INTRODUCTION: This is a narrative overview of the pathophysiology, investigation and management of Degenerative Cervical Myelopathy (DCM). This review article also takes a look ahead to the impact high resolution MRI may have on treatment. BACKGROUND: DCM is the most common cause of spinal dysfunction and yet it remains poorly understood. It is becoming increasingly common in our ageing population. Disc and facet joint abnormalities, osteophytes, spondylothisthesis and ligamentous hypertrophy all act together to produce spinal canal and neuronal foramina stenosis which in turn causes neural compromise...

BACKGROUND: To compare morphometric factors of cervical spine in the cervical stenosis on dynamic and static magnetic resonance imaging. To analyse the relationship between the severity of myelopathy and morphometric parameters. METHODS: Patients with cervical canal stenosis scanned with MRI in neutral (N), flexion (F) and extension (E) positions were retrospectively reviewed. All cases were evaluated in Nurick and Muhle grades. Following parameters were measured: anterior and posterior length of the cervical cord (aLCC, pLCC), mid-cord distance (L value), cervical cord angle (CCA), cervical lordosis, spine/cord (S/C) angle ratio, spinal cord (SC) area, cerebrospinal fluid (CSF) area, and CSF reserve ratio (CSF/CSF plus SC)...

We describe a case of lumbar stenosis in which retrospective spectral analysis using dual-layer spectral detector computed tomography (CT) had the ability to expand the evaluable region in the spinal canal. Spinal canal stenosis is a common condition whose symptoms (such as lower back and leg pain with walking) deteriorate the quality of life. Generally, magnetic resonance imaging (MRI) and CT myelography are performed to diagnose canal stenosis. Dual-layer spectral detector CT can yield virtual monochromatic imaging and retrospective on-demand spectral analysis without a prescan setting...

The clinical features and etiology of low back pain(LBP)and buttock pain(BuP)has been poorly understood. We report a case of long-term BuP that was successfully treated with gluteus medius muscle(GMeM)decompression under local anesthesia. A 71-year-old man was referred to our hospital because of long-term BuP and claudication. Left BuP that radiated to the left thigh was observed. The pain was mostly triggered by palpation at the middle of the iliac crest and greater trochanter. Lumbar and pelvic radiograms showed no significant lesions...

BACKGROUND: Degenerative diseases of the lumbar spine and associated lower back pain represent a major epidemiological and health-related economic challenge. A distinction is made between specific and unspecific lower back pain. In specific lower back pain lumbar disc herniation and spinal canal stenosis with or without associated segment instability are among the most frequent pathologies. Diverse conservative and operative strategies for treatment of these diseases are available. OBJECTIVES: The aim of this article is to present an overview of current data and an evidence-based assessment of the possible forms of treatment...

OBJECTIVE: Anterior cervical corpectomy and fusion (ACCF), in which a ventral constriction is resected, can decompress myelopathy and is considered the optimal treatment for ossification of the posterior longitudinal ligament (OPLL) up to now. However, its disadvantages are incomplete decompression, high surgery- and implant-related complication rates, and extremely surgical technique demanding. Our object was to introduce anterior controllable antedisplacement fusion (ACAF), a new surgical technique to treat OPLL, and compare it with ACCF...

INTRODUCTION: Lumbar spinal stenosis (LSS) is one of the most frequent neurosurgical affections. It has been reported that the anatomical shape of the spinal canal (oval, round, trefoil) predicts outcome of bilateral decompression performed in an undercutting technique via a unilateral laminotomy in monosegmental LSS. The poorest results were observed in a trefoild spinal canal, leading to the proposal of using a bilateral instead of a unilateral laminotomy. We have been routinely performing a unilateral microsurgical approach with undercutting to decompress both sides of the spinal canal for more than a decade...

Ligamentum flavum (LF) hypertrophy is one of the main factors of lumbar spinal canal stenosis (LSCS). The primary object of this study is to clarify the existence of epiligament in the LF and its role in hypertrophy, and to develop an LF hypertrophy animal model. A cadaveric spine from a 30-year-old man was used to investigate the existence of epiligament in LF. Five LF samples from LSCS patients were obtained to evaluate hypertrophied LF. To create a rat model, we destabilized the lumbar spine. Each LF was sagittally cut for histological evaluation...

Surgery for thoracic disc herniation and spinal stenosis is comparatively rare and often demanding. The goal is to achieve sufficient decompression without manipulating the spinal cord. Individual planning and various surgical techniques and approaches are required. This anatomical study examines the feasibility of a novel full-endoscopic uniportal technique with a transthoracic retropleural approach for decompression of the anterior thoracic spinal canal. Operations were performed on three fresh adult cadavers...
