases, magnetic resonance imaging showed a mass with high signal intensity on both T1- and T2...

Calcification and ossification of the ligamentum flavum or of the posterior longitudinal ligament are causes of compressive myelopathy, more frequent in the lower thoracic levels, and extremely rare in Western populations. Surgical decompression is the only therapy, but the disease is usually progressive, and its recurrence after surgery is common. Inflammatory mediators might play a role in th...

Degenerative changes in the lumbar spine can be followed by cystic changes. Most reported intraspinal cysts are ganglion or synovial cysts. Ligamentum flavum pseudocyst, as a cystic lesion in the lumbar spine, is a rare and unusual cause of neurologic signs and symptoms and is usually seen in elderly persons (due to degenerative changes). They are preferentially located in the lower lumbar regi...
