BACKGROUND Hypertrophy of the ligamentum flavum is a pathological condition that causes neurological symptom (radiculopathy and / or myelopathy) and usually occurs in the thoracic,2 less frequently in the cervical spine that commonly involves thoracic spine. This study was conducted to analyse the clinical presentation and outcome of surgery of ossified ligamentum flavum at thoracic spine. ME...

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...

INTRODUCTION Lumbar spinal stenosis with symptomatic neurogenic claudication is a frequently encountered clinical entity which requires endoscopic or open spine surgery once the patients fail to respond to conservative therapies. In this case report we present a novel minimally invasive decompression technique using a fluid jet device (HydroCision Inc, Billerica, MA, USA) for a patient with sym...

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...

Abstract Ligamentum flavum cyst of the lumbar spine has seldom been described. The mechanism formation these cysts remains unknown, but it is thought to be part degenerative process. Although they are clearly visible on imaging studies, frequently wrongly diagnosed as ganglion or synovial cysts. Bone erosion rarely associated with this pathology. Most common symptom back and radicular pain due ...

Ossification of the ligamentum flavum is a rare cause of thoracic myelopathy. It develops in East Asians more frequently than in people from other areas. The exact pathophysiology has not been elucidated yet; however, it largely depends on biomechanical alterations, especially changes in the tensile force. Because the spinal cord is compressed from the posterior side, the first and most common ...
